  - ### getDebug

    public boolean getDebug()

  - ### setDebug

    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

  - ### getEmptyMethods

    public boolean getEmptyMethods()

  - ### setEmptyMethods

    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)

  - ### instantiateDelegateWithBaseClass

    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
