Detailed Description

template<class ActionSpec>
class actionlib::ActionServerBase< ActionSpec >

The ActionServerBase implements the logic for an ActionServer.

Definition at line 62 of file action_server_base.h.

Member Typedef Documentation

template<class ActionSpec>

typedef ServerGoalHandle<ActionSpec> actionlib::ActionServerBase< ActionSpec >::GoalHandle

Reimplemented in actionlib::ActionServer< ActionSpec >, actionlib::ActionServer< TestAction >, and actionlib::RefServer.

Definition at line 65 of file action_server_base.h.

Constructor & Destructor Documentation

template<class ActionSpec >

actionlib::ActionServerBase< ActionSpec >::ActionServerBase	(	boost::function< void(GoalHandle)>	goal_cb,
		boost::function< void(GoalHandle)>	cancel_cb,
		bool	auto_start = `false`
	)

Constructor for an ActionServer.

Parameters:

goal_cb	A goal callback to be called when the ActionServer receives a new goal over the wire
cancel_cb	A cancel callback to be called when the ActionServer receives a new cancel request over the wire
auto_start	A boolean value that tells the ActionServer wheteher or not to start publishing as soon as it comes up. THIS SHOULD ALWAYS BE SET TO FALSE TO AVOID RACE CONDITIONS and start() should be called after construction of the server.
