Public Methods

public static Instrumentation getInstrumentation ()

Return the Instrumentation interface exposed by the JVM.

Note that this agent class will typically not be available in the classpath unless the agent is actually specified on JVM startup. If you intend to do conditional checking with respect to agent availability, consider using org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver#getInstrumentation() instead - which will work without the agent class in the classpath as well.

Returns
  • the Instrumentation instance previously saved when the premain(String, Instrumentation) method was called by the JVM; will be null if this class was not used as Java agent when this JVM was started.
