Class MapBuiltinRegistry

  • public class MapBuiltinRegistry
extends BuiltinRegistry
    A registry for mapping functor names on java objects (instances of subclasses of Builtin) which implement their behaviour.

    This is currently implemented as a singleton to simply any future move to support different sets of builtins.

        register in class BuiltinRegistry
        Parameters:
        functor - the name of the functor used to invoke the builtin
