Constructor Detail

GeneralSetFunction

public GeneralSetFunction(java.lang.String functionName)

Constructor that is used to create one of the general-purpose 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.

---

GeneralSetFunction

public GeneralSetFunction(java.lang.String functionName,
                          java.lang.String datatype,
                          java.lang.String functionType)

Constructor that is used to create instances of general-purpose 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.

Method Detail

getId

private static int getId(java.lang.String functionName)

Private helper that returns the internal identifier used for the given standard function.

---

getArgumentType

private static java.lang.String getArgumentType(java.lang.String functionName)

Private helper that returns the argument type for the given standard function. Note that this doesn't check on the return value since the method always is called after getId, so we assume that the function is present.

---

getSupportedIdentifiers

public static java.util.Set getSupportedIdentifiers()

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

---

evaluate

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

Evaluates the function, using the specified parameters.
