Returns the number of edges in this graph. If this graph is a directed graph, it counts the edge A to B as an edge, but B to A, if not present, isn't counted. A non-directed graph has an edge between A and B but also between B and A. This is counted as 1 edge, not two.

Gets or sets the edge producer func which produces edges for this graph. Used in some algorithms which have to produce edges.

Returns the edges in this graph.

if true, the graph is directed and only EdgeBase instances which have IsDirected set to true are allowed, otherwise it's a non-directed graph and EdgeBase instances which have IsDirected set to false are accepted.

Gets or sets a value indicating whether vertices which are not part of any edge anymore are removed from the graph when the edge they're part of is removed from the graph (so they effectively are orphaned). Default is false.

Gets or sets a value indicating whether events are blocked from being raised (true) or not (false, default)

Returns the number of vertices in this graph.
