Member Function Documentation

virtual bool controller_interface::ControllerBase::initRequest	(	hardware_interface::RobotHW *	robot_hw,
		ros::NodeHandle &	root_nh,
		ros::NodeHandle &	controller_nh,
		ClaimedResources &	claimed_resources
	)		[pure virtual]

Request that the controller be initialized.

Parameters:

	robot_hw	The robot hardware abstraction.
	root_nh	A NodeHandle in the root of the controller manager namespace. This is where the ROS interfaces are setup (publishers, subscribers, services).
	controller_nh	A NodeHandle in the namespace of the controller. This is where the controller-specific configuration resides.
[out]	claimed_resources	The resources claimed by this controller. They can belong to multiple hardware interfaces.

Returns:

True if initialization was successful and the controller is ready to be started.

Implemented in controller_interface::MultiInterfaceController< T1, T2, T3, T4 >, and controller_interface::Controller< T >.

bool controller_interface::ControllerBase::isRunning

(

)

[inline]

Check if the controller is running.

Returns:

true if the controller is running

Definition at line 86 of file controller_base.h.

virtual void controller_interface::ControllerBase::starting

(

const ros::Time &

)

[inline, virtual]

This is called from within the realtime thread just before the first call to update.

Parameters:

time	The current time

Definition at line 67 of file controller_base.h.

bool controller_interface::ControllerBase::startRequest

(

const ros::Time &

time

)

[inline]

virtual void controller_interface::ControllerBase::stopping

(

const ros::Time &

)

[inline, virtual]

This is called from within the realtime thread just after the last update call before the controller is stopped.

Parameters:

time	The current time

Definition at line 81 of file controller_base.h.

bool controller_interface::ControllerBase::stopRequest

(

const ros::Time &

time

)

[inline]

Calls stopping only if this controller is initialized or already running.

Definition at line 112 of file controller_base.h.

virtual void controller_interface::ControllerBase::update	(	const ros::Time &	time,
		const ros::Duration &	period
	)		[pure virtual]

This is called periodically by the realtime thread when the controller is running.

Parameters:

time	The current time
period	The time passed since the last call to update

void controller_interface::ControllerBase::updateRequest	(	const ros::Time &	time,
		const ros::Duration &	period
	)		[inline]

Calls update only if this controller is running.

Definition at line 92 of file controller_base.h.
