NetTopologySuite.Planargraph.Subgraph Class Reference

A subgraph of a PlanarGraph. A subgraph may contain any subset of Edges from the parent graph. It will also automatically contain all DirectedEdges and Nodes associated with those edges. No new objects are created when edges are added - all associated components must already exist in the parent graph. More...

Detailed Description

A subgraph of a PlanarGraph. A subgraph may contain any subset of Edges from the parent graph. It will also automatically contain all DirectedEdges and Nodes associated with those edges. No new objects are created when edges are added - all associated components must already exist in the parent graph.
