All Implemented Interfaces:

java.io.Serializable

class HandMovementInTransition

extends HandMovement

This does a transition of between a half and one bar.

Over first half a bar, we retract from the first position. Over the last half a bar, we extend out to the second postion. Note that these two processes will overlap if the transition period is less than a bar.

If the transition period is more than half a bar and less than a bar then the hand transition will take place in three linear movements. The hand will start by withdrawing to the shoulder position, then it will move away from the old position and towards the new position, then it will extend to the new position.

Note also that if the new and the old position happen to be the same and we have only half a bar to transition then the hand will be held in the same position throughout the transition. This will happen if the same hands are held in the same way in two consecutive units or hand holds. Although there will be a half bar transition created, it will not be seen and the hands will remain in place and together throughout.
