int SMDS_Downward::addCell ( int  vtkId = -1 )

protectedinherited

Give or create an entry for downward connectivity structure relative to a cell.

If the entry already exists, just return its id, otherwise, create it. The internal storage memory is allocated if needed. The SMDS_UnstructuredGrid::_cellIdToDownId vector is completed for vtkUnstructuredGrid cells.

Parameters

vtkId

for a vtkUnstructuredGrid cell or -1 (default) for a created downward cell.

Returns

the rank in downward[vtkType] structure.

Parameters

lowCellId	index of the children cell to add (dimension n-1)
aType	vtk cell type of the cell to add (needed to find the SMDS_Downward structure containing the cell to add).

Actual implementation is done in derived methods.

Parameters

cellId	index of the children cell (dimension n) in the downward structure relative to a vtk cell type.
upCellId	index of the parent cell to add (dimension n+1)
aType	vtk cell type of the cell to add (needed to find the SMDS_Downward structure containing the cell to add).
