◆ create_client() [1/2]

template<typename ActionT >

Client<ActionT>::SharedPtr rclcpp_action::create_client	(	rclcpp::node_interfaces::NodeBaseInterface::SharedPtr	node_base_interface,
		rclcpp::node_interfaces::NodeGraphInterface::SharedPtr	node_graph_interface,
		rclcpp::node_interfaces::NodeLoggingInterface::SharedPtr	node_logging_interface,
		rclcpp::node_interfaces::NodeWaitablesInterface::SharedPtr	node_waitables_interface,
		const std::string &	name,
		rclcpp::CallbackGroup::SharedPtr	group = `nullptr`
	)

Create an action client.

This function is equivalent to

See also: create_client()` however is using the individual node interfaces to create the client.

Parameters

[in]	node_base_interface	The node base interface of the corresponding node.
[in]	node_graph_interface	The node graph interface of the corresponding node.
[in]	node_logging_interface	The node logging interface of the corresponding node.
[in]	node_waitables_interface	The node waitables interface of the corresponding node.
[in]	name	The action name.
[in]	group	The action client will be added to this callback group. If `nullptr`, then the action client is added to the default callback group.

◆ create_client() [2/2]

template<typename ActionT , typename NodeT >

Client<ActionT>::SharedPtr rclcpp_action::create_client	(	NodeT	node,
		const std::string &	name,
		rclcpp::CallbackGroup::SharedPtr	group = `nullptr`
	)

Create an action client.

Parameters

[in]	node	The action client will be added to this node.
[in]	name	The action name.
[in]	group	The action client will be added to this callback group. If `nullptr`, then the action client is added to the default callback group.

◆ create_server() [1/2]

template<typename ActionT >

Server<ActionT>::SharedPtr rclcpp_action::create_server	(	rclcpp::node_interfaces::NodeBaseInterface::SharedPtr	node_base_interface,
		rclcpp::node_interfaces::NodeClockInterface::SharedPtr	node_clock_interface,
		rclcpp::node_interfaces::NodeLoggingInterface::SharedPtr	node_logging_interface,
		rclcpp::node_interfaces::NodeWaitablesInterface::SharedPtr	node_waitables_interface,
		const std::string &	name,
		typename Server< ActionT >::GoalCallback	handle_goal,
		typename Server< ActionT >::CancelCallback	handle_cancel,
		typename Server< ActionT >::AcceptedCallback	handle_accepted,
		const rcl_action_server_options_t &	options = `rcl_action_server_get_default_options()`,
		rclcpp::CallbackGroup::SharedPtr	group = `nullptr`
	)

Create an action server.

All provided callback functions must be non-blocking. This function is equivalent to

See also: create_server()` however is using the individual node interfaces to create the server.; Server::Server() for more information.

Parameters

[in]	node_base_interface	The node base interface of the corresponding node.
[in]	node_clock_interface	The node clock interface of the corresponding node.
[in]	node_logging_interface	The node logging interface of the corresponding node.
[in]	node_waitables_interface	The node waitables interface of the corresponding node.
[in]	name	The action name.
[in]	handle_goal	A callback that decides if a goal should be accepted or rejected.
[in]	handle_cancel	A callback that decides if a goal should be attempted to be canceled. The return from this callback only indicates if the server will try to cancel a goal. It does not indicate if the goal was actually canceled.
[in]	handle_accepted	A callback that is called to give the user a handle to the goal.
[in]	options	options to pass to the underlying `rcl_action_server_t`.
[in]	group	The action server will be added to this callback group. If `nullptr`, then the action server is added to the default callback group.

◆ create_server() [2/2]

template<typename ActionT , typename NodeT >

Server<ActionT>::SharedPtr rclcpp_action::create_server	(	NodeT	node,
		const std::string &	name,
		typename Server< ActionT >::GoalCallback	handle_goal,
		typename Server< ActionT >::CancelCallback	handle_cancel,
		typename Server< ActionT >::AcceptedCallback	handle_accepted,
		const rcl_action_server_options_t &	options = `rcl_action_server_get_default_options()`,
		rclcpp::CallbackGroup::SharedPtr	group = `nullptr`
	)

Create an action server.

All provided callback functions must be non-blocking.

See also: Server::Server() for more information.

Parameters

[in]	node]	The action server will be added to this node.
[in]	name	The action name.
[in]	handle_goal	A callback that decides if a goal should be accepted or rejected.
[in]	handle_cancel	A callback that decides if a goal should be attempted to be canceled. The return from this callback only indicates if the server will try to cancel a goal. It does not indicate if the goal was actually canceled.
[in]	handle_accepted	A callback that is called to give the user a handle to the goal.
[in]	options	options to pass to the underlying `rcl_action_server_t`.
[in]	group	The action server will be added to this callback group. If `nullptr`, then the action server is added to the default callback group.

◆ to_string()

RCLCPP_ACTION_PUBLIC std::string rclcpp_action::to_string ( const GoalUUID & goal_id )

Convert a goal id to a human readable string.

◆ convert() [1/2]

RCLCPP_ACTION_PUBLIC void rclcpp_action::convert	(	const GoalUUID &	goal_id,
		rcl_action_goal_info_t *	info
	)

◆ convert() [2/2]
