DimensionRecord
(**kwargs)¶ Bases:
object
Base class for the Python representation of database records for a
DimensionElement
.Parameters: - **kwargs
Field values for this record. Unrecognized keys are ignored. If this is the record for a
Dimension
, its primary key value may be provided with the actual name of the field (e.g. “id” or “name”), the name of theDimension
, or both. If this record class has a “timespan” attribute, “datetime_begin” and “datetime_end” keyword arguments may be provided instead of a single “timespan” keyword argument (but are ignored if a “timespan” argument is provided).
Notes
DimensionRecord
subclasses are created dynamically for eachDimensionElement
in aDimensionUniverse
, and are accessible via theDimensionElement.RecordClass
attribute. TheDimensionRecord
base class itself is pure abstract, but does not use theabc
module to indicate this because it does not have overridable methods.Record classes have attributes that correspond exactly to the
standard
fields in the related database table, plus “region” and “timespan” attributes for spatial and/or temporal elements (respectively).Instances are usually obtained from a
Registry
, but can be constructed directly from Python as well.DimensionRecord
instances are immutable.Attributes Summary
dataId
A dict-like identifier for this record’s primary keys ( DataCoordinate
).Methods Summary
toDict
(splitTimespan)Return a vanilla dict
representation of this record.Attributes Documentation
