Class IIOMetadataNode

public IIOMetadataNode()

The basic constructor. Object is special, because it has no superclass, so there is no call to super().

public IIOMetadataNode(String nodename)

public Node appendChild(Node newChild)

Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.

Specified by:

appendChild in interface Node

Parameters:

newChild - The node to add.If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node

Returns:

The node added.

Throws:

DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to append is one of this node's ancestors or this node itself, or if this node is of type Document and the DOM application attempts to append a second DocumentType or Element node.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly or if the previous parent of the node being inserted is readonly.
NOT_SUPPORTED_ERR: if the newChild node is a child of the Document node, this exception might be raised if the DOM implementation doesn't support the removal of the DocumentType child or Element child.

public Node cloneNode(boolean deep)

Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent ( parentNode is null) and no user data. User data associated to the imported node is not carried over. However, if any UserDataHandlers has been specified along with the associated data these handlers will be called with the appropriate parameters before this method returns.
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any children it contains unless it is a deep clone. This includes text contained in an the Element since the text is contained in a child Text node. Cloning an Attr directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute (specified is true). Cloning an Attr always clones its children, since they represent its value, no matter whether this is a deep clone or not. Cloning an EntityReference automatically constructs its subtree if a corresponding Entity is available, no matter whether this is a deep clone or not. Cloning any other type of node simply returns a copy of this node.
Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly . In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent.

Specified by:

cloneNode in interface Node

Parameters:

deep - If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Returns:

The duplicate node.

public short compareDocumentPosition(Node other)
            throws DOMException

Parameters:

other - The node to compare against the reference node.

Returns:

Returns how the node is positioned relatively to the reference node.

Throws:

DOMException - NOT_SUPPORTED_ERR: when the compared nodes are from different DOM implementations that do not coordinate to return consistent implementation-specific results.

                         String version)

This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in . The specialized object may also be obtained by using binding-specific casting methods but is not necessarily expected to, as discussed in . This method also allow the implementation to provide specialized objects which do not support the Node interface.

Specified by:

getFeature in interface Node

Parameters:

feature - The name of the feature requested. Note that any plus sign "+" prepended to the name of the feature will be ignored since it is not significant in the context of this method.

version - This is the version number of the feature to test.

Returns:

Returns an object which implements the specialized APIs of the specified feature and version, if any, or null if there is no object which implements interfaces associated with that feature. If the DOMObject returned by this method implements the Node interface, it must delegate to the primary core Node and not return results inconsistent with the primary core Node such as attributes, childNodes, etc.

Since:

DOM Level 3

public Node getFirstChild()

The first child of this node. If there is no such node, this returns null.

getLength in interface NodeList

public String getLocalName()

Returns the local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.

Specified by:

getLocalName in interface Node

Since:

DOM Level 2

public String getNamespaceURI()

The namespace URI of this node, or null if it is unspecified (see ).
This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.

Note: Per the Namespaces in XML Specification [XML Namespaces] an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.

Specified by:

getNamespaceURI in interface Node

Since:

DOM Level 2

public Node getNextSibling()

The node immediately following this node. If there is no such node, this returns null.

Specified by:

getNextSibling in interface Node

public String getNodeName()

The name of this node, depending on its type; see the table above.

Specified by:

getNodeName in interface Node

public short getNodeType()

A code representing the type of the underlying object, as defined above.

Specified by:

getNodeType in interface Node

public String getNodeValue()

The value of this node, depending on its type; see the table above. When it is defined to be null, setting it has no effect, including if the node is read-only.

Specified by:

Specified by:

getOwnerDocument in interface Node

public Node getParentNode()

The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.

Specified by:

getParentNode in interface Node

public String getPrefix()

The namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect, including if the node is read-only.
Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.
Setting the prefix to null makes it unspecified, setting it to an empty string is implementation dependent.
Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:

getPrefix in interface Node

The name of the element. If Node.localName is different from null, this attribute is a qualified name. For example, in:

 <elementExample id="demo"> ...
 </elementExample> , 

tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the tagName of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document.

Specified by:

getTagName in interface Element

public String getTextContent()
            throws DOMException

This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed and the returned string does not contain the white spaces in element content (see the attribute Text.isElementContentWhitespace). Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
The string returned is made of the text content of this node depending on its type, as defined below:

Node type	Content
ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE	concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the node has no children.

public Node insertBefore(Node newChild,
                         Node refChild)

Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed.

Note: Inserting a node before itself is implementation dependent.

Parameters:

newChild - The node to insert.

refChild - The reference node, i.e., the node before which the new node must be inserted.

Returns:

The node being inserted.

