Constructor Detail

### MCIndexPointSnapper

    public MCIndexPointSnapper(java.util.Collection monoChains,
                               SpatialIndex index)

Method Detail

### snap

    public boolean snap(HotPixel hotPixel,
                        SegmentString parentEdge,
                        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

### snap

    public boolean snap(HotPixel hotPixel)
