Constructor Detail

ConditionBagFunction

public ConditionBagFunction(String functionName)

Constructor that is used to create one of the condition standard bag 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 BagFunction for details about the supported names.

Parameters:

functionName - the name of the function to create

Throws:

IllegalArgumentException - if the function is unknown

ConditionBagFunction

public ConditionBagFunction(String functionName,
                            String datatype)

Constructor that is used to create instances of condition bag functions for new (non-standard) datatypes. This is equivalent to using the getInstance methods in BagFunction 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

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
