// .NAME vtkDirectedGraphAlgorithm - Superclass for algorithms that produce only directed graph as output
|
|
//
|
|
// .SECTION Description
|
|
// vtkDirectedGraphAlgorithm is a convenience class to make writing algorithms
|
|
// easier. It is also designed to help transition old algorithms to the new
|
|
// pipeline edgehitecture. 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).
|
|
|
|
//
|
|
// .SECTION Thanks
|
|
// Thanks to Patricia Crossno, Ken Moreland, Andrew Wilson and Brian Wylie from
|
|
// Sandia National Laboratories for their help in developing this class.
