Class FunctionTable

  +--weblogic.apache.xpath.compiler.FunctionTable

public class FunctionTable

extends java.lang.Object

The function table for XPath.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Obtain a new Function object from a function ID.

Parameters:

which - The function ID, which may correspond to one of the FUNC_XXX values found in FunctionTable, but may be a value installed by an external module.

Returns:

a a new Function instance.

Throws:

javax.xml.transform.TransformerException - if ClassNotFoundException, IllegalAccessException, or InstantiationException is thrown.
