Detailed Description

template<class T>
class regina::DiscSetTetData< T >

Stores data of type T for every normal disc inside a single tetrahedron.

Warning: This class converts the number of normal discs of a given type from LargeInteger to unsigned long. See the precondition below.

Precondition: The number of normal discs of a particular type in a particular tetrahedron can be represented by a long integer.; This class should only be used with embedded normal surfaces.; Type T has a default constructor and an assignment operator. That is, if a and b are of type T, then a can be declared with no parameters and can then receive the value of b using a=b.

Python:: Not present.

Member Typedef Documentation

§ DataPtr

template<class T >

typedef T* regina::DiscSetTetData< T >::DataPtr

A type that is a pointer to the data stored with each disc.

Constructor & Destructor Documentation

§ DiscSetTetData() [1/3]

template<class T >

regina::DiscSetTetData< T >::DiscSetTetData	(	const NormalSurface &	surface,
		size_t	tetIndex
	)

inline

Creates a new disc set corresponding to the discs of the given normal surface that lie within the given tetrahedron.

The data for each disc will remain uninitialised.

Parameters

surface	the normal surface whose discs we shall use.
tetIndex	the index in the triangulation of the tetrahedron that our discs must lie in; this must be between 0 and `tri.size()-1` inclusive, where `tri` is the triangulation containing the given normal surface.

§ DiscSetTetData() [2/3]

template<class T >

regina::DiscSetTetData< T >::DiscSetTetData	(	const NormalSurface &	surface,
		size_t	tetIndex,
		const T &	initValue
	)

inline

Creates a new disc set corresponding to the discs of the given normal surface that lie within the given tetrahedron.

The data for each disc will be initialised to the given value.

Parameters

surface	the normal surface whose discs we shall use.
tetIndex	the index in the triangulation of the tetrahedron that our discs must lie in; this must be between 0 and `tri.size()-1` inclusive, where `tri` is the triangulation containing the given normal surface.
initValue	the value with which to initialise the data corresponding to each disc.

§ DiscSetTetData() [3/3]

template<class T >

regina::DiscSetTetData< T >::DiscSetTetData	(	unsigned long	tri0,
		unsigned long	tri1,
		unsigned long	tri2,
		unsigned long	tri3,
		unsigned long	quad0,
		unsigned long	quad1,
		unsigned long	quad2,
		unsigned long	oct0 = `0`,
		unsigned long	oct1 = `0`,
		unsigned long	oct2 = `0`
	)

inline

Creates a new disc set where the number of discs of each type is explicitly given.

The data for each disc will remain uninitialised.

Parameters

tri0	the number of triangular discs surrounding vertex 0.
tri1	the number of triangular discs surrounding vertex 1.
tri2	the number of triangular discs surrounding vertex 2.
tri3	the number of triangular discs surrounding vertex 3.
quad0	the number of quadrilateral discs of type 0.
quad1	the number of quadrilateral discs of type 1.
quad2	the number of quadrilateral discs of type 2.
oct0	the number of octahedral discs of type 0.
oct1	the number of octahedral discs of type 1.
oct2	the number of octahedral discs of type 2.

§ ~DiscSetTetData()

template<class T >

virtual regina::DiscSetTetData< T >::~DiscSetTetData ( )

inlinevirtual

Destroys this disc set and deallocates all data arrays.

Note that no assumption is made about type T, so if data elements are pointers to dynamically allocated objects, these will not be destroyed.

Member Function Documentation

§ arcFromDisc()

unsigned long regina::DiscSetTet::arcFromDisc	(	int	arcFace,
		int	arcVertex,
		int	discType,
		unsigned long	discNumber
	)		const

inherited

Determines which normal arc of a given type on a given face of this tetrahedron corresponds to the given normal disc.

Precondition: The given normal disc actually meets a normal arc of the given type on the given face.

Parameters

arcFace	the face of this tetrahedron containing the normal arc (between 0 and 3 inclusive).
arcVertex	the vertex of this tetrahedron about which the normal arc runs (between 0 and 3 inclusive); arcFace and arcVertex should not be the same.
discType	the disc type of the given normal disc; this should be between 0 and 9 inclusive, as described in the DiscSpec class notes.
discNumber	indicates which normal disc of the given disc type is referred to (between 0 and `nDiscs(discType)-1` inclusive).

Returns: the number of the normal arc of the given type that belongs to the given normal disc. Arcs of a given type (where arcFace and arcVertex together define the arc type) are numbered starting at 0 from the tetrahedron vertex outwards.

§ data()

template<class T >

T& regina::DiscSetTetData< T >::data	(	int	discType,
		unsigned long	discNumber
	)

inline

Retrieves a reference to the data corresponding to the given normal disc.

Parameters

discType	the disc type of the given normal disc; this should be between 0 and 9 inclusive, as described in the DiscSpec class notes.
discNumber	indicates which normal disc of the given disc type is referred to; this should be between 0 and `nDiscs(discType)-1` inclusive.

Returns: a reference to the data corresponding to the given normal disc.

§ discFromArc()

void regina::DiscSetTet::discFromArc	(	int	arcFace,
		int	arcVertex,
		unsigned long	arcNumber,
		int &	discType,
		unsigned long &	discNumber
	)		const

inherited

Determines which normal disc in this tetrahedron meets the given normal arc on the given face.

Precondition: The given normal arc actually exists in the normal surface with which this DiscSetTet object was created.

Parameters

arcFace	the face of this tetrahedron containing the normal arc (between 0 and 3 inclusive).
arcVertex	the vertex of this tetrahedron about which the normal arc runs (between 0 and 3 inclusive); arcFace and arcVertex should not be the same.
arcNumber	indicates which normal arc of the given type is referred to. Arcs of a given type (where arcFace and arcVertex together define the arc type) are numbered starting at 0 from the tetrahedron vertex outwards.
discType	returns the disc type of the normal disc that meets the given normal arc; this will be between 0 and 9 inclusive, as described in the DiscSpec class notes. Any value may be initially passed.
discNumber	returns a number that indicates which normal disc of the returned disc type (`discType`) meets the given normal arc; this will be between 0 and `nDiscs(discType)-1` inclusive. Any value may be initially passed.

§ nDiscs()

unsigned long regina::DiscSetTet::nDiscs ( int type ) const

inlineinherited

Determines the number of discs of the given type inside this tetrahedron.

Parameters

type	the disc type to examine; this should be between 0 and 9 inclusive. Disc types are outlined in the DiscSpec class notes.

Returns: the number of discs of the given type inside this tetrahedron.
