Member Function Documentation

◆ clearAll()

bool FrameTransformSet_nwc_ros2::clearAll ( )

overridevirtual

Delete all transforms in a storage.

Returns: true/false

Implements yarp::dev::IFrameTransformStorageSet.

Definition at line 189 of file frameTransformSet_nwc_ros2.cpp.

◆ close()

bool FrameTransformSet_nwc_ros2::close ( )

overridevirtual

Close the DeviceDriver.

Returns: true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 48 of file frameTransformSet_nwc_ros2.cpp.

◆ deleteTransform()

bool FrameTransformSet_nwc_ros2::deleteTransform	(	std::string	src,
		std::string	dst
	)

overridevirtual

Delete a single transform in the storage.

Parameters

src	the source of frame transform to delete
dst	the destination of frame transform to delete

Returns: true/false

Implements yarp::dev::IFrameTransformStorageSet.

Definition at line 182 of file frameTransformSet_nwc_ros2.cpp.

◆ open()

bool FrameTransformSet_nwc_ros2::open ( yarp::os::Searchable & config )

overridevirtual

Open the DeviceDriver.

Parameters

config is a list of parameters for the device. Which parameters are effective for your device can vary. See device invocation examples. If there is no example for your device, you can run the "yarpdev" program with the verbose flag set to probe what parameters the device is checking. If that fails too, you'll need to read the source code (please nag one of the yarp developers to add documentation for your device).

Returns: true/false upon success/failure

Reimplemented from yarp::dev::DeviceDriver.

◆ publishFrameTransforms()

bool FrameTransformSet_nwc_ros2::publishFrameTransforms ( )

Definition at line 146 of file frameTransformSet_nwc_ros2.cpp.

◆ ros2TimeFromYarp()

void FrameTransformSet_nwc_ros2::ros2TimeFromYarp	(	double	yarpTime,
		builtin_interfaces::msg::Time &	ros2Time
	)

Definition at line 106 of file frameTransformSet_nwc_ros2.cpp.

◆ run()

void FrameTransformSet_nwc_ros2::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.

Parameters

transforms the transform to be stored

Returns: true/false

Implements yarp::dev::IFrameTransformStorageSet.
