django.contrib.gis.geos.mutable_list.ListMixin

class documentation

class ListMixin:

Known subclasses: django.contrib.gis.geos.geometry.GEOSGeometry

View In Hierarchy

A base class which provides complete list interface. Derived classes must call ListMixin's __init__() function and implement the following:

function _get_single_external(self, i):
Return single item with index i for general use. The index i will always satisfy 0 <= i < len(self).
function _get_single_internal(self, i):
Same as above, but for use within the class [Optional] Note that if _get_single_internal and _get_single_internal return different types of objects, _set_list must distinguish between the two and handle each appropriately.
function _set_list(self, length, items):

Recreate the entire object.

NOTE: items may be a generator which calls _get_single_internal. Therefore, it is necessary to cache the values in a temporary:

temp = list(items)

before clobbering the original storage.

function _set_single(self, i, value):
Set the single item at index i to value [Optional] If left undefined, all mutations will result in rebuilding the object using _set_list.
function __len__(self):
Return the length
int _minlength:
The minimum legal length [Optional]
int _maxlength:
The maximum legal length [Optional]
type or tuple _allowed:
A type or tuple of allowed item types [Optional]
