Constructor Detail

StringConversionFunction

public StringConversionFunction(String functionName)

Creates a new EqualFunction object.

Parameters:

functionName - the standard XACML name of the function to be handled by this object, including the full namespace

Method Detail

getSupportedIdentifiers

public static Set<String> getSupportedIdentifiers()

Returns a Set containing all the function identifiers supported by this class.

Returns:

a Set of Strings

evaluate

public EvaluationResult evaluate(List<Evaluatable> inputs,
                                 EvaluationCtx context)

Description copied from interface: Function

Evaluates the Function using the given inputs. The List contains Evaluatables which are all of the correct type if the Function has been created as part of an Apply or TargetMatch, but which may otherwise be invalid. Each parameter should be evaluated by the Function, unless the Function doesn't need to evaluate all inputs to determine a result (as in the case of the or function). The order of the List is significant, so a Function should have a very good reason if it wants to evaluate the inputs in a different order.

Note that if this is a higher-order function, like any-of, then some argument (typically the first) in the List will actually be a Function object representing the function to apply to some bag. A function needs to know if it's a higher-order function, and therefore whether or not to look for this case. Also, a higher-order function is responsible for checking that the inputs that it will pass to the Function provided as the first parameter are valid, ie. it must do a checkInputs on its sub-function when checkInputs is called on the higher-order function.

Parameters:

inputs - the List of inputs for the function

context - the representation of the request

Returns:

a result containing the AttributeValue computed when evaluating the function, or Status specifying some error condition
