initCause

public WebSocketHandshakeException initCause(Throwable cause)

Description copied from class: java.lang.Throwable

Initializes the cause of this throwable to the specified value. (The cause is the throwable that caused this throwable to get thrown.)

This method can be called at most once. It is generally called from within the constructor, or immediately after creating the throwable. If this throwable was created with Throwable(Throwable) or Throwable(String,Throwable), this method cannot be called even once.

An example of using this method on a legacy throwable type without other support for setting the cause is:

 try {
     lowLevelOp();
 } catch (LowLevelException le) {
     throw (HighLevelException)
           new HighLevelException().initCause(le); // Legacy constructor
 }
 

Overrides:

initCause in class Throwable

Parameters:

cause - the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Returns:

a reference to this Throwable instance.
