#include <vtkMutableUndirectedGraph.h>
Detailed Description
An editable undirected graph.vtkMutableUndirectedGraph is an undirected graph with additional functions for adding vertices and edges. ShallowCopy(), DeepCopy(), CheckedShallowCopy(), and CheckedDeepCopy() will succeed when the argument is a vtkUndirectedGraph or vtkMutableUndirectedGraph.

Member Function Documentation
| static vtkMutableUndirectedGraph* vtkMutableUndirectedGraph::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkUndirectedGraph.
| virtual const char* vtkMutableUndirectedGraph::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkUndirectedGraph.
| static int vtkMutableUndirectedGraph::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type 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 vtkUndirectedGraph.
| virtual int vtkMutableUndirectedGraph::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 vtkUndirectedGraph.
| static vtkMutableUndirectedGraph* vtkMutableUndirectedGraph::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkUndirectedGraph.
| void vtkMutableUndirectedGraph::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [virtual] |
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 vtkUndirectedGraph.
Allocates space for the specified number of vertices in the graph's internal data structures. The previous number of vertices is returned on success and -1 is returned on failure. 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, no allocation will be performed, and a value of -1 will be returned.
| vtkIdType vtkMutableUndirectedGraph::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 vtkMutableUndirectedGraph::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 vtkMutableUndirectedGraph::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.

| vtkGraphEdge* vtkMutableUndirectedGraph::AddGraphEdge | ( | vtkIdType | u, | |

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().

- This is a less efficient method for use with wrappers. In C++ you should use the faster AddEdge().
