Domain.domain_axes(*identities, **filter_kwargs)[source]

Return domain axis constructs.

New in version (cfdm): 1.7.0

identities: tuple, optional

Select domain axis constructs that have an identity, defined by their identities methods, that matches any of the given values.

Additionally, the values are matched against construct identifiers, with or without the 'key%' prefix.

Additionally, if for a given value, f.coordinates(value, filter_by_naxes=(1,)) returns 1-d coordinate constructs that all span the same domain axis construct then that domain axis construct is selected. See coordinates for details.

Additionally, if there is an associated Field data array and a value matches the integer position of an array dimension, then the corresponding domain axis construct is selected.

If no values are provided then all domain axis constructs are selected.

A value may be any object that can match via the == operator, or a re.Pattern object that matches via its search method.

Note that in the output of a dump method or print call, a construct is always described by an identity that will select it.

filter_kwargs: optional

Keyword arguments as accepted by Constructs.filter that define additional construct selection criteria. Also to configure the returned value.

New in version (cfdm):


The selected constructs in a new Constructs object, unless modified by any filter_kwargs parameters. The returned object will contain no constructs if none were selected.
