- org.springframework.instrument.classloading.jboss.JBossLoadTimeWeaver

All Implemented Interfaces:
LoadTimeWeaver
```
public class JBossLoadTimeWeaver
extends Object
implements LoadTimeWeaver
```
LoadTimeWeaver implementation for JBoss's instrumentable ClassLoader. Autodetects the specific JBoss version at runtime: currently supports JBoss AS 6 and 7, as well as WildFly 8 and 9 (as of Spring 4.2).
NOTE: On JBoss 6, to avoid the container loading the classes before the application actually starts, one needs to add a WEB-INF/jboss-scanning.xml file to the application archive - with the following content:
```
<scanning xmlns="urn:jboss:scanning:1.0"/>
```
Thanks to Ales Justin and Marius Bogoevici for the initial prototype.
Since:
3.0

Constructor Summary

Constructors
Constructor	Description
`JBossLoadTimeWeaver()`	Create a new instance of the `JBossLoadTimeWeaver` class using the default `class loader`.
`JBossLoadTimeWeaver(ClassLoader classLoader)`	Create a new instance of the `JBossLoadTimeWeaver` class using the supplied `ClassLoader`.

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`.
`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`.

```
public JBossLoadTimeWeaver()
```
    Create a new instance of the JBossLoadTimeWeaver class using the default class loader.

    ClassUtils.getDefaultClassLoader()
  - JBossLoadTimeWeaver
```
public JBossLoadTimeWeaver(ClassLoader classLoader)
```
    Create a new instance of the JBossLoadTimeWeaver class using the supplied ClassLoader.
    Parameters:
    classLoader - the ClassLoader to delegate to for weaving (must not be null)

  - 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
