Base Class

About

FrozenBase is the base class for frozendict and FrozenOrderedDict. If you wish to construct your own frozen dictionary classes, you may wish to inherit from this class.

Usage

API Reference

class cawdrey.base.FrozenBase(*args, **kwargs)

Abstract Base Class for Frozen dictionaries

Used by frozendict and FrozenOrderedDict.

Custom subclasses must implement at a minimum __init__, copy, fromkeys.

__abstractmethods__ = frozenset({'copy', '__init__'})

__class__

alias of abc.ABCMeta

__contains__(key)

__copy__(*args, **kwargs)

__delattr__

Implement delattr(self, name).

__dict__ = mappingproxy({'__module__': 'cawdrey.base', '__doc__': '\n\tAbstract Base Class for Frozen dictionaries\n\t\n\tUsed by frozendict and FrozenOrderedDict.\n\t\n\tCustom subclasses must implement at a minimum ``__init__``,\n\t``copy``, ``fromkeys``.\n\t', 'dict_cls': None, '__init__': <function FrozenBase.__init__>, 'fromkeys': <classmethod object>, '__abstractmethods__': frozenset({'copy', '__init__'}), '_abc_registry': <_weakrefset.WeakSet object>, '_abc_cache': <_weakrefset.WeakSet object>, '_abc_negative_cache': <_weakrefset.WeakSet object>, '_abc_negative_cache_version': 42})

__dir__() → list

default dir() implementation

__eq__(other)

Return self==value.

__format__()

default object formatter

__ge__

Return self>=value.

__getattribute__

Return getattr(self, name).

__getitem__(key)

__gt__

Return self>value.

__hash__ = None

__init__(*args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.

__init_subclass__()

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

__iter__()

__le__

Return self<=value.

__len__()

__lt__

Return self<value.

__module__ = 'cawdrey.base'

__ne__

Return self!=value.

__new__()

Create and return a new object. See help(type) for accurate signature.

__reduce__()

helper for pickle

__reduce_ex__()

helper for pickle

__repr__()

Return repr(self).

__reversed__ = None

__setattr__

Implement setattr(self, name, value).

__sizeof__() → int

size of object in memory, in bytes

__slots__ = ()

__str__

Return str(self).

classmethod __subclasshook__(C)

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

__weakref__

list of weak references to the object (if defined)

_abc_cache = <_weakrefset.WeakSet object>

_abc_negative_cache = <_weakrefset.WeakSet object>

_abc_negative_cache_version = 42

_abc_registry = <_weakrefset.WeakSet object>

copy(*args, **kwargs)

dict_cls = None

classmethod fromkeys(*args, **kwargs)

Returns a new dict with keys from iterable and values equal to value.

get(k[, d]) → D[k] if k in D, else d. d defaults to None.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

values() → an object providing a view on D's values
