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.

See also

Server::Server() for more information.

Parameters:

  • node_base_interface – [in] The node base interface of the corresponding node.

  • node_clock_interface – [in] The node clock interface of the corresponding node.

  • node_logging_interface – [in] The node logging interface of the corresponding node.

  • node_waitables_interface – [in] The node waitables interface of the corresponding node.

  • name – [in] The action name.

  • handle_goal – [in] A callback that decides if a goal should be accepted or rejected.

  • handle_cancel – [in] 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.

  • handle_accepted – [in] A callback that is called to give the user a handle to the goal.

  • options – [in] Options to pass to the underlying rcl_action_server_t.

  • group – [in] The action server will be added to this callback group. If nullptr, then the action server is added to the default callback group.
