Detailed Description

This thread is the simulated real-time periodic thread in the Orocos system.

All your activities in the same program must be a SimulationActivity for this to work, since the os::TimeService global time is updated when this thread runs.

By default, the update period is 0.001 seconds. If you want to run with a finer or coarser grained time step, use the Instance() method and supply another period before SimulationActivities are created.

Note:: This implementation has lost the capability to run SimulationActivity objects of different periods.

void RTT::SimulationThread::finalize ( ) [protected, virtual]

See also:: base::RunnableInterface::finalize()

Reimplemented from RTT::extras::TimerThread.

Definition at line 155 of file SimulationThread.cpp.

bool RTT::SimulationThread::initialize ( ) [protected, virtual]

See also:: base::RunnableInterface::initialize()

Reimplemented from RTT::extras::TimerThread.

Definition at line 141 of file SimulationThread.cpp.

SimulationThreadPtr RTT::SimulationThread::Instance ( double period = 0.001 ) [static]

Create the SimulationThread with a given period. Only one SimulationThread can be created.

Parameters:

period

The period in seconds at which the simulation takes steps and updates the TimeService. Only the first invocation of Instance will consider this parameter. The others will ignore it.

Definition at line 69 of file SimulationThread.cpp.

bool RTT::SimulationThread::isRunning ( ) const [virtual]

Returns true if thread is running or run( unsigned int ) is being invoked.

Reimplemented from RTT::os::Thread.

Definition at line 103 of file SimulationThread.cpp.

bool RTT::SimulationThread::Release ( ) [static]

Releases the SimulationThread Reference counting might aid in making this call safe

Returns:: true on success, false on failure

Definition at line 79 of file SimulationThread.cpp.

bool RTT::SimulationThread::run ( unsigned int maxsteps ) [virtual]

Execute maxsteps steps immediately. This function will call the step() functions maxsteps times, without requiring start() or stop() to be called before or after. The thread is thus not used.
