* @class vtkUnstructuredGridBaseAlgorithm
|
|
* @brief Superclass for algorithms that
|
|
* produce only vtkUnstructureGridBase subclasses as output
|
|
*
|
|
* vtkUnstructuredGridBaseAlgorithm is a convenience class to make writing
|
|
* algorithms easier. 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 classes
|
|
* constructor for the default. This class also provides a FillInputPortInfo
|
|
* method that by default says that all inputs will be UnstructuredGridBase. If
|
|
* that isn't the case then please override this method in your subclass.
