    Parameters:
    transformer - the ClassFileTransformer to add
  - getInstrumentableClassLoader
```
ClassLoader getInstrumentableClassLoader()
```
    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.
    Returns:
    the ClassLoader which will expose instrumented classes according to the registered transformers
  - getThrowawayClassLoader
```
ClassLoader getThrowawayClassLoader()
```
    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 getInstrumentableClassLoader().
    Returns:
    a temporary throwaway ClassLoader; should return a new instance for each call, with no existing state
