Detailed Description

template<class T>
class ProcessCreator< T >

The class is a helper that allows to instantiate a class as an Aperios process.

ProcessCreator contains the parts that need to be implemented as a template. It will only be used by the macro MAKE_PROCESS and should never be used directly.

Definition at line 231 of file ProcessFramework.h.

Constructor & Destructor Documentation

template<class T> ProcessCreator< T >::ProcessCreator (  const char *  name  )  [inline]

Constuctor. It is only called from MAKE_PROCESS. Parameters: name  The name of the process. Definition at line 359 of file ProcessFramework.h. References ProcessBase::init(), ProcessCreator< T >::lastTime, ProcessCreator< T >::process, and VERIFY.

Here is the call graph for this function:

Member Function Documentation

template<class T> virtual OStatus ProcessCreator< T >::DoInit (  const OSystemEvent &  event  )  [inline, private, virtual]

The function registers the global functions for object communication. It is called by OObject::Init(). Parameters: event  An Open-R event. Returns: The status. Currently, the function always reports success. Definition at line 244 of file ProcessFramework.h. References ASSERT, ENTRY_TABLE_MIN, SenderList::getName(), ReceiverList::getName(), SenderList::getNext(), ReceiverList::getNext(), ProcessCreator< T >::name, ProcessCreator< T >::process, ProcessBase::setBlockingId(), and VERIFY.

Here is the call graph for this function:

template<class T> virtual OStatus ProcessCreator< T >::DoStart (  const OSystemEvent &  event  )  [inline, private, virtual]

The function starts the process. It is called by OObject::Start(). Parameters: event  An Open-R event. Returns: The status. Currently, the function always reports success. Definition at line 283 of file ProcessFramework.h. References ReceiverList::getNext(), ProcessCreator< T >::process, and ProcessBase::setEventId().

Here is the call graph for this function:

template<class T> virtual OStatus ProcessCreator< T >::DoStop (  const OSystemEvent &  event  )  [inline, private, virtual]

The function stops the process. It is called by OObject::Stop(). However, OObject::Stop() is never called. Therefore, this function is called neither. Parameters: event  An Open-R event. Returns: The status. Currently, the function always reports success. Definition at line 299 of file ProcessFramework.h. References ReceiverList::getNext(), ProcessCreator< T >::process, and ProcessBase::stop().

Here is the call graph for this function:

template<class T> virtual OStatus ProcessCreator< T >::DoDestroy (  const OSystemEvent &  event  )  [inline, private, virtual]

The function destroys the process. It is called by OObject::Destroy(). However, OObject::Destroy() is never called. Therefore, this function is called neither. Parameters: event  An Open-R event. Returns: The status. Currently, the function always reports success. Definition at line 317 of file ProcessFramework.h.

template<class T> void ProcessCreator< T >::processNextFrame (   )  [inline, private, virtual]

The function is called once for each frame. It calls Process::main() and will start a timer if Process::main() returned a nonzero value. Implements ProcessBase. Definition at line 324 of file ProcessFramework.h. References SenderList::finishFrame(), SystemCall::getCurrentSystemTime(), PlatformProcess::getFirstReceiver(), PlatformProcess::getFirstSender(), ProcessCreator< T >::getProcess(), ProcessCreator< T >::lastTime, ProcessCreator< T >::process, ProcessBase::resetEventMask(), ProcessBase::setBlockingId(), and VERIFY.

Here is the call graph for this function:

template<class T> virtual PlatformProcess* ProcessCreator< T >::getProcess (   )  [inline, private, virtual]

The function returns the address of the associated process. Returns: The address of the object. Implements ProcessBase. Definition at line 351 of file ProcessFramework.h. References ProcessCreator< T >::process. Referenced by ProcessCreator< T >::processNextFrame().
