Detailed Description

Adaptor for reversing all arcs of an underlying graph.

Node and Arc objects are interchangeable between the adaptor and the original graph. The underlying graph can be freely modified while using this adaptor.

int Satsuma.ReverseGraph.ArcCount	(	Node	u,
		ArcFilter	filter = `ArcFilter.All`
	)

Returns the number of arcs adjacent to a specific node satisfying a given filter.

Parameters

int Satsuma.ReverseGraph.ArcCount	(	Node	u,
		Node	v,
		ArcFilter	filter = `ArcFilter.All`
	)

Returns the number of arcs adjacent to two nodes satisfying a given filter.

Parameters

Implements Satsuma.IGraph.

IEnumerable<Arc> Satsuma.ReverseGraph.Arcs ( ArcFilter filter = ArcFilter.All )

Returns all arcs of the graph satisfying a given filter.

Parameters

filter

Cannot be ArcType.Forward/ArcType.Backward.

If ArcFilter.All, then all arcs are returned.
If ArcFilter.Edge, only the edges (undirected arcs) are returned.

Implements Satsuma.IGraph.

Definition at line 71 of file ReverseGraph.cs.

IEnumerable<Arc> Satsuma.ReverseGraph.Arcs	(	Node	u,
		ArcFilter	filter = `ArcFilter.All`
	)

Returns all arcs adjacent to a specific node satisfying a given filter.

Parameters

filter

If ArcFilter.All, then all arcs are returned.
If ArcFilter.Edge, only the edges (undirected arcs) are returned.
If ArcFilter.Forward, only the arcs exiting u (this includes edges) are returned.
If ArcFilter.Backward, only the arcs entering u (this includes edges) are returned.

IEnumerable<Arc> Satsuma.ReverseGraph.Arcs	(	Node	u,
		Node	v,
		ArcFilter	filter = `ArcFilter.All`
	)

Returns all arcs adjacent to two nodes satisfying a given filter.

Parameters

filter

If ArcFilter.All, then all arcs are returned.
If ArcFilter.Edge, only the edges (undirected arcs) are returned.
If ArcFilter.Forward, only the arcs from u to v (this includes edges) are returned.
If ArcFilter.Backward, only the arcs from v to u (this includes edges) are returned.

bool Satsuma.ReverseGraph.HasArc ( Arc arc )

Returns whether the given arc is contained in the graph.

Must return the same value as Arcs().Contains in all implementations, but faster if possible.

Note: true may be returned for arcs coming from another graph as well, if those arcs encapsulate an identifier which is valid for this graph, too.

bool Satsuma.ReverseGraph.HasNode ( Node node )

Returns whether the given node is contained in the graph.

Must return the same value as Nodes().Contains in all implementations, but faster if possible.

Note: true may be returned for nodes coming from another graph as well, if those nodes encapsulate an identifier which is valid for this graph, too.

Implements Satsuma.IGraph.

bool Satsuma.ReverseGraph.IsEdge ( Arc arc )

Returns whether the arc is undirected (true) or directed (false).

Implements Satsuma.IArcLookup.

Definition at line 61 of file ReverseGraph.cs.

int Satsuma.ReverseGraph.NodeCount ( )

Returns the total number of nodes in O(1) time.

Implements Satsuma.IGraph.

Definition at line 86 of file ReverseGraph.cs.

IEnumerable<Node> Satsuma.ReverseGraph.Nodes ( )

Returns all nodes of the graph.
