[Java] Class IndyInterface
- 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.

Method Detail
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
- Since:
- Groovy 2.1.0
