question: private void computeSnaps ( Collection segStrings , Collection snapPts ) { for ( Iterator i0 = segStrings . iterator ( ) ; i0 . hasNext ( ) ; ) { NodedSegmentString ss = ( NodedSegmentString ) i0 . next ( ) ; computeSnaps ( ss , snapPts ) ; } }
target:  Computes nodes introduced as a result of snapping segments to snap points (hot pixels)
