Class IndyInterface

  • public class IndyInterface
extends java.lang.Object
    Bytecode level interface for bootstrap methods used by invokedynamic. This class provides a logging ability by using the boolean system property groovy.indy.logging. Other than that this class contains the interfacing methods with bytecode for invokedynamic as well as some helper methods and classes.
