setEdgeDepths method
Set both edge depths. One depth for a given side is provided. The other is computed depending on the Location transition and the depthDelta of the edge.
Implementation
void setEdgeDepths(int position, int depth) {
// get the depth transition delta from R to L for this directed Edge
int depthDelta = getEdge().getDepthDelta();
if (!_isForward) depthDelta = -depthDelta;
// if moving from L to R instead of R to L must change sign of delta
int directionFactor = 1;
if (position == Position.LEFT) directionFactor = -1;
int oppositePos = Position.opposite(position);
int delta = depthDelta * directionFactor;
//TESTINGint delta = depthDelta * DirectedEdge.depthFactor(loc, oppositeLoc);
int oppositeDepth = depth + delta;
setDepth(position, depth);
setDepth(oppositePos, oppositeDepth);
}
