Detailed Description

provides thread-safe access to cells

vtkGenericCell is a class that provides access to concrete types of cells. It's main purpose is to allow thread-safe access to cells, supporting the vtkDataSet::GetCell(vtkGenericCell *) method. vtkGenericCell acts like any type of cell, it just dereferences an internal representation. The SetCellType() methods use #define constants; these are defined in the file vtkCellType.h.
