  - premain
```
public static void premain(String agentArgs,
                           Instrumentation inst)
```
    Save the Instrumentation interface exposed by the JVM.
  - agentmain
```
public static void agentmain(String agentArgs,
                             Instrumentation inst)
```
    Save the Instrumentation interface exposed by the JVM. This method is required to dynamically load this Agent with the Attach API.
  - 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.
    返回:
    the Instrumentation instance previously saved when the premain(java.lang.String, java.lang.instrument.Instrumentation) or agentmain(java.lang.String, java.lang.instrument.Instrumentation) methods was called by the JVM; will be null if this class was not used as Java agent when this JVM was started or it wasn't installed as agent using the Attach API.
