Default LoadTimeWeaver bean for use in an application context, decorating an automatically detected internal LoadTimeWeaver.

Typically registered for the default bean name "loadTimeWeaver"; the most convenient way to achieve this is Spring's <context:load-time-weaver> XML tag or @EnableLoadTimeWeaving on a @Configuration class.

This class implements a runtime environment check for obtaining the appropriate weaver implementation, including Spring's VM agent and any ClassLoader supported by Spring's ReflectiveLoadTimeWeaver.

the ClassFileTransformer to add
transformer)

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

Add a ClassFileTransformer to be applied by this LoadTimeWeaver.
protected LoadTimeWeaver
createServerSpecificLoadTimeWeaver(ClassLoader classLoader)

public void
destroy()

Implements org.springframework.beans.factory.DisposableBean.destroy.

Invoked by the containing BeanFactory on destruction of a bean.
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.

Return a throwaway ClassLoader, enabling classes to be loaded and inspected without affecting the parent ClassLoader.

public ClassLoader getInstrumentableClassLoader()

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

Doc from org.springframework.instrument.classloading.LoadTimeWeaver.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:ClassLoader

the ClassLoader which will expose instrumented classes according to the registered transformers

public ClassLoader getThrowawayClassLoader()

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

Doc from org.springframework.instrument.classloading.LoadTimeWeaver.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:ClassLoader

a temporary throwaway ClassLoader; should return a new instance for each call, with no existing state

setBeanClassLoaderback to summary
public void setBeanClassLoader(ClassLoader classLoader)

Implements org.springframework.beans.factory.BeanClassLoaderAware.setBeanClassLoader.

Doc from org.springframework.beans.factory.BeanClassLoaderAware.setBeanClassLoader.

Callback that supplies the bean class loader to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's InitializingBean#afterPropertiesSet() method or a custom init-method.

Parameters
classLoader:ClassLoader

the owning class loader
