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.
| Constructor and 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. |
| Modifier and Type | Method and 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. |
