Detailed Description

Recompute the transition relative to each element of the path vector

When executing a sequence of direct paths on a real robot, it is useful to know which transition of the graph each direct path corresponds to. For example, in a manipulation motion, before grasping an object, the robot needs to open the gripper. This information is contained in the transition that leads to a pregrasp waypoint state. The direct path should therefore have access to the transition.

The information is stored in the constraint set of the path and is accessible via method edge .

If the path vector is produced by a manipulation planner, each direct path has been created by a transition. However, the path may later be cut by random shortcut or due to collision and the associated transition become irrelevant. For example if a path is created by a transition that leads to a pre-grasp, and cut due to a collision, the path does not reach the target state and the relevant transition is not the one that built the path.

This class takes a path vector as input an relabel each direct path with the correct transition.

Precondition: The path should have been created by a manipulation planning algorithm: in other words, the constraint set of each direct path should be of type hpp::manipulation::ConstraintSet.
