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_hwThe robot hardware abstraction.
root_nhA NodeHandle in the root of the controller manager namespace. This is where the ROS interfaces are setup (publishers, subscribers, services).
controller_nhA NodeHandle in the namespace of the controller. This is where the controller-specific configuration resides.
[out]claimed_resourcesThe 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 82 of file controller_base.h.

ControllerBase& controller_interface::ControllerBase::operator= ( const ControllerBase c)
private
virtual void controller_interface::ControllerBase::starting ( const ros::Time )
inlinevirtual

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

Parameters
timeThe current time

Definition at line 63 of file controller_base.h.

bool controller_interface::ControllerBase::startRequest ( const ros::Time time)
inline

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

Definition at line 95 of file controller_base.h.

virtual void controller_interface::ControllerBase::stopping ( const ros::Time )
inlinevirtual

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

Parameters
timeThe current time

Definition at line 77 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 108 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
timeThe current time
periodThe 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 88 of file controller_base.h.
