- org.springframework.context.weaving.DefaultContextLoadTimeWeaver

All Implemented Interfaces:
Aware, BeanClassLoaderAware, DisposableBean, LoadTimeWeaver
```
public class DefaultContextLoadTimeWeaver
extends Object
implements LoadTimeWeaver, BeanClassLoaderAware, DisposableBean
```
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. As of Spring Framework 5.0, it detects Oracle WebLogic 10+, GlassFish 4+, Tomcat 8+, WildFly 8+, IBM WebSphere 8.5+, Spring's VM agent, and any ClassLoader supported by Spring's ReflectiveLoadTimeWeaver (such as Liberty's).

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`addTransformer(ClassFileTransformer transformer)`	Add a `ClassFileTransformer` to be applied by this `LoadTimeWeaver`.
`protected LoadTimeWeaver`	`createServerSpecificLoadTimeWeaver(ClassLoader classLoader)`
`void`	`destroy()`	Invoked by the containing `BeanFactory` on destruction of a bean.
`ClassLoader`	`getInstrumentableClassLoader()`	Return a `ClassLoader` that supports instrumentation through AspectJ-style load-time weaving based on user-defined `ClassFileTransformers`.
`ClassLoader`	`getThrowawayClassLoader()`	Return a throwaway `ClassLoader`, enabling classes to be loaded and inspected without affecting the parent `ClassLoader`.
`void`	`setBeanClassLoader(ClassLoader classLoader)`	Callback that supplies the bean `class loader` to a bean instance.

```
public void setBeanClassLoader(ClassLoader classLoader)
```
    Description copied from interface: BeanClassLoaderAware
    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'sInitializingBean.afterPropertiesSet() method or a custom init-method.
    Specified by:
    setBeanClassLoader in interface BeanClassLoaderAware
    Parameters:
    classLoader - the owning class loader
  - createServerSpecificLoadTimeWeaver
```
@Nullable
protected LoadTimeWeaver createServerSpecificLoadTimeWeaver(ClassLoader classLoader)
```
  - destroy
```
public void destroy()
```
    Description copied from interface: DisposableBean
    Invoked by the containing BeanFactory on destruction of a bean.
    Specified by:
    destroy in interface DisposableBean
  - addTransformer
```
public void addTransformer(ClassFileTransformer transformer)
```
    Description copied from interface: LoadTimeWeaver
    Add a ClassFileTransformer to be applied by this LoadTimeWeaver.
    Specified by:
    addTransformer in interface LoadTimeWeaver
    Parameters:
    transformer - the ClassFileTransformer to add
  - getInstrumentableClassLoader
```
public ClassLoader getInstrumentableClassLoader()
```
    Description copied from interface: LoadTimeWeaver
    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.
    Specified by:
    getInstrumentableClassLoader in interface LoadTimeWeaver
    Returns:
    the ClassLoader which will expose instrumented classes according to the registered transformers
  - getThrowawayClassLoader
```
public ClassLoader getThrowawayClassLoader()
```
    Description copied from interface: LoadTimeWeaver
    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 LoadTimeWeaver.getInstrumentableClassLoader().
    Specified by:
    getThrowawayClassLoader in interface LoadTimeWeaver
    Returns:
    a temporary throwaway ClassLoader; should return a new instance for each call, with no existing state
