All Implemented Interfaces:
Function

public class ModFunction
extends FunctionBase

A class that implements the integer-mod function. It takes two integer operands and returns the remainder. If either of the operands is indeterminate, an indeterminate result is returned.

Since:
1.0

Constructor Detail

ModFunction

public ModFunction(String functionName)
Creates a new ModFunction 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
