add
public void add(Collection dirEdges,
Collection 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
public void add(PlanarGraph graph)
Add a complete graph.
The graph is assumed to contain one or more polygons,
possibly with holes.
containsPoint
public boolean containsPoint(Coordinate p)
Checks the current set of shells (with their associated holes) to
see if any of them contain the point.
getPolygons
public List getPolygons()
