Member Typedef Documentation

◆ CallbackType

template<typename ServiceT >

using rclcpp::Service< ServiceT >::CallbackType = std::function< void ( const std::shared_ptr<typename ServiceT::Request>, std::shared_ptr<typename ServiceT::Response>)>

◆ CallbackWithHeaderType

template<typename ServiceT >

Constructor & Destructor Documentation

◆ Service() [1/4]

template<typename ServiceT >

rclcpp::Service< ServiceT >::Service	(	std::shared_ptr< rcl_node_t >	node_handle,
		const std::string &	service_name,
		AnyServiceCallback< ServiceT >	any_callback,
		rcl_service_options_t &	service_options
	)

inline

Default constructor.

The constructor for a Service is almost never called directly. Instead, services should be instantiated through the function rclcpp::create_service().

Parameters

[in]	node_handle	NodeBaseInterface pointer that is used in part of the setup.
[in]	service_name	Name of the topic to publish to.
[in]	any_callback	User defined callback to call when a client request is received.
[in]	service_options	options for the subscription.

◆ Service() [2/4]

template<typename ServiceT >

rclcpp::Service< ServiceT >::Service	(	std::shared_ptr< rcl_node_t >	node_handle,
		std::shared_ptr< rcl_service_t >	service_handle,
		AnyServiceCallback< ServiceT >	any_callback
	)

inline

Default constructor.

The constructor for a Service is almost never called directly. Instead, services should be instantiated through the function rclcpp::create_service().

Parameters

[in]	node_handle	NodeBaseInterface pointer that is used in part of the setup.
[in]	service_handle	service handle.
[in]	any_callback	User defined callback to call when a client request is received.

◆ Service() [3/4]

template<typename ServiceT >

rclcpp::Service< ServiceT >::Service	(	std::shared_ptr< rcl_node_t >	node_handle,
		rcl_service_t *	service_handle,
		AnyServiceCallback< ServiceT >	any_callback
	)

inline

Default constructor.

The constructor for a Service is almost never called directly. Instead, services should be instantiated through the function rclcpp::create_service().

Parameters

[in]	node_handle	NodeBaseInterface pointer that is used in part of the setup.
[in]	service_handle	service handle.
[in]	any_callback	User defined callback to call when a client request is received.

Member Function Documentation

◆ take_request()

template<typename ServiceT >

bool rclcpp::Service< ServiceT >::take_request	(	typename ServiceT::Request &	request_out,
		rmw_request_id_t &	request_id_out
	)

inline

Take the next request from the service.

See also: ServiceBase::take_type_erased_request().

Parameters

[out]	request_out	The reference to a service request object into which the middleware will copy the taken request.
[out]	request_id_out	The output id for the request which can be used to associate response with this request in the future.

Returns: true if the request was taken, otherwise false.

Exceptions

rclcpp::exceptions::RCLError based exceptions if the underlying rcl calls fail.

◆ create_request()

template<typename ServiceT >

std::shared_ptr<void> rclcpp::Service< ServiceT >::create_request ( )

inlineoverridevirtual

Implements rclcpp::ServiceBase.

◆ create_request_header()

template<typename ServiceT >

std::shared_ptr<rmw_request_id_t> rclcpp::Service< ServiceT >::create_request_header ( )

inlineoverridevirtual

Implements rclcpp::ServiceBase.

◆ handle_request()

template<typename ServiceT >

void rclcpp::Service< ServiceT >::handle_request	(	std::shared_ptr< rmw_request_id_t >	request_header,
		std::shared_ptr< void >	request
	)

inlineoverridevirtual

Implements rclcpp::ServiceBase.

◆ send_response()

template<typename ServiceT >

void rclcpp::Service< ServiceT >::send_response	(	rmw_request_id_t &	req_id,
		typename ServiceT::Response &	response
	)