Throws:

DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node's ancestors or this node itself, or if this node is of type Document and the DOM application attempts to insert a second DocumentType or Element node.

public boolean isEqualNode(Node arg)

Tests whether two nodes are equal.
This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode(). All nodes that are the same will also be equal, though the reverse may not be true.
Two nodes are equal if and only if the following conditions are satisfied:

• The two nodes are of the same type.
• The following string attributes are equal: nodeName, localName, namespaceURI, prefix, nodeValue . This is: they are both null, or they have the same length and are character for character identical.
• The attributes NamedNodeMaps are equal. This is: they are both null, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.
• The childNodes NodeLists are equal. This is: they are both null, or they have the same length and contain equal nodes at the same index. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.

For two DocumentType nodes to be equal, the following conditions must also be satisfied:

• The following string attributes are equal: publicId, systemId, internalSubset.
• The entities NamedNodeMaps are equal.
• The notations NamedNodeMaps are equal.

On the other hand, the following do not affect equality: the ownerDocument, baseURI, and parentNode attributes, the specified attribute for Attr nodes, the schemaTypeInfo attribute for Attr and Element nodes, the Text.isElementContentWhitespace attribute for Text nodes, as well as any user data or event listeners registered on the nodes.

Note: As a general rule, anything not mentioned in the description above is not significant in consideration of equality checking. Note that future versions of this specification may take into account more attributes and implementations conform to this specification are expected to be updated accordingly.

Specified by:

isEqualNode in interface Node

Parameters:

arg - The node to compare equality with.

Returns:

Returns true if the nodes are equal, false otherwise.

Since:

DOM Level 3

public boolean isSameNode(Node other)

Returns whether this node is the same node as the given one.
This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.

Specified by:

isSameNode in interface Node

Parameters:

other - The node to test against.

Returns:

Returns true if the nodes are the same, false otherwise.

Since:

DOM Level 3

public boolean isSupported(String feature,

Specified by:

isSupported in interface Node

Parameters:

feature - The name of the feature to test.

version - This is the version number of the feature to test.

Returns:

Returns true if the specified feature is supported on this node, false otherwise.

Since:

DOM Level 2

public Node item(int index)

Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.

Specified by:

Returns:

Returns the associated namespace URI or null if none is found.

Since:

DOM Level 3

public String lookupPrefix(String namespaceURI)

Look up the prefix associated to the given namespace URI, starting from this node. The default namespace declarations are ignored by this method.
See for details on the algorithm used by this method.

Specified by:

lookupPrefix in interface Node

Parameters:

namespaceURI - The namespace URI to look for.

Returns:

Returns an associated namespace prefix if found or null if none is found. If more than one prefix are associated to the namespace prefix, the returned namespace prefix is implementation dependent.

Since:

DOM Level 3

public void normalize()

Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer [XPointer] lookups) that depend on a particular document tree structure are to be used. If the parameter "normalize-characters" of the DOMConfiguration object attached to the Node.ownerDocument is true, this method will also fully normalize the characters of the Text nodes.

Note: In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

Specified by:

normalize in interface Node

public void removeAttribute(String name)

Removes an attribute by name. If a default value for the removed attribute is defined in the DTD, a new attribute immediately appears with the default value as well as the corresponding namespace URI, local name, and prefix when applicable. The implementation may handle default values from other schemas similarly but applications should use Document.normalizeDocument() to guarantee this information is up-to-date.
If no attribute with this name is found, this method has no effect.
To remove an attribute by local name and namespace URI, use the removeAttributeNS method.

Specified by:

If a default value for the removed attribute is defined in the DTD, a new attribute immediately appears with the default value as well as the corresponding namespace URI, local name, and prefix when applicable. The implementation may handle default values from other schemas similarly but applications should use Document.normalizeDocument() to guarantee this information is up-to-date.
If no attribute with this local name and namespace URI is found, this method has no effect.
Per [XML Namespaces] , applications must use the value null as the namespaceURI parameter for methods if they wish to have no namespace.

public Node replaceChild(Node newChild,
                         Node oldChild)

Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.
If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.

Note: Replacing a node with itself is implementation dependent.

Specified by:

replaceChild in interface Node

Parameters:

newChild - The new node to put in the child list.

oldChild - The node being replaced in the list.

Returns:

The node replaced.

Throws:

DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to put in is one of this node's ancestors or this node itself, or if this node is of type Document and the result of the replacement operation would add a second DocumentType or Element on the Document node.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the parent of the new node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.
NOT_SUPPORTED_ERR: if this node is of type Document, this exception might be raised if the DOM implementation doesn't support the replacement of the DocumentType child or Element child.

public void setAttribute(String name,
                         String value)

Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute.
To set an attribute with a qualified name and namespace URI, use the setAttributeNS method.

