Longfei Cong,

	You can find the documentation for this class here:

http://www.vtk.org/doc/nightly/html/classvtkUnstructuredGrid.html

You can use for instance:

vtkCellArray * 	GetCells ()

to retrieve the cellArray.

	BTW if you scroll this page, you'll find test and example of use of
this class:
