InstrumentationSavingAgent
public InstrumentationSavingAgent()
premain
public static void premain(String agentArgs,
Instrumentation inst)
- Save the
Instrumentation
interface exposed by the JVM.
getInstrumentation
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
InstrumentationLoadTimeWeaver.getInstrumentation()
instead - which will work without the agent class in the classpath as well.
- Returns:
- the
Instrumentation
instance previously saved when
the premain(java.lang.String, java.lang.instrument.Instrumentation)
method was called by the JVM; will be null
if this class was not used as Java agent when this JVM was started. - See Also:
