public interface FunctionCluster

Interface used by classes that support more than one function. It's a common design model to have a single class support more than one XACML function. In those cases, you should provide a proxy that implements FunctionCluster in addition to the Function. This is particularly important for the run-time configuration system, which uses this interface to create "clusters" of functions and therefore can use a smaller configuration file.

Method Summary

Modifier and Type	Method and Description
Set<Function>	getSupportedFunctions() Returns a single instance of each of the functions supported by some class.

Method Detail

getSupportedFunctions

Set<Function> getSupportedFunctions()

Returns a single instance of each of the functions supported by some class. The Set must contain instances of Function, and it must be both non-null and non-empty. It may contain only a single Function.

Note that this is only used to return concrete Functions. It may not be used to report abstract functions.

Returns:

the functions supported by this class
