Constructors

<init>

 InstrumentationSavingAgent()

Java agent that saves the Instrumentation interface from the JVM for later use.

Functions

agentmain

 open static fun agentmain(agentArgs: String, inst: Instrumentation): Unit

Save the Instrumentation interface exposed by the JVM. This method is required to dynamically load this Agent with the Attach API.

getInstrumentation

 open static fun getInstrumentation(): Instrumentation

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.

premain

 open static fun premain(agentArgs: String, inst: Instrumentation): Unit

Save the Instrumentation interface exposed by the JVM.
