## org.springframework.instrument.classloading
Class SimpleLoadTimeWeaver

    java.lang.Object
      org.springframework.instrument.classloading.SimpleLoadTimeWeaver

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
Author:
  Rod Johnson, Juergen Hoeller

  `getInstrumentableClassLoader()`, `SimpleInstrumentableClassLoader`, `ReflectiveLoadTimeWeaver`

Constructor Summary
`SimpleLoadTimeWeaver()` Create a new SimpleLoadTimeWeaver for the current context class loader.
`SimpleLoadTimeWeaver(SimpleInstrumentableClassLoader classLoader)` Create a new SimpleLoadTimeWeaver for the given class loader.

Method Summary
`void` | `addTransformer(ClassFileTransformer transformer)` Add a class file transformer to be applied by this load-time weaver.
`ClassLoader` | `getInstrumentableClassLoader()` Return a class loader that supports instrumentation through AspectJ-style load-time weaving based on user-defined `ClassFileTransformers`.
`ClassLoader` | `getThrowawayClassLoader()` This implementation builds a `SimpleThrowawayClassLoader`.

    `addTransformer` in interface `LoadTimeWeaver`
  Parameters:
    `transformer` - the class file transformer to add

### getInstrumentableClassLoader

    public ClassLoader getInstrumentableClassLoader()

  Description copied from interface: `LoadTimeWeaver`
  Return a class loader that supports instrumentation through AspectJ-style load-time weaving based on user-defined `ClassFileTransformers`.

  May be the current class loader, or a class loader created by this `LoadTimeWeaver` instance.

  Specified by:
    `getInstrumentableClassLoader` in interface `LoadTimeWeaver`

    a class loader that supports instrumentation through AspectJ-style load-time weaving based on user-defined `ClassFileTransformers`

### getThrowawayClassLoader

    public ClassLoader getThrowawayClassLoader()

  This implementation builds a `SimpleThrowawayClassLoader`.

  Specified by:
    `getThrowawayClassLoader` in interface `LoadTimeWeaver`
  Returns:
    a temporary throwaway class loader; should return a new instance for each call, with no existing state
