public XPathException(String message)

Creates a new XPathException with a detail message.

XPathException

public XPathException(String message,
                      Throwable cause)

Creates a new IllegalNameException with a detail message and an underlying root cause.

Parameters:

Method Detail

getCause

public Throwable getCause()

Return the original cause that led to this exception, or null if there was no original exception.

Overrides:
getCause in class Throwable
Returns:
the root cause of this exception

initCause

public Throwable initCause(Throwable cause)

Sets the root cause of this exception. This may only be called once. Subsequent calls throw an IllegalStateException.

This method is unnecessary in Java 1.4 where it could easily be inherited from the superclass. However, including it here allows this method to be used in Java 1.3 and earlier.

Overrides:
initCause in class Throwable
Parameters:
cause - the root cause of this exception
Returns:
this XMLException
Throws:
IllegalArgumentException - if the cause is this exception (An exception cannot be its own cause.)
IllegalStateException - if this method is called twice

getXPath

public String getXPath()

Returns the specific XPath expression being evaluated when this excepiton was thrown.

Returns:
the XPath expression that caused the exception
