◆ add() [1/2]

void geos::operation::buffer::PolygonBuilder::add ( const std::vector< geomgraph::DirectedEdge * > * dirEdges,
const std::vector< geomgraph::Node * > * nodes )

Add a set of edges and nodes, which form a graph. The graph is assumed to contain one or more polygons, possibly with holes.

◆ add() [2/2]

void geos::operation::buffer::PolygonBuilder::add ( geomgraph::PlanarGraph * graph)

Add a complete graph. The graph is assumed to contain one or more polygons, possibly with holes.
