Creates a new instance of a MapFunction.

Method Detail

getSupportedIdentifiers

public static java.util.Set getSupportedIdentifiers()

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

---

getInstance

public static MapFunction getInstance(org.w3c.dom.Node root)
                               throws com.sun.xacml.ParsingException

---

getIdentifier

public java.net.URI getIdentifier()

Returns the full identifier of this function, as known by the factories.

Specified by:

getIdentifier in interface Function

---

getReturnType

public java.net.URI getReturnType()

Returns the attribute type returned by this function.

Specified by:

getReturnType in interface Function

---

returnsBag

public boolean returnsBag()

Returns true, since the map function always returns a bag

Specified by:

returnsBag in interface Function

---

makeProcessingError

private static EvaluationResult makeProcessingError(java.lang.String message)

Helper function to create a processing error message.

---

evaluate

public EvaluationResult evaluate(java.util.List inputs,
                                 com.sun.xacml.EvaluationCtx context)

Evaluates the function given the input data. Map expects a Function followed by a BagAttribute.

Specified by:

evaluate in interface Function

---

checkInputs

public void checkInputs(java.util.List inputs)
                 throws java.lang.IllegalArgumentException

Checks that the input list is valid for evaluation.

Specified by:

checkInputs in interface Function

---

checkInputsNoBag

public void checkInputsNoBag(java.util.List inputs)
                      throws java.lang.IllegalArgumentException

Always throws IllegalArgumentException since map needs to work on a bag

Specified by:

checkInputsNoBag in interface Function
