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();
   }

Create an empty cell. The user is responsible for deleting it.

Postcondition:
result_exists: result!=0

Implemented in vtkBridgeCellIterator, and vtkBridgeCellIteratorStrategy.

virtual void vtkGenericCellIterator::GetCell ( vtkGenericAdaptorCell c)
pure virtual

Get the cell at current position. The cell should be instantiated with the NewCell() method.

Precondition:
not_at_end: !IsAtEnd()
c_exists: c!=0 THREAD SAFE

Implemented in vtkBridgeCellIterator, vtkBridgeCellIteratorOnCellBoundaries, vtkBridgeCellIteratorOne, vtkBridgeCellIteratorOnCellList, and vtkBridgeCellIteratorOnDataSet.

virtual vtkGenericAdaptorCell* vtkGenericCellIterator::GetCell ( )
pure virtual

Get the cell at the current traversal position. NOT THREAD SAFE

Precondition:
not_at_end: !IsAtEnd()
Postcondition:
result_exits: result!=0

Implemented in vtkBridgeCellIterator, vtkBridgeCellIteratorOnCellBoundaries, vtkBridgeCellIteratorOne, vtkBridgeCellIteratorOnCellList, and vtkBridgeCellIteratorOnDataSet.

virtual void vtkGenericCellIterator::Next ( )
pure virtual

Move the iterator to the next position in the list.

Precondition:
not_at_end: !IsAtEnd()

Implemented in vtkBridgeCellIterator, vtkBridgeCellIteratorOnCellBoundaries, vtkBridgeCellIteratorOne, vtkBridgeCellIteratorOnCellList, and vtkBridgeCellIteratorOnDataSet.
