public static enum AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup extends java.lang.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();

values
public static AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup c : AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingMethodHandleLookup valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
