cfdm.DomainTopology.has_cell

DomainTopology.has_cell()

Whether the cell type has been set.

The cell type indicates the common spatial dimensionality of the cells, one of:

• 'point': A point is zero-dimensional and has no boundary

  vertices.

• 'edge': An edge is one-dimensional and corresponds to a

  line connecting two boundary vertices.

• 'face': A face is two-dimensional and corresponds to a

  surface enclosed by a set of edges.

New in version (cfdm): 1.11.0.0

Returns

bool

True if the cell type has been set, otherwise False.
