Detailed Description

Consumer of notification about transition completeness in CSrvTransitionTask.

Virtual inheritance from CSrvTask is used to allow derived classes to combine several task types together (such as CSrvSocketTask, CSrvStatesTask etc.) and still have one implementation of CSrvTask.

Member Function Documentation

◆ IsTransFinished()

bool CSrvTransConsumer::IsTransFinished ( void  )

Check if transition completeness was consumed.

Derived classes must use this method (instead of CSrvTransitionTask::IsTransStateFinal()) because it returns TRUE not only when transition has been finished but also when this consumer was notified about that. Otherwise it will be possible that other thread finished transition and this thread will try to request transition on another task but it will unable to put this task to m_Consumers list as it wasn't removed from m_Consumers list of first task yet.
