org.codehaus.groovy.vmplugin.v7.IndyInterface
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.

    • bootstrap

      public static CallSite bootstrap(MethodHandles.Lookup caller, String callType, MethodType type, String name, int flags)
      bootstrap method for method calls from Groovy compiled code with indy enabled. This method gets a flags parameter which uses the following encoding:
      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
