Client side handle to monitor goal progress.
A ClientGoalHandle is a reference counted object that is used to manipulate and monitor the progress of an already dispatched goal. Once all the goal handles go out of scope (or are reset), an ActionClient stops maintaining state for that goal.

Create an empty goal handle.
Constructs a goal handle that doesn't track any goal. Calling any method on an empty goal handle other than operator= will trigger an assertion.

| void actionlib::ClientGoalHandle< ActionSpec >::cancel | ( | ) |
Sends a cancel message for this specific goal to the ActionServer.
Also transitions the Communication State Machine to WAITING_FOR_CANCEL_ACK
Definition at line 205 of file client_goal_handle_imp.h.
| CommState actionlib::ClientGoalHandle< ActionSpec >::getCommState | ( | ) |
Get the state of this goal's communication state machine from interaction with the server.
Possible States are: WAITING_FOR_GOAL_ACK, PENDING, ACTIVE, WAITING_FOR_RESULT, WAITING_FOR_CANCEL_ACK, RECALLING, PREEMPTING, DONE
Definition at line 92 of file client_goal_handle_imp.h.
| ClientGoalHandle< ActionSpec >::ResultConstPtr actionlib::ClientGoalHandle< ActionSpec >::getResult | ( | ) |
Get result associated with this goal.
Definition at line 161 of file client_goal_handle_imp.h.
| TerminalState actionlib::ClientGoalHandle< ActionSpec >::getTerminalState | ( | ) |
Get the terminal state information for this goal.
Possible States Are: RECALLED, REJECTED, PREEMPTED, ABORTED, SUCCEEDED, LOST This call only makes sense if CommState==DONE. This will send ROS_WARNs if we're not in DONE
Definition at line 114 of file client_goal_handle_imp.h.
| bool actionlib::ClientGoalHandle< ActionSpec >::isExpired | ( | ) | const [inline] |
Checks if this goal handle is tracking a goal.
Has pretty much the same semantics as boost::shared_ptr::expired()
Definition at line 85 of file client_goal_handle_imp.h.
| bool actionlib::ClientGoalHandle< ActionSpec >::operator!= | ( | const ClientGoalHandle< ActionSpec > & | rhs | ) |
!(operator==())
Definition at line 275 of file client_goal_handle_imp.h.
| bool actionlib::ClientGoalHandle< ActionSpec >::operator== | ( | const ClientGoalHandle< ActionSpec > & | rhs | ) |
Check if two goal handles point to the same goal.
Definition at line 254 of file client_goal_handle_imp.h.
| void actionlib::ClientGoalHandle< ActionSpec >::resend | ( | ) |
Resends this goal [with the same GoalID] to the ActionServer.
Useful if the user thinks that the goal may have gotten lost in transit
Definition at line 179 of file client_goal_handle_imp.h.
| void actionlib::ClientGoalHandle< ActionSpec >::reset | ( | ) |
Stops goal handle from tracking a goal.
Useful if you want to stop tracking the progress of a goal, but it is inconvenient to force the goal handle to go out of scope. Has pretty much the same semantics as boost::shared_ptr::reset()
