cfdm.core.Domain

---

class cfdm.core.Domain(properties=None, source=None, copy=True, _use_data=True)

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 multi-dimensional 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.

Properties may also be set after initialisation with the set_properties and set_property methods.

Parameter example:

properties={'long_name': 'Domain for model'}

source: optional

Convert source, which can be any type of object, to a Domain instance.

All other parameters, apart from copy, are ignored and their values are instead inferred from source by assuming that it has the Domain API. Any parameters that can not be retrieved from source in this way are assumed to have their default value.

Note that if x is also a Domain instance then cfdm.core.Domain(source=x) is equivalent to x.copy().

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

copy: bool, optional

If True (the default) then deep copy the input parameters prior to initialisation. By default the parameters are not deep copied.
