Detailed Description

Superclass for algorithms that produce only graph as output.

vtkGraphAlgorithm is a convenience class to make writing algorithms easier. It is also designed to help transition old algorithms to the new pipeline architecture. There are some assumptions and defaults made by this class you should be aware of. This class defaults such that your filter will have one input port and one output port. If that is not the case simply change it with SetNumberOfInputPorts etc. See this class constructor for the default. This class also provides a FillInputPortInfo method that by default says that all inputs will be Graph. If that isn't the case then please override this method in your subclass. You should implement the subclass's algorithm into RequestData( request, inputVec, outputVec).

Reimplemented from vtkAlgorithm.

Get the output data object for a port on this algorithm.

Definition at line 69 of file vtkGraphAlgorithm.h.

Get the output data object for a port on this algorithm.

Assign a data object as input. Note that this method does not establish a pipeline connection. Use SetInputConnection() to setup a pipeline connection.

void vtkGraphAlgorithm::SetInputData ( int  index,
vtkDataObject obj 
)

Assign a data object as input. Note that this method does not establish a pipeline connection. Use SetInputConnection() to setup a pipeline connection.

virtual int vtkGraphAlgorithm::RequestInformation ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

Reimplemented in vtkCollectGraph.

virtual int vtkGraphAlgorithm::RequestDataObject ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]
virtual int vtkGraphAlgorithm::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented in vtkCollectGraph.

virtual int vtkGraphAlgorithm::FillOutputPortInformation ( int  port,
vtkInformation info 
) [protected, virtual]

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkAlgorithm.

Reimplemented in vtkPBGLShortestPaths, vtkPBGLCollectGraph, vtkPBGLBreadthFirstSearch, vtkBoostBreadthFirstSearch, vtkCollapseVerticesByArray, vtkBoostBetweennessClustering, vtkPBGLMinimumSpanningTree, vtkPBGLVertexColoring, and vtkPBGLConnectedComponents.

virtual int vtkGraphAlgorithm::FillInputPortInformation ( int  port,
