For alternating posession, it is when the throw in ends. So in this case. If A was inbounding the ball because of an alternating posession and commited a violatin, B gets the ball, but the arrow still points to A. The violation includes throwing the ball out of bounds without touching someone.

This is different for the start of a game which is not alternating posession. For example, if during the initial jump ball, team B commits a violation, team will get the ball and the arrow is set to team B when the ball is at the throwers disposal. If then, A commits a throw in violation, B gets the ball, but still will have the arrow.
