- 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.
- Since:
- 1.2
getSupportedFunctions
public java.util.Set 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.
