Change constructs access API for consistency #204
Description
This enhancements imports changes from cfdm v1.8.9.0: NCAS-CMS/cfdm#132 by making the *identity, **filter_kwargs API available to construct selection methods:
>>> import cf
>>> f = cf.example_field(1)
>>> f.domain_axes(filter_by_size=(cf.gt(1),))
<CF Constructs: domain_axis(2)>
>>> f.dimension_coordinates('X', 'Y')
<CF Constructs: dimension_coordinate(2)>
>>> f.coordinates('X', 'Y')
<CF Constructs: auxiliary_coordinate(2), dimension_coordinate(2)>
>>> f.coordinates('X', 'Y', filter_by_naxes=(1,))
<CF Constructs: dimension_coordinate(2)>Consequences
The only possibly bad effect that this could have is for the default argument to be consumed by the *identity arguments if it is given as a positional parameter. For example, to Specify a default of None:
>>> f.construct('altitude', None) # ok at v3.8.0
>>> f.construct('altitude', None) # NOT ok with proposed change
>>> f.construct('altitude', default=None) # ok with proposed change and at v3.8.0Regardless of this potential for code breaking, I think this change will be beneficial.
