cfdm.core.InteriorRing


class cfdm.core.InteriorRing(properties=None, data=None, source=None, copy=True, _use_data=True)[source]

Bases: cfdm.core.abstract.propertiesdata.PropertiesData

An interior ring array with properties.

If a cell is composed of multiple polygon parts, an individual polygon may define an “interior ring”, i.e. a region that is to be omitted from, as opposed to included in, the cell extent. In this case an interior ring array is required that records whether each polygon is to be included or excluded from the cell, and is supplied by an interior ring variable in CF-netCDF. The interior ring array spans the same domain axis constructs as its coordinate array, with the addition of an extra dimension that indexes the parts for each cell. For example, a cell describing the land area surrounding a lake would require two polygon parts: one defines the outer boundary of the land area; the other, recorded as an interior ring, is the lake boundary, defining the inner boundary of the land area.

Initialisation

Parameters
properties: dict, optional

Set descriptive properties. The dictionary keys are property names, with corresponding values. Ignored if the source parameter is set.

Properties may also be set after initialisation with the set_properties and set_property methods.

Parameter example:

properties={'standard_name': 'altitude'}

data: data_like, optional

Set the data. Ignored if the source parameter is set.

A data_like object is any object that can be converted to a Data object, i.e. numpy array_like objects, Data objects, and cfdm.core instances that contain Data objects.

The data also may be set after initialisation with the set_data method.

source: optional

Initialise the properties and data from those of source.

Note that if source is a InteriorRing instance then cfdm.core.InteriorRing(source=source) is equivalent to source.copy().

copy: bool, optional

If False then do not deep copy input parameters prior to initialisation. By default arguments are deep copied.
