Detailed Description

"Snaps" all SegmentStrings in a SpatialIndex containing MonotoneChains to a given HotPixel.

Member Function Documentation

bool geos::noding::snapround::MCIndexPointSnapper::snap ( HotPixel hotPixel,
SegmentString parentEdge,
size_t  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
hotPixelthe hot pixel to snap to
parentEdgethe edge containing the vertex, if applicable, or null
vertexIndexthe index of the vertex, if applicable, or -1
Returns
true if a node was added for this pixel
