    - #### @SuppressWarnings("unchecked") public GroovyObject instantiateDelegateWithBaseClass(Map closureMap, List<Class> interfaces, Object delegate, Class baseClass, String name)

      Creates a proxy with a delegate object.

      Parameters:
        `closureMap` - the closure for methods not handled by the delegate
        `interfaces` - interfaces to be implemented
        `delegate` - the delegate object
        `baseClass` - the base class
        `name` - the name of the proxy, unused, but kept for compatibility with previous versions of Groovy.
      Returns:
        a proxy object implementing the specified interfaces, and delegating to the provided object

    - #### public void setDebug(boolean debug)

      Instructs `ProxyGenerator` to dump generated Groovy source code to standard output during construction. This is useful for debugging purposes but should be turned off in production.

      Parameters:
        `debug` - true if you want generated source to be printed

    - #### public void setEmptyMethods(boolean emptyMethods)

      Changes generated methods to have empty implementations.

      Methods in generated aggregates not supplied in a closures map or base class are given 'default' implementations. The implementation will normally throw an `UnsupportedOperationException` but setting this boolean will leave it empty.

      Parameters:
        `emptyMethods` - true if you want generated methods to be empty

    - #### public void setOverride(ClassLoader override)
