Member Function Documentation

build()

std::vector< geom::LineString * > * geos::operation::overlay::LineBuilder::build

(

OverlayOp::OpCode

opCode

)

Returns

a list of the LineStrings in the result of the specified overlay operation

collectLineEdge()

void geos::operation::overlay::LineBuilder::collectLineEdge	(	geomgraph::DirectedEdge *	de,
		OverlayOp::OpCode	opCode,
		std::vector< geomgraph::Edge * > *	edges
	)

Collect line edges which are in the result.

Line edges are in the result if they are not part of an area boundary, if they are in the result of the overlay operation, and if they are not covered by a result area.

Parameters

de	the directed edge to test.
opCode	the overlap operation
edges	the list of included line edges.
