Class StringNormalizeFunction

java.lang.Object
  com.sun.xacml.cond.FunctionBase
      com.sun.xacml.cond.StringNormalizeFunction

All Implemented Interfaces:

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

Field Summary

static String	NAME_STRING_NORMALIZE_SPACE Standard identifier for the string-normalize-space function.
static String	NAME_STRING_NORMALIZE_TO_LOWER_CASE Standard identifier for the string-normalize-to-lower-case function.

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