Specified by:

setAttribute in interface Element

Parameters:

name - The name of the attribute to create or alter.

value - Value to set in string form.

Throws:

DOMException - INVALID_CHARACTER_ERR: Raised if the specified name is not an XML name according to the XML version in use specified in the Document.xmlVersion attribute.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

public void setAttributeNS(String namespaceURI,
                           String qualifiedName,
                           String value)

Adds a new attribute. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.
Per [XML Namespaces] , applications must use the value null as the namespaceURI parameter for methods if they wish to have no namespace.

Specified by:

setAttributeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute to create or alter.

qualifiedName - The qualified name of the attribute to create or alter.

value - The value to set in string form.

Throws:

public Attr setAttributeNode(Attr newAttr)

Adds a new attribute node. If an attribute with that name ( nodeName) is already present in the element, it is replaced by the new one. Replacing an attribute node by itself has no effect.
To add a new attribute node with a qualified name and namespace URI, use the setAttributeNodeNS method.

Specified by:

setAttributeNode in interface Element

Parameters:

newAttr - The Attr node to add to the attribute list.

Returns:

If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned.

Throws:

DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.

public Attr setAttributeNodeNS(Attr newAttr)

Adds a new attribute. If an attribute with that local name and that namespace URI is already present in the element, it is replaced by the new one. Replacing an attribute node by itself has no effect.
Per [XML Namespaces] , applications must use the value null as the namespaceURI parameter for methods if they wish to have no namespace.

Specified by:

setAttributeNodeNS in interface Element

Parameters:

newAttr - The Attr node to add to the attribute list.

Returns:

If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the replaced Attr node is returned, otherwise null is returned.

Throws:

DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.
NOT_SUPPORTED_ERR: May be raised if the implementation does not support the feature "XML" and the language exposed through the Document does not support XML Namespaces (such as [HTML 4.01]).

public void setIdAttribute(String name,
                           boolean isId)
            throws DOMException

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute . This affects the value of Attr.isId and the behavior of Document.getElementById, but does not change any schema that may be in use, in particular this does not affect the Attr.schemaTypeInfo of the specified Attr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.
To specify an attribute by local name and namespace URI, use the setIdAttributeNS method.

Specified by:

setIdAttribute in interface Element

Parameters:

name - The name of the attribute.

isId - Whether the attribute is a of type ID.

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if the specified node is not an attribute of this element.

                             boolean isId)
            throws DOMException

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute . This affects the value of Attr.isId and the behavior of Document.getElementById, but does not change any schema that may be in use, in particular this does not affect the Attr.schemaTypeInfo of the specified Attr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.

Specified by:

setIdAttributeNS in interface Element

Parameters:

namespaceURI - The namespace URI of the attribute.

localName - The local name of the attribute.

isId - Whether the attribute is a of type ID.

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute . This affects the value of Attr.isId and the behavior of Document.getElementById, but does not change any schema that may be in use, in particular this does not affect the Attr.schemaTypeInfo of the specified Attr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.

Specified by:

Parameters:

idAttr - The attribute node.

isId - Whether the attribute is a of type ID.

Throws:

public void setNodeValue(String nodeValue)
            throws DOMException

The value of this node, depending on its type; see the table above. When it is defined to be null, setting it has no effect, including if the node is read-only.

Specified by:

setNodeValue in interface Node

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly and if it is not defined to be null.

public void setPrefix(String prefix)

The namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect, including if the node is read-only.
Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.
Setting the prefix to null makes it unspecified, setting it to an empty string is implementation dependent.
Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:

setPrefix in interface Node

Throws:

DOMException - INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character according to the XML version in use specified in the Document.xmlVersion attribute.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed per the Namespaces in XML specification, if the namespaceURI of this node is null, if the specified prefix is "xml" and the namespaceURI of this node is different from " http://www.w3.org/XML/1998/namespace", if this node is an attribute and the specified prefix is "xmlns" and the namespaceURI of this node is different from "http://www.w3.org/2000/xmlns/", or if this node is an attribute and the qualifiedName of this node is "xmlns" [XML Namespaces] .

public void setTextContent(String textContent)
            throws DOMException

This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed and the returned string does not contain the white spaces in element content (see the attribute Text.isElementContentWhitespace). Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
The string returned is made of the text content of this node depending on its type, as defined below:

Node type	Content
ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE	concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the node has no children.
TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE	nodeValue
DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE	null

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
