Class XPathException

Known Direct Subclasses:
XPathProcessorException

public class XPathException
extends TransformerException

This class implements an exception object that all XPath classes will throw in case of an error. This class extends TransformerException, and may hold other exceptions. In the case of nested exceptions, printStackTrace will dump all the traces of the nested exceptions, not just the trace of this object.

Constructor Summary

XPathException(String message)
Create an XPathException object that holds an error message.
XPathException(String message, Exception e)
Create an XPathException object that holds an error message, and another exception that caused this exception.
XPathException(String message, Object styleNode)
Create an XPathException object that holds an error message and the stylesheet node that the error originated from.
XPathException(String message, ExpressionNode ex)
Create an XPathException object that holds an error message.
XPathException(String message, Node styleNode, Exception e)
Create an XPathException object that holds an error message, the stylesheet node that the error originated from, and another exception that caused this exception.

Method Summary

Constructor Details

XPathException

public XPathException(String message)
Create an XPathException object that holds an error message.
Parameters:
message - The error message.

                      Exception e)
Create an XPathException object that holds an error message, and another exception that caused this exception.
Parameters:
message - The error message.
e - The exception that caused this exception.

XPathException

public XPathException(String message,
                      Object styleNode)
Create an XPathException object that holds an error message and the stylesheet node that the error originated from.
Parameters:
message - The error message.
styleNode - The stylesheet node that the error originated from.

XPathException

public XPathException(String message,
                      ExpressionNode ex)

                      Exception e)
Create an XPathException object that holds an error message, the stylesheet node that the error originated from, and another exception that caused this exception.
Parameters:
message - The error message.
styleNode - The stylesheet node that the error originated from.

Method Details

getException

public Throwable getException()
Return the embedded exception, if any. Overrides javax.xml.transform.TransformerException.getException().
Overrides:
getException in interface TransformerException
Returns:
The embedded exception, or null if there is none.

getMessage

public String getMessage()
Find the most contained message.
Returns:
The error message of the originating exception.

getStylesheetNode

public Object getStylesheetNode()
Get the stylesheet node from where this error originated.
Returns:
The stylesheet node from where this error originated, or null.

getStylesheetNode

public Node getStylesheetNode(ExpressionNode ex)
Get the XSLT ElemVariable that this sub-expression references. In order for this to work, the SourceLocator must be the owning ElemTemplateElement.
Returns:
The dereference to the ElemVariable, or null if not found.

printStackTrace

public void printStackTrace(java.io.PrintStream s)
Print the the trace of methods from where the error originated. This will trace all nested exception objects, as well as this object.
Overrides:
printStackTrace in interface TransformerException
Parameters:
s - The stream where the dump will be sent to.

printStackTrace

public void printStackTrace(java.io.PrintWriter s)
Print the the trace of methods from where the error originated. This will trace all nested exception objects, as well as this object.
Overrides:
printStackTrace in interface TransformerException
Parameters:
s - The writer where the dump will be sent to.

setStylesheetNode

public void setStylesheetNode(Object styleNode)
Set the stylesheet node from where this error originated.
Parameters:
styleNode - The stylesheet node from where this error originated, or null.
