Detailed Description

An editable directed graph.

vtkMutableDirectedGraph is a directed graph which has additional methods for adding edges and vertices. AddChild() is a convenience method for constructing trees. ShallowCopy(), DeepCopy(), CheckedShallowCopy() and CheckedDeepCopy() will succeed for instances of vtkDirectedGraph, vtkMutableDirectedGraph and vtkTree.

virtual vtkIdType vtkMutableDirectedGraph::SetNumberOfVertices ( vtkIdType  numVerts)
virtual

Allocates space for the specified number of vertices in the graph's internal data structures. This has no effect on the number of vertex coordinate tuples or vertex attribute tuples allocated; you are responsible for guaranteeing these match. Also, this call is not implemented for distributed-memory graphs since the semantics are unclear; calling this function on a graph with a non-NULL DistributedGraphHelper will generate an error message and no allocation will be performed.

vtkIdType vtkMutableDirectedGraph::AddVertex ( )

Adds a vertex to the graph and returns the index of the new vertex.

Note
In a distributed graph (i.e. a graph whose DistributedHelper is non-null), this routine cannot be used to add a vertex if the vertices in the graph have pedigree IDs, because this routine will always add the vertex locally, which may conflict with the proper location of the vertex based on the distribution of the pedigree IDs.
vtkIdType vtkMutableDirectedGraph::AddVertex ( vtkVariantArray *  propertyArr)

Adds a vertex to the graph with associated properties defined in propertyArr and returns the index of the new vertex. The number and order of values in propertyArr must match up with the arrays in the vertex data retrieved by GetVertexData(). If a vertex with the given pedigree ID already exists, its properties will be overwritten with the properties in propertyArr and the existing vertex index will be returned.

Note
In a distributed graph (i.e. a graph whose DistributedHelper is non-null) the vertex added or found might not be local. In this case, AddVertex will wait until the vertex can be added or found remotely, so that the proper vertex index can be returned. If you don't actually need to use the vertex index, consider calling LazyAddVertex, which provides better performance by eliminating the delays associated with returning the vertex index.
vtkIdType vtkMutableDirectedGraph::AddVertex ( const vtkVariant &  pedigreeId)

Adds a vertex with the given pedigreeID to the graph and returns the index of the new vertex. If a vertex with the given pedigree ID already exists, the existing vertex index will be returned.

Note
In a distributed graph (i.e. a graph whose DistributedHelper is non-null) the vertex added or found might not be local. In this case, AddVertex will wait until the vertex can be added or found remotely, so that the proper vertex index can be returned. If you don't actually need to use the vertex index, consider calling LazyAddVertex, which provides better performance by eliminating the delays associated with returning the vertex index.
vtkEdgeType vtkMutableDirectedGraph::AddEdge ( vtkIdType  u,
vtkIdType  v 
)

Adds a directed edge from u to v, where u and v are vertex indices, and returns a vtkEdgeType structure describing that edge. vtkEdgeType contains fields for Source vertex index, Target vertex index, and edge index Id.

vtkEdgeType vtkMutableDirectedGraph::AddEdge ( vtkIdType  u,
vtkIdType  v,
vtkVariantArray *  propertyArr 
)

Adds a directed edge from u to v, where u and v are vertex indices, with associated properties defined in propertyArr and returns a vtkEdgeType structure describing that edge. The number and order of values in propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). vtkEdgeType contains fields for Source vertex index, Target vertex index, and edge index Id.

vtkEdgeType vtkMutableDirectedGraph::AddEdge ( const vtkVariant &  u,
vtkIdType  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u is a vertex pedigree ID and v is a vertex index, and returns a vtkEdgeType structure describing that edge. The number and order of values in the optional parameter propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). vtkEdgeType contains fields for Source vertex index, Target vertex index, and edge index Id.

vtkEdgeType vtkMutableDirectedGraph::AddEdge ( vtkIdType  u,
const vtkVariant &  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u is a vertex index and v is a vertex pedigree ID, and returns a vtkEdgeType structure describing that edge. The number and order of values in the optional parameter propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). vtkEdgeType contains fields for Source vertex index, Target vertex index, and edge index Id.

vtkEdgeType vtkMutableDirectedGraph::AddEdge ( const vtkVariant &  u,
const vtkVariant &  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u and v are vertex pedigree IDs, and returns a vtkEdgeType structure describing that edge. The number and order of values in the optional parameter propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). vtkEdgeType contains fields for Source vertex index, Target vertex index, and edge index Id.

void vtkMutableDirectedGraph::LazyAddVertex ( )

Adds a vertex to the graph. This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

void vtkMutableDirectedGraph::LazyAddVertex ( vtkVariantArray *  propertyArr)

Adds a vertex to the graph with associated properties defined in propertyArr. The number and order of values in propertyArr must match up with the arrays in the vertex data retrieved by GetVertexData(). If a vertex with the given pedigree ID already exists, its properties will be overwritten with the properties in propertyArr. This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

void vtkMutableDirectedGraph::LazyAddVertex ( const vtkVariant &  pedigreeId)

Adds a vertex with the given pedigreeID to the graph. If a vertex with the given pedigree ID already exists, no operation is performed. This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

void vtkMutableDirectedGraph::LazyAddEdge ( vtkIdType  u,
vtkIdType  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u and v are vertex indices.

This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

void vtkMutableDirectedGraph::LazyAddEdge ( const vtkVariant &  u,
vtkIdType  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u is a vertex pedigree ID and v is a vertex index. The number and order of values in the optional parameter propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

void vtkMutableDirectedGraph::LazyAddEdge ( vtkIdType  u,
const vtkVariant &  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u is a vertex index and v is a vertex pedigree ID. The number and order of values in the optional parameter propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

void vtkMutableDirectedGraph::LazyAddEdge ( const vtkVariant &  u,
const vtkVariant &  v,
vtkVariantArray *  propertyArr = 0 
)

Adds a directed edge from u to v, where u and v are vertex pedigree IDs. The number and order of values in the optional parameter propertyArr must match up with the arrays in the edge data retrieved by GetEdgeData(). This method is lazily evaluated for distributed graphs (i.e. graphs whose DistributedHelper is non-null) the next time Synchronize is called on the helper.

vtkGraphEdge* vtkMutableDirectedGraph::AddGraphEdge ( vtkIdType  u,
vtkIdType  v 
)

Variant of AddEdge() that returns a heavyweight vtkGraphEdge object. The graph owns the reference of the edge and will replace its contents on the next call to AddGraphEdge().

Note
This is a less efficient method for use with wrappers. In C++ you should use the faster AddEdge().
vtkIdType vtkMutableDirectedGraph::AddChild ( vtkIdType  parent,
vtkVariantArray *  propertyArr 
)

Convenience method for creating trees. Returns the newly created vertex id. Shortcut for

vtkIdType v = g->AddVertex();
g->AddEdge(parent, v);

If non-null, propertyArr provides edge properties for the newly-created edge. The values in propertyArr must match up with the arrays in the edge data returned by GetEdgeData().

vtkIdType vtkMutableDirectedGraph::AddChild ( vtkIdType  parent)
inline

Convenience method for creating trees. Returns the newly created vertex id. Shortcut for

vtkIdType v = g->AddVertex();
g->AddEdge(parent, v);

If non-null, propertyArr provides edge properties for the newly-created edge. The values in propertyArr must match up with the arrays in the edge data returned by GetEdgeData().
