  • public class IndyInterface
    extends 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.

        Parameters:
        caller - - the caller
        callType - - the type of the call
        type - - the call site type
        name - - the real method name
        flags - - call flags
        Returns:
        the produced CallSite
