Detailed Description

An undirected graph.

vtkUndirectedGraph is a collection of vertices along with a collection of undirected edges (they connect two vertices in no particular order). ShallowCopy(), DeepCopy(), CheckedShallowCopy(), CheckedDeepCopy() accept instances of vtkUndirectedGraph and vtkMutableUndirectedGraph. GetOutEdges(v, it) and GetInEdges(v, it) return the same list of edges, which is the list of all edges which have a v as an endpoint. GetInDegree(v), GetOutDegree(v) and GetDegree(v) all return the full degree of vertex v.

vtkUndirectedGraph is read-only. To create an undirected graph, use an instance of vtkMutableUndirectedGraph, then you may set the structure to a vtkUndirectedGraph using ShallowCopy().

◆ IsTypeOf()

static vtkTypeBool vtkUndirectedGraph::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkUndirectedGraph::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGraph.

Reimplemented in vtkMolecule, and vtkMutableUndirectedGraph.

◆ NewInstance()

◆ PrintSelf()

void vtkUndirectedGraph::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkGraph.

◆ GetDataObjectType()

int vtkUndirectedGraph::GetDataObjectType ( )

inlineoverridevirtual

Return what type of dataset this is.

Reimplemented from vtkGraph.

Definition at line 97 of file vtkUndirectedGraph.h.

◆ GetInDegree()

vtkIdType vtkUndirectedGraph::GetInDegree ( vtkIdType v )

overridevirtual

Returns the full degree of the vertex.

Reimplemented from vtkGraph.

◆ GetInEdge() [1/2]

vtkInEdgeType vtkUndirectedGraph::GetInEdge	(	vtkIdType	v,
		vtkIdType	i
	)

overridevirtual

Random-access method for retrieving the in edges of a vertex.

For an undirected graph, this is the same as the out edges.

Reimplemented from vtkGraph.

◆ GetInEdge() [2/2]

void vtkUndirectedGraph::GetInEdge	(	vtkIdType	v,
		vtkIdType	i,
		vtkGraphEdge *	e
	)

inlineoverridevirtual

Random-access method for retrieving incoming edges to vertex v.

The method fills the vtkGraphEdge instance with the id, source, and target of the edge. This method is provided for wrappers, GetInEdge(vtkIdType, vtkIdType) is preferred.

Reimplemented from vtkGraph.

Definition at line 116 of file vtkUndirectedGraph.h.

◆ GetData() [1/2]

static vtkUndirectedGraph * vtkUndirectedGraph::GetData ( vtkInformation * info )

static

Retrieve a graph from an information vector.

◆ GetData() [2/2]

static vtkUndirectedGraph * vtkUndirectedGraph::GetData	(	vtkInformationVector *	v,
		int	i = `0`
	)

static

Retrieve a graph from an information vector.

◆ GetInEdges() [1/2]

void vtkUndirectedGraph::GetInEdges	(	vtkIdType	v,
		vtkInEdgeIterator *	it
	)

inlineoverridevirtual

Initialize the iterator to get the incoming edges to a vertex.

For an undirected graph, this is all incident edges.

Reimplemented from vtkGraph.

Definition at line 133 of file vtkUndirectedGraph.h.

◆ IsStructureValid()

bool vtkUndirectedGraph::IsStructureValid ( vtkGraph * g )

overridevirtual

Check the structure, and accept it if it is a valid undirected graph.

This is public to allow the ToDirected/UndirectedGraph to work.

Implements vtkGraph.

◆ GetInEdges() [2/2]

void vtkUndirectedGraph::GetInEdges	(	vtkIdType	v,
		const vtkInEdgeType *&	edges,
		vtkIdType &	nedges
	)

overrideprotectedvirtual

For iterators, returns the same edge list as GetOutEdges().
