cfdm.core.Domain¶

class
cfdm.core.
Domain
(properties=None, source=None, copy=True, _use_data=True)[source]¶ Bases:
cfdm.core.mixin.fielddomain.FieldDomain
,cfdm.core.abstract.properties.Properties
A domain construct of the CF data model.
The domain represents a set of discrete “locations” in what generally would be a multidimensional space, either in the real world or in a model’s simulated world. The data array elements of a field construct correspond to individual location of a domain.
The domain construct 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; as well as properties to describe the domain.
New in version (cfdm): 1.7.0
Initialisation
 Parameters
 properties:
dict
, optional Set descriptive properties. The dictionary keys are property names, with corresponding values. Ignored if the source parameter is set.
Properties may also be set after initialisation with the
set_properties
andset_property
methods. Parameter example:
properties={'long_name': 'Domain for model'}
 source: optional
Initialise the metadata constructs from those of source.
Note that if source is a
Domain
instance thencfdm.core.Domain(source=source)
is equivalent tosource.copy()
.A new domain may also be instantiated with the
fromconstructs
class method. copy:
bool
, optional If True (the default) deep copy input parameters prior to initialisation. If False arguments are not deep copied.
