Class PowerMockAgent

java.lang.Object

org.powermock.modules.agent.PowerMockAgent

public final class PowerMockAgent
extends java.lang.Object

This is the "agent class" that initializes the PowerMock "Java agent". It is not intended for use in client code. It must be public, however, so the JVM can call the premain method, which as the name implies is called before the main method.

premain

public static void premain(java.lang.String agentArgs,
                           java.lang.instrument.Instrumentation inst)
                    throws java.lang.Exception

This method must only be called by the JVM, to provide the instrumentation object. In order for this to occur, the JVM must be started with "-javaagent:powermock-module-javaagent-nnn.jar" as a command line parameter (assuming the jar file is in the current directory).

Throws:

java.lang.Exception

agentmain

public static void agentmain(java.lang.String agentArgs,
                             java.lang.instrument.Instrumentation inst)

Throws:

java.lang.Exception
