Class StringNormalizeFunction

java.lang.Object

org.jboss.security.xacml.sunxacml.cond.FunctionBase

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.

Constructor Detail

StringNormalizeFunction

public StringNormalizeFunction(String functionName)

Creates a new StringNormalizeFunction object.

Parameters:

functionName - the standard XACML name of the function to be handled by this object, including the full namespace

Throws:

IllegalArgumentException - if the function is unknown

Method Detail

getSupportedIdentifiers

public static Set getSupportedIdentifiers()

Returns a Set containing all the function identifiers supported by this class.

Returns:

a Set of Strings

evaluate

public EvaluationResult evaluate(List inputs,
                        EvaluationCtx context)

Evaluate the function, using the specified parameters.

Parameters:

inputs - a List of Evaluatable objects representing the arguments passed to the function

context - an EvaluationCtx so that the Evaluatable objects can be evaluated

Returns:

an EvaluationResult representing the function's result
