Constructs
(auxiliary_coordinate=None, dimension_coordinate=None, domain_ancillary=None, field_ancillary=None, cell_measure=None, coordinate_reference=None, domain_axis=None, cell_method=None, source=None, copy=True, _use_data=True, _view=False, _ignore=())[source]¶ Bases:
cfdm.core.abstract.container.Container
A container for metadata constructs.
The following metadata constructs can be included:
auxiliary coordinate constructs
coordinate reference constructs
cell measure constructs
dimension coordinate constructs
domain ancillary constructs
domain axis constructs
cell method constructs
field ancillary constructs
The container is used by used by
Field
andDomain
instances.The container is like a dictionary in many ways, in that it stores key/value pairs where the key is the unique construct key with corresponding metadata construct value, and provides some of the usual dictionary methods.
New in version (cfdm): 1.7.0
Initialisation
- Parameters
- auxiliary_coordinate:
str
, optional The base name for keys of auxiliary coordinate constructs.
- Parameter example:
auxiliary_coordinate='auxiliarycoordinate'
- dimension_coordinate:
str
, optional The base name for keys of dimension coordinate constructs.
- Parameter example:
dimension_coordinate='dimensioncoordinate'
- domain_ancillary:
str
, optional The base name for keys of domain ancillary constructs.
- Parameter example:
domain_ancillary='domainancillary'
- field_ancillary:
str
, optional The base name for keys of field ancillary constructs.
- Parameter example:
field_ancillary='fieldancillary'
- cell_measure:
str
, optional The base name for keys of cell measure constructs.
- Parameter example:
cell_measure='cellmeasure'
- coordinate_reference:
str
, optional The base name for keys of coordinate reference constructs.
- Parameter example:
coordinate_reference='coordinatereference'
- domain_axis:
str
, optional The base name for keys of domain axis constructs.
- Parameter example:
domain_axis='domainaxis'
- cell_method:
str
, optional The base name for keys of cell method constructs.
- Parameter example:
cell_method='cellmethod'
- source: optional
Initialise the construct keys and contained metadata constructs from those of source.
- copy:
bool
, optional If False then do not deep copy metadata constructs from those of source prior to initialisation. By default such metadata constructs are deep copied.
- _ignore: sequence of
str
, optional Ignores the given construct types.
- Parameter example:
_ignore=('cell_method', 'field_ancillary')
