Member Function Documentation

◆ auto_declare()

template<typename ParameterT >

auto controller_interface::ControllerInterface::auto_declare	(	const std::string &	name,
		const ParameterT &	default_value
	)

inline

Declare and initialize a parameter with a type.

Wrapper function for templated node's declare_parameter() which checks if parameter is already declared. For use in all components that inherit from ControllerInterface

◆ command_interface_configuration()

virtual CONTROLLER_INTERFACE_PUBLIC InterfaceConfiguration controller_interface::ControllerInterface::command_interface_configuration ( ) const

pure virtual

Implemented in gripper_action_controller::GripperActionController< HardwareInterface >, and joint_trajectory_controller::JointTrajectoryController.

◆ configure()

const rclcpp_lifecycle::State & controller_interface::ControllerInterface::configure ( )

The methods below are a substitute to the LifecycleNode methods with the same name. The Life cycle is shown in ROS2 design document: https://design.ros2.org/articles/node_lifecycle.html We cannot use a LifecycleNode because it would expose change-state services to the rest of the ROS system. Only the Controller Manager should have possibility to change state of a controller.

Hopefully in the future we can use a LifecycleNode where we disable modifications from the outside.

◆ state_interface_configuration()
