Traits for graph data structures.
The traits for graph data structures provide an additional level of information about (the edges of) the graph. There are three levels:
Graph
: an undirected graph, edges have no defined source or sink.Digraph
: a directed graph, each edge has a designated source and a designated sink node. Furthermore, there is the concept of "outgoing" and "incoming" edges. ADigraph
is also aGraph
, which basically means ignoring the direction information of the edges.Network
: a network is a directed graph, but each edge is actually a pair of edges: the normally directed edge and its reverse edge. Edge and reverse edge are considered equal for all purposes of a digraph (e.g. source and sink node are always source and sink of the forward edge), but the additional "reverse" information can be obtained by the methods ofNetwork
. Furthermore, if the network is anIndexNetwork
, aBiEdgeVec
can be used to store different values for edges and the reverse edges (in contrast, anEdgeVec
always contains the same value for an edge and its reverse edge).
