Detailed Description

A rooted tree data structure.

vtkTree is a connected directed graph with no cycles. A tree is a type of directed graph, so works with all graph algorithms.

vtkTree is a read-only data structure. To construct a tree, create an instance of vtkMutableDirectedGraph. Add vertices and edges with AddVertex() and AddEdge(). You may alternately start by adding a single vertex as the root then call graph->AddChild(parent) which adds a new vertex and connects the parent to the child. The tree MUST have all edges in the proper direction, from parent to child. After building the tree, call tree->CheckedShallowCopy(graph) to copy the structure into a vtkTree. This method will return false if the graph is an invalid tree.

vtkTree provides some convenience methods for obtaining the parent and children of a vertex, for finding the root, and determining if a vertex is a leaf (a vertex with no children).

Member Function Documentation

static vtkTree* vtkTree::New ( )

static

virtual const char* vtkTree::GetClassName ( )

virtual

Reimplemented from vtkDirectedAcyclicGraph.

static int vtkTree::IsTypeOf ( const char *  type )

static

virtual int vtkTree::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 vtkDirectedAcyclicGraph.

static vtkTree* vtkTree::SafeDownCast ( vtkObject *  o )

static

void vtkTree::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 vtkDirectedAcyclicGraph.

virtual int vtkTree::GetDataObjectType ( )

inlinevirtual

Return what type of dataset this is.

Reimplemented from vtkDirectedAcyclicGraph.

Definition at line 66 of file vtkTree.h.

virtual vtkIdType vtkTree::GetRoot ( )

virtual

Get the root vertex of the tree.

vtkIdType vtkTree::GetNumberOfChildren ( vtkIdType  v )

inline

Get the number of children of a vertex.

Definition at line 75 of file vtkTree.h.

vtkIdType vtkTree::GetChild	(	vtkIdType	v,
		vtkIdType	i
	)

Get the i-th child of a parent vertex.

void vtkTree::GetChildren ( vtkIdType  v, vtkAdjacentVertexIterator *  it  )

inline

Get the child vertices of a vertex. This is a convenience method that functions exactly like GetAdjacentVertices.

Definition at line 85 of file vtkTree.h.

vtkIdType vtkTree::GetParent

(

vtkIdType

v

)

Get the parent of a vertex.

vtkEdgeType vtkTree::GetParentEdge

(

vtkIdType

v

)

Get the edge connecting the vertex to its parent.

vtkIdType vtkTree::GetLevel

(

vtkIdType

v

)

Get the level of the vertex in the tree. The root vertex has level 0. Returns -1 if the vertex id is < 0 or greater than the number of vertices in the tree.

bool vtkTree::IsLeaf

(

vtkIdType

vertex

)

Return whether the vertex is a leaf (i.e. it has no children).

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

static

Retrieve a graph from an information vector.

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

static

Retrieve a graph from an information vector.

virtual void vtkTree::ReorderChildren ( vtkIdType  parent, vtkIdTypeArray *  children  )

virtual

Reorder the children of a parent vertex. The children array must contain all the children of parent, just in a different order. This does not change the topology of the tree.

virtual bool vtkTree::IsStructureValid ( vtkGraph *  g )

protectedvirtual

Check the storage, and accept it if it is a valid tree.

Reimplemented from vtkDirectedAcyclicGraph.
