int | threadnb |
A thread which is being run. The periodicity is the time between the starting of two runs or zero for non periodic threads.

pure virtual |
Implemented in RTT::os::Thread, RTT::Activity, and RTT::os::MainThread.
|
pure virtual |
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Read the name of this task
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Get the periodicity in Seconds. Return zero if non periodic.
Implemented in RTT::os::Thread, RTT::extras::FileDescriptorActivity, RTT::Activity, and RTT::os::MainThread.
|
pure virtual |
Get the periodicity in nanoseconds. Return zero if non periodic.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Returns the Process or Thread ID of this thread, as assigned by the Operating System. This function tries to return the Thread ID, if the OS supports it, otherwise it returns the process ID. If that is not available either, zero is returned. On Linux systems for example, the Thread ID of the main thread is equal to the Process ID. The Thread ID of every newly created thread is different from the Process ID (and unique).
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
The priority of this Thread.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Get the scheduler policy in which this thread runs.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Get the RTOS_TASK pointer.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
const version of the above.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Returns whether the thread is active. A thread is active between the invocation of start() and the invocation of stop().
Implemented in RTT::os::Thread, RTT::Activity, and RTT::os::MainThread.
|
pure virtual |
Returns whether the thread is running. A thread is running if it is executing its loop() function or in the process of periodically calling step(). Hence for periodic threads, isRunning() == isActive() while for non-periodic threads, isRunning() is only true if isActive() and it is executing loop().
Implemented in RTT::os::Thread, RTT::extras::FileDescriptorActivity, RTT::Activity, RTT::os::MainThread, and RTT::extras::SimulationThread.

|
pure virtual |
Set the periodicity in Seconds.
new_period | A positive number expressing the period |
Implemented in RTT::extras::FileDescriptorActivity, RTT::Activity, RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Set the priority of this Thread.
priority | The priority given upon construction of this thread. It has to be interpreted in the current OS scheduler. |
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Change the scheduler policy in which this thread runs.
sched_type | An OS-specific value which selects a scheduler. Orocos requires that these two values are available:
|
Your OS can in addition provide other sched_type's which map more naturally to the schedulers present. If your OS does not make a distinction between real-time and other, both values may map to the same scheduler type.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|
pure virtual |
Set the wait policy of a periodic thread
The | wait policy can be ORO_WAIT_ABS (absolute wait) and ORO_WAIT_REL (relative wait, with respect to current time) |
Implemented in RTT::os::Thread, RTT::Activity, and RTT::os::MainThread.
|
pure virtual |
Start the Thread.
Implemented in RTT::extras::FileDescriptorActivity, RTT::Activity, RTT::os::Thread, RTT::extras::IRQActivity, RTT::extras::SimulationThread, and RTT::os::MainThread.
|
pure virtual |
Stop the Thread.
Implemented in RTT::extras::FileDescriptorActivity, RTT::Activity, RTT::os::Thread, and RTT::os::MainThread.
|
inline |
The unique thread number (within the same process).
Definition at line 217 of file ThreadInterface.hpp.
|
pure virtual |
Yields (put to the back of the scheduler queue) the calling thread.
Implemented in RTT::os::Thread, and RTT::os::MainThread.
|

Threads are given an unique number, which follows thread creation order.
