java.lang.Object

java.lang.Enum<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe>

net.bytebuddy.agent.builder.AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe

All Implemented Interfaces:

Serializable, Comparable<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe>, java.lang.constant.Constable, AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

Enclosing interface:

AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

public static enum AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe
extends Enum<AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader.UsingUnsafe>
implements AgentBuilder.LambdaInstrumentationStrategy.LambdaMetafactoryFactory.Loader

A loader that is using unsafe API to load a lambda implementation. The code for loading the class looks similar to the following:

Unsafe unsafe = Unsafe.getUnsafe();
Class<?> lambdaClass = unsafe.defineAnonymousClass(caller.lookupClass(),
  binaryRepresentation,
  null);
unsafe.ensureClassInitialized(lambdaClass);
