Constructor Detail

ComparisonFunction

public ComparisonFunction(String functionName)

Creates a new ComparisonFunction 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 isn't known

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
