    • Method Detail

      • setInstrumentation

        public static void setInstrumentation​(Instrumentation inst)
        This method is not synchronized because when the agent is loaded from getInstrumentation() that method will cause agentmain(..) to be called. Synchronizing this method would cause a deadlock.
        Parameters:
        inst - The instrumentation instance to be used by this factory.
      • setDynamicallyInstallAgent

        public static void setDynamicallyInstallAgent​(boolean val)
        Configures whether or not this instance should attempt to dynamically install an agent in the VM. Defaults to true.
      • getInstrumentation

        public static Instrumentation getInstrumentation​(Log log)
        Parameters:
        log - OpenJPA log.
        Returns:
        null if Instrumentation can not be obtained, or if any Exceptions are encountered.
      • agentmain

        public static void agentmain​(String agentArgs,
                                     Instrumentation inst)
        The method that is called when a jar is added as an agent at runtime. All this method does is store the Instrumentation for later use.
