java.lang.Objectorg.springframework.instrument.classloading.InstrumentationLoadTimeWeaver
public class InstrumentationLoadTimeWeaver
LoadTimeWeaver relying on VM Instrumentation.
 
Start the JVM specifying the Java agent to be used, like as follows:
-javaagent:path/to/spring-agent.jar
 
where spring-agent.jar is a JAR file containing the
 InstrumentationSavingAgent class.
 
In Eclipse, for example, set the "Run configuration"'s JVM args to be of the form:
-javaagent:${project_loc}/lib/spring-agent.jar

| InstrumentationLoadTimeWeaver()Create a new InstrumentationLoadTimeWeaver for the default ClassLoader. | |
| InstrumentationLoadTimeWeaver(ClassLoader classLoader)Create a new InstrumentationLoadTimeWeaver for the given ClassLoader. | |

|---|---|
|  void | addTransformer(ClassFileTransformer transformer)Add a ClassFileTransformerto be applied by thisLoadTimeWeaver. | 
|  ClassLoader | getInstrumentableClassLoader()We have the ability to weave the current class loader when starting the JVM in this way, so the instrumentable class loader will always be the current loader. | 
|  ClassLoader | getThrowawayClassLoader()This implementation always returns a SimpleThrowawayClassLoader. | 
| static boolean | isInstrumentationAvailable()Check whether an Instrumentation instance is available for the current VM. | 
|  void | removeTransformers()Remove all registered transformers, in inverse order of registration. |
