Detailed Description

Copies of graphs with mapping between nodes and edges.

The class GraphCopySimple represents a copy of a graph and maintains a mapping between the nodes and edges of the original graph to the copy and vice versa.

New nodes and edges can be added to the copy; the counterpart of those nodes and edges is 0 indicating that there is no counterpart. This class does not support splitting of edges in such a way that both edges resulting from the split are mapped to the same original edge; this feature is provided by GraphCopy.

overridevirtual

Removes edge e.

Callback notifying subclasses that insert() copied an edge.

Parameters

originalthe original edge
copythe created copy

Reimplemented from ogdf::Graph.

◆ newEdge() [1/6]

edge ogdf::Graph::newEdge
inline

Creates a new edge at predefined positions in the adjacency lists.

Let v be the node whose adjacency list contains adjSrc, and w the node whose adjacency list contains adjTgt. Then, the created edge is (v,w).

Parameters
adjSrcis the adjacency entry before / after which the new edge is inserted in the adjacency list of v.
adjTgtis the adjacency entry before / after which the new edge is inserted in the adjacency list of w.
dirspecifies if the edge is inserted before or after the given adjacency entries.
indexis the index that will be assigned to the newly created edge. If negative or not given will use the next free index maxEdgeIndex(). Passing an edge index that is already in use results in an inconsistent data structure. Only specify this parameter if you know what you're doing!
Returns
the newly created edge.

Definition at line 1135 of file Graph_d.h.

◆ newEdge() [2/6]

edge ogdf::Graph::newEdge
inline

Creates a new edge at predefined positions in the adjacency lists.

Let v be the node whose adjacency list contains adjSrc. Then, the created edge is (v,w).

Parameters
adjSrcis the adjacency entry after which the new edge is inserted in the adjacency list of v.
wis the target node of the new edge; the edge is added at the end of the adjacency list of w.
indexis the index that will be assigned to the newly created edge. If negative or not given will use the next free index maxEdgeIndex(). Passing an edge index that is already in use results in an inconsistent data structure. Only specify this parameter if you know what you're doing!

Definition at line 1113 of file Graph_d.h.

◆ newEdge() [3/6]

edge ogdf::GraphCopySimple::newEdge ( edge  eOrig)
inline

Creates a new edge in the graph copy with original edge eOrig.

Warning
You have to make sure that the original edge makes sense, in particular that eOrig is not the original edge of another edge in the copy.

Definition at line 314 of file GraphCopy.h.

◆ newEdge() [4/6]

edge ogdf::Graph::newEdge
inline

Creates a new edge at predefined positions in the adjacency lists.

Let w be the node whose adjacency list contains adjTgt. Then, the created edge is (v,w).

Parameters
vis the source node of the new edge; the edge is added at the end of the adjacency list of v.
adjTgtis the adjacency entry after which the new edge is inserted in the adjacency list of w.
indexis the index that will be assigned to the newly created edge. If negative or not given will use the next free index maxEdgeIndex(). Passing an edge index that is already in use results in an inconsistent data structure. Only specify this parameter if you know what you're doing!
Returns
the newly created edge.

Definition at line 1094 of file Graph_d.h.

◆ newEdge() [5/6]
