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
