Detailed Description

iterator used to traverse cells

This class (and subclasses) are used to iterate over cells. Use it only in conjunction with vtkGenericDataSet (i.e., the adaptor framework).

Typical use is:

 vtkGenericDataSet *dataset;
 vtkGenericCellIterator *it = dataset->NewCellIterator(2);
 for (it->Begin(); !it->IsAtEnd(); it->Next());
   {
   spec=it->GetCell();
   }
