Re: [Gems-users] Regd using externally declared enumerations in the slicc files

[Mike Marty <mikem@xxxxxxxxxxx>]

Yes.  Create a class that inherits from Consumer and implement the
wakeup() method.

If the system has a single instance of your module, you can instantiate
your class in the ruby/System.h class by simply adding it as a private
member variable.

Here is an example of something similar I did not to long ago that wakes
up every TIMER_PERIOD and calls g_system_ptr->triggerTimeout()

MyTimer.h
-----------------

class MyTimer : public Consumer {
public:
  MyTimer();
  void wakeup();
};

MyTimer.C
---------------------

#include "MyTimer.h"
#include "System.h"

MyTimer::MyTimer()
{
  g_eventQueue_ptr->scheduleEvent(this, TIMER_PERIOD);
}

void MyTimer::wakeup()
{
  g_eventQueue_ptr->scheduleEvent(this, TIMER_PERIOD);
  g_system_ptr->triggerTimeout();
}
