extends Object
implements LoadTimeWeaver
Class Inheritance
All Implemented Interfaces
org.springframework.instrument.classloading.LoadTimeWeaver
Imports
java.lang.instrument.ClassFileTransformer, org.springframework.util.Assert, .ClassUtils
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.
