| boost::shared_ptr< const Goal > | acceptNewGoal () |
| Accepts a new goal when one is available. The status of this goal is set to active upon acceptance, and the status of any previously active goal is set to preempted. Preempts received for the new goal between checking if isNewGoalAvailable or invocation of a goal callback and the acceptNewGoal call will not trigger a preempt callback. This means, isPreemptRequested should be called after accepting the goal even for callback-based implementations to make sure the new goal does not have a pending preempt request. More... | |

SimpleActionServer implements a single goal policy on top of the ActionServer class. The specification of the policy is as follows: only one goal can have an active status at a time, new goals preempt previous goals based on the stamp in their GoalID field (later goals preempt earlier ones), an explicit preempt goal preempts all goals with timestamps that are less than or equal to the stamp associated with the preempt, accepting a new goal implies successful preemption of any old goal and the status of the old goal will be changed automatically to reflect this.
