Class ContextDelegateFunctionFactory

  • All Implemented Interfaces:

    public class ContextDelegateFunctionFactory
    extends java.lang.Object
    implements FunctionFactory
    Many custom function factories get cached, but when delegating to the factory provided by the context, that shouldn't happen. This class can be used as the parent of those other factories, and will look up the context factory fresh each time.
