bool geos::noding::snapround::MCIndexPointSnapper::snap (  HotPixel &  hotPixel, SegmentString *  parentEdge, unsigned int  vertexIndex )

Snaps (nodes) all interacting segments to this hot pixel. The hot pixel may represent a vertex of an edge, in which case this routine uses the optimization of not noding the vertex itself Parameters: hotPixel  the hot pixel to snap to parentEdge  the edge containing the vertex, if applicable, or null vertexIndex  the index of the vertex, if applicable, or -1 Returns: true if a node was added for this pixel
