Constructor Detail

ConditionSetFunction

public ConditionSetFunction(String functionName)
Constructor that is used to create one of the condition standard set functions. The name supplied must be one of the standard XACML functions supported by this class, including the full namespace, otherwise an exception is thrown. Look in SetFunction for details about the supported names.

Parameters:
functionName - the name of the function to create
Throws:
IllegalArgumentException - if the function is unknown

ConditionSetFunction

public ConditionSetFunction(String functionName,
                            String datatype,
                            String functionType)
Constructor that is used to create instances of condition set functions for new (non-standard) datatypes. This is equivalent to using the getInstance methods in SetFunction and is generally only used by the run-time configuration code.

Parameters:
functionName - the name of the new function
datatype - the full identifier for the supported datatype
functionType - which kind of Set function, based on the NAME_BASE_* fields
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)
Evaluates 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
