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({'__init__', 'copy'})

__annotations__ = {'dict_cls': typing.Union[typing.Type, NoneType]}

__args__ = None

__contains__(key)

Return type

Any

__eq__(other)

Return self==value.

__extra__ = None

__getitem__(key)

Return type

Any

abstract __init__(*args, **kwargs)

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

__iter__()

__len__()

Return type

int

__module__ = 'cawdrey.base'

static __new__(cls, *args, **kwds)

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

_gorg

alias of FrozenBase

abstract copy(*args, **kwargs)

dict_cls: Optional[Type] = 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
