IndyInterface (groovy 2.4.15 API)

org.codehaus.groovy.vmplugin.v7.IndyInterface

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.

  - public static CallSite bootstrap(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:
    - {
      value:
      #SAFE_NAVIGATION} is the flag value for safe navigation see SAFE_NAVIGATION
      
      {@value #THIS_CALL} is the flag value for a call on this see THIS_CALL
    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
