public static enum AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup
extends Enum<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup>
implements AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader
A loader that uses a method handle lookup object to load a class. This is implemented as follows:
MethodHandleInfo info = caller.revealDirect(implementation); boolean classData = (Modifier.isProtected(info.getModifiers())&&
!VerifyAccess.isSamePackage(caller.lookupClass(), info.getDeclaringClass())) || info.getReferenceKind() == Opcodes.H_INVOKESPECIAL; MethodHandles.Lookup lookup; if (classData) { lookup = caller.defineHiddenClassWithClassData(binaryRepresentation, info, true, MethodHandles.Lookup.ClassOption.NESTMATE, MethodHandles.Lookup.ClassOption.STRONG); } else { lookup = caller.defineHiddenClass(binaryRepresentation, true, MethodHandles.Lookup.ClassOption.NESTMATE, MethodHandles.Lookup.ClassOption.STRONG); }Class<?>
lambdaClass = lookup.lookupClass();
