All Implemented Interfaces:
LoadTimeWeaver
```
public class SimpleLoadTimeWeaver
extends Object
implements LoadTimeWeaver
```
LoadTimeWeaver that builds and exposes a SimpleInstrumentableClassLoader.
Mainly intended for testing environments, where it is sufficient to perform all class transformation on a newly created ClassLoader instance.
Since:
2.0

  - getInstrumentableClassLoader
```
public ClassLoader getInstrumentableClassLoader()
```
    Description copied from interface: 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.
    Specified by:
    getInstrumentableClassLoader in interface LoadTimeWeaver
    Returns:
    the ClassLoader which will expose instrumented classes according to the registered transformers
  - getThrowawayClassLoader
```
public ClassLoader getThrowawayClassLoader()
```
    This implementation builds a SimpleThrowawayClassLoader.
    Specified by:
    getThrowawayClassLoader in interface LoadTimeWeaver
    Returns:
    a temporary throwaway ClassLoader; should return a new instance for each call, with no existing state
