* @brief Default cell iterator for

* vtkMappedUnstructuredGrid.
|
|
*
|
|
*
|
|
* This class is used by default for vtkMappedUnstructedGrid instances. It
|
|
* uses random access for data lookups. Custom vtkCellIterator implementations
|
|
* should be used instead when random-access is inefficient.
