question: public void add ( long start , long end , SequenceNameLocus region ) { if ( mSize == mStarts . length ) { final int newLen = mStarts . length * 3 / 2 + 1 ; mStarts = Arrays . copyOf ( mStarts , newLen ) ; mEnds = Arrays . copyOf ( mEnds , newLen ) ; mRegions = Arrays . copyOf ( mRegions , newLen ) ; } mStarts [ mSize ] = start ; mEnds [ mSize ] = end ; mRegions [ mSize ] = region ; mSize ++ ; }
target:  Adds a new start, end pair.
