Member Function Documentation

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
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
dethe directed edge to test.
opCodethe overlap operation
edgesthe list of included line edges.
