the ClassLoader to delegate to for weaving
classLoader)

Create a new instance of the JBossLoadTimeWeaver class using the supplied ClassLoader.

Method Summary

Modifier and TypeMethod and Description
public void
addTransformer(ClassFileTransformer
the ClassFileTransformer to add
transformer)

Implements org.springframework.instrument.classloading.LoadTimeWeaver.addTransformer.

Add a ClassFileTransformer to be applied by this LoadTimeWeaver.
public ClassLoader
getInstrumentableClassLoader()

Implements org.springframework.instrument.classloading.LoadTimeWeaver.getInstrumentableClassLoader.

Return a ClassLoader that supports instrumentation through AspectJ-style load-time weaving based on user-defined ClassFileTransformers.
public ClassLoader
getThrowawayClassLoader()

Implements org.springframework.instrument.classloading.LoadTimeWeaver.getThrowawayClassLoader.
