所有已实现的接口:
LoadTimeWeaver
```
public class ReflectiveLoadTimeWeaver
extends Object
implements LoadTimeWeaver
```
LoadTimeWeaver which uses reflection to delegate to an underlying ClassLoader with well-known transformation hooks. The underlying ClassLoader is expected to support the following weaving methods (as defined in the LoadTimeWeaver interface):
- public void addTransformer(java.lang.instrument.ClassFileTransformer): for registering the given ClassFileTransformer on this ClassLoader
- public ClassLoader getThrowawayClassLoader(): for obtaining a throwaway class loader for this ClassLoader (optional; ReflectiveLoadTimeWeaver will fall back to a SimpleThrowawayClassLoader if that method isn't available)
Please note that the above methods must reside in a class that is publicly accessible, although the class itself does not have to be visible to the application's class loader.
The reflective nature of this LoadTimeWeaver is particularly useful when the underlying ClassLoader implementation is loaded in a different class loader itself (such as the application server's class loader which is not visible to the web application). There is no direct API dependency between this LoadTimeWeaver adapter and the underlying ClassLoader, just a 'loose' method contract.
This is the LoadTimeWeaver to use e.g. with the Resin application server version 3.1+.

构造器概要

构造器
构造器	说明
`ReflectiveLoadTimeWeaver()`	Create a new ReflectiveLoadTimeWeaver for the current context class loader, which needs to support the required weaving methods.
`ReflectiveLoadTimeWeaver(ClassLoader classLoader)`	Create a new SimpleLoadTimeWeaver for the given class loader.

修饰符和类型	方法	说明
`void`	`addTransformer(ClassFileTransformer transformer)`	Add a `ClassFileTransformer` to be applied by this `LoadTimeWeaver`.
`ClassLoader`	`getInstrumentableClassLoader()`	Return a `ClassLoader` that supports instrumentation through AspectJ-style load-time weaving based on user-defined `ClassFileTransformers`.
`ClassLoader`	`getThrowawayClassLoader()`	Return a throwaway `ClassLoader`, enabling classes to be loaded and inspected without affecting the parent `ClassLoader`.

  - getInstrumentableClassLoader
```
public ClassLoader getInstrumentableClassLoader()
```
    从接口复制的说明: LoadTimeWeaver
    Return a ClassLoader that supports instrumentation through AspectJ-style load-time weaving based on user-defined ClassFileTransformers.
    May be the current ClassLoader, or a ClassLoader created by this LoadTimeWeaver instance.
    指定者:
    getInstrumentableClassLoader 在接口中 LoadTimeWeaver
    返回:
    the ClassLoader which will expose instrumented classes according to the registered transformers
  - getThrowawayClassLoader
```
public ClassLoader getThrowawayClassLoader()
```
    从接口复制的说明: LoadTimeWeaver
    Return a throwaway ClassLoader, enabling classes to be loaded and inspected without affecting the parent ClassLoader.
    Should not return the same instance of the ClassLoader returned from an invocation of LoadTimeWeaver.getInstrumentableClassLoader().
    指定者:
    getThrowawayClassLoader 在接口中 LoadTimeWeaver
    返回:
    a temporary throwaway ClassLoader; should return a new instance for each call, with no existing state
