Classes of the `cf` module¶

Field classes¶

`cf.Field`	A field construct according to the CF data model.
`cf.FieldList`	An ordered sequence of fields.

`cf.AncillaryVariables`	A sequence of ancillary variable fields stored in a list-like object.
`cf.AuxiliaryCoordinate`	A CF auxiliary coordinate construct.
`cf.CellMeasure`	A CF cell measure construct containing information that is needed about the size, shape or location of the field’s cells.
`cf.CellMethods`	A CF cell methods object to describe the characteristic of a field that is represented by cell values.
`cf.CoordinateBounds`	A CF coordinate’s bounds object containing cell boundaries or intervals of climatological time.
`cf.CoordinateReference`	A CF coordinate reference construct.
`cf.Data`	An N-dimensional data array with units and masked values.
`cf.DimensionCoordinate`	A CF dimension coordinate construct.
`cf.Domain`	Completely describe a field’s coordinate system (domain).
`cf.Flags`	Self-describing CF flag values.
`cf.Units`	Store, combine and compare physical units and convert numeric values to different units.

`cf.Datetime`	A date-time object which supports CF calendars.
`cf.Query`	Store a query operation.
`cf.TimeDuration`	A duration of time.

`cf.Coordinate`	Base class for a CF dimension or auxiliary coordinate construct.
`cf.Dict`	A dictionary-like object with attributes.
`cf.List`	A list-like object with attributes.
`cf.Variable`	Base class for storing a data array with metadata.

The classes defined by the cf package inherit as follows:

This inheritance diagrams show, for example:

cf.Field and cf.DimensionCoordinate objects have all of the features of a cf.Variable object, e.g. they may have a data array and CF properties.
cf.FieldList objects are mutable, iterable objects.
cf.CoordinateReference objects are mutable, mapping objects.
