SunTM's XACML Implementation for JavaTM

Interface FunctionProxy

All Known Implementing Classes:

public interface FunctionProxy

Used by abstract functions to define how new functions are created by the factory. Note that all functions using XPath are defined to be abstract functions, so they must be created using this interface.


Method Summary

          Creates an instance of some abstract function.

public Function getInstance(Node root,
                            String xpathVersion)
                     throws Exception
