Detailed Description

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

Member Function Documentation

snap()

bool geos::noding::snapround::MCIndexPointSnapper::snap	(	HotPixel &	hotPixel,
		SegmentString *	parentEdge,
		std::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

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
