Member Function Documentation

run()

void fakeNavigationThread::run ( )

overridevirtual

Loop function.

This is the thread itself. The thread calls the run() function every <period> ms. At the end of each run, the thread will sleep the amounth of time required, taking into account the time spent inside the loop function. Example: requested period is 10ms, the run() function take 3ms to be executed, the thread will sleep for 7ms.

Note: after each run is completed, the thread will call a yield() in order to facilitate other threads to run.

Implements yarp::os::PeriodicThread.

threadInit()

bool fakeNavigationThread::threadInit ( )

overridevirtual

Initialization method.

The thread executes this function when it starts and before "run". This is a good place to perform initialization tasks that need to be done by the thread itself (device drivers initialization, memory allocation etc). If the function returns false the thread quits and never calls "run". The return value of threadInit() is notified to the class and passed as a parameter to afterStart(). Note that afterStart() is called by the same thread that is executing the "start" method.

Reimplemented from yarp::os::PeriodicThread.

Definition at line 177 of file fakeNavigationDev.cpp.

threadRelease()

void fakeNavigationThread::threadRelease ( )

overridevirtual

Release method.

The thread executes this function once when it exits, after the last "run". This is a good place to release resources that were initialized in threadInit() (release memory, and device driver resources).

Reimplemented from yarp::os::PeriodicThread.
