Class StringNormalizeFunction

java.lang.Object

      extended by org.jboss.security.xacml.sunxacml.cond.StringNormalizeFunction
All Implemented Interfaces:
Expression, Function

public class StringNormalizeFunction
extends FunctionBase

A class that implements all the string conversion functions (string-normalize-space and string-normalize-to-lower-case). It takes string argument, normalizes that value, and returns the result. If the argument is indeterminate, an indeterminate result is returned.

Since:
1.0
