- - ### Field Detail

    - #### INSTANCE

          public static final ProxyGenerator INSTANCE

  - ### Constructor Detail

    - #### ProxyGenerator

          public ProxyGenerator()

  - ### Method Detail

    - #### 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

      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
