Spring Context 6.1.4 · org.springframework.instrument.classloading.LoadTimeWeaver

Defines the contract for adding one or more ClassFileTransformers to a ClassLoader.

Implementations may operate on the current context ClassLoader or expose their own instrumentable ClassLoader.

Method Summary

Modifier and Type	Method and Description
public void	addTransformer(ClassFileTransformer the `ClassFileTransformer` to add transformer) Add a `ClassFileTransformer` to be applied by this `LoadTimeWeaver`.
public ClassLoader	Returns: the `ClassLoader` which will expose instrumented classes according to the registered transformers getInstrumentableClassLoader() Return a `ClassLoader` that supports instrumentation through AspectJ-style load-time weaving based on user-defined `ClassFileTransformers`.
public ClassLoader	Returns: a temporary throwaway `ClassLoader`; should return a new instance for each call, with no existing state getThrowawayClassLoader() Return a throwaway `ClassLoader`, enabling classes to be loaded and inspected without affecting the parent `ClassLoader`.
