Class XPathFunctionContext

java.lang.Object
org.jaxen.SimpleFunctionContext
org.jaxen.XPathFunctionContext
All Implemented Interfaces:
FunctionContext
public class XPathFunctionContext extends SimpleFunctionContext
A FunctionContext implementing the core XPath function library, plus Jaxen extensions.

The core XPath function library is provided through this implementation of FunctionContext. Additionally, extension functions have been provided, as enumerated below.

This class is re-entrant and thread-safe. If using the default instance, it is inadvisable to call SimpleFunctionContext.registerFunction(String, String, Function) as that will extend the global function context, affecting other users.

Extension functions:

  • evaluate(..)
  • upper-case(..)
  • lower-case(..)
  • ends-with(..)
