Class ClassFileLocator.AgentBased

java.lang.Object

net.bytebuddy.dynamic.ClassFileLocator.AgentBased

All Implemented Interfaces:

ClassFileLocator

Enclosing interface:

ClassFileLocator

public static class ClassFileLocator.AgentBased
extends Object
implements ClassFileLocator

A Java agent that allows the location of class files by emulating a retransformation. Note that this class file locator causes a class to be loaded in order to look up its class file. Also, this locator does deliberately not support the look-up of classes that represent lambda expressions.
