vtkDirectedAcyclicGraph Class Reference
#include <vtkDirectedAcyclicGraph.h>
Detailed Description
A rooted tree data structure.vtkDirectedAcyclicGraph is a connected directed graph with no cycles. A tree is a type of directed graph, so works with all graph algorithms.
vtkDirectedAcyclicGraph 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 vtkDirectedAcyclicGraph. This method will return false if the graph is an invalid tree.
vtkDirectedAcyclicGraph 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 vtkDirectedAcyclicGraph* vtkDirectedAcyclicGraph::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkDirectedGraph.
Reimplemented in vtkTree.
| virtual const char* vtkDirectedAcyclicGraph::GetClassName | ( | ) | [virtual] |
| static int vtkDirectedAcyclicGraph::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 vtkTypeRevisionMacro found in vtkSetGet.h.

| ) | [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.
