class cf.Domain(source=None, copy=True, _use_data=True)

Bases: cfdm.domain.Domain

A domain of the CF data model.

The domain represents a set of discrete “locations” in what generally would be a multi-dimensional space, either in the real world or in a model’s simulated world. These locations correspond to individual data array elements of a field construct

The domain is defined collectively by the following constructs of the CF data model: domain axis, dimension coordinate, auxiliary coordinate, cell measure, coordinate reference and domain ancillary constructs.

Initialization

Parameters:

source: optional

Initialize the metadata constructs from those of source.

A new domain may also be instantiated with the fromconstructs class method.

copy: bool, optional

If False then do not deep copy input parameters prior to initialization. By default arguments are deep copied.

Inspection

Methods

dump	A full description of the domain.
