U ,�] � @ s d Z G dd� de�ZdgZdS )u� An object subclass for Python 2 that gives new-style classes written in the style of Python 3 (with ``__next__`` and unicode-returning ``__str__`` methods) the appropriate Python 2-style ``next`` and ``__unicode__`` methods for compatible. Example use:: from builtins import object my_unicode_str = u'Unicode string: 孔子' class A(object): def __str__(self): return my_unicode_str a = A() print(str(a)) # On Python 2, these relations hold: assert unicode(a) == my_unicode_string assert str(a) == my_unicode_string.encode('utf-8') Another example:: from builtins import object class Upper(object): def __init__(self, iterable): self._iter = iter(iterable) def __next__(self): # note the Py3 interface return next(self._iter).upper() def __iter__(self): return self assert list(Upper('hello')) == list('HELLO') c @ s< e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zg Z d S ) � newobjectz� A magical object class that provides Python 2 compatibility methods:: next __unicode__ __nonzero__ Subclasses of this class can merely define the Python 3 methods (__next__, __str__, and __bool__). c C s$ t | d�rt| ��| �S td��d S )N�__next__z newobject is not an iterator)�hasattr�typer � TypeError��self� r �8/usr/lib/python3/dist-packages/future/types/newobject.py�next3 s znewobject.nextc C s> t | d�rt| ��| �}nt| �}t|t�r0|S |�d�S d S )N�__str__zutf-8)r r r �str� isinstanceZunicode�decode)r �sr r r � __unicode__8 s znewobject.__unicode__c C s4 t | d�rt| ��| �S t | d�r0t| ��| �S dS )N�__bool__�__len__T)r r r r r r r r � __nonzero__D s znewobject.__nonzero__c C s t | d�stS | �� S )N�__int__)r �NotImplementedr r r r r �__long__S s znewobject.__long__c C s t | �S )z= Hook for the future.utils.native() function )�objectr r r r � __native__m s znewobject.__native__N) �__name__� __module__� __qualname__�__doc__r r r r r � __slots__r r r r r ) s r N)r r r �__all__r r r r �<module> s (L
