// .NAME vtkArrayDataAlgorithm - Superclass for algorithms that produce
|
|
// vtkArrayDatas as output
|
|
//
|
|
// .SECTION Description
|
|
// vtkArrayDataAlgorithm 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 vtkArrayData. If that
|
|
// isn't the case then please override this method in your subclass.
|
