This method is used both when an enum class is given a value to match to an enumeration member (i.e. Color(3)) and for the functional API (i.e. Color = Enum('Color', names='red green blue')). When used for the functional API: `module`, if set, will be stored in the new class' __module__ attribute; `type`, if set, will be mixed in as the first base class. Note: if `module` is not set this routine will attempt to discover the calling module by walking the frame stack; if this is unsuccessful the resulting class will not be pickleable. t moduleRP N( R RO t _create_( R% R t namesR| RP ( ( s1 /usr/lib/python2.7/site-packages/enum/__init__.pyt __call__9 s c C s t | | � o | j | j k S( N( R` R R] ( R% t member( ( s1 /usr/lib/python2.7/site-packages/enum/__init__.pyt __contains__N s c C s? | | j k r% t d | j � � n t t | � j | � d S( Ns %s: cannot delete Enum member.( R] R R R( R0 t __delattr__( R% t attr( ( s1 /usr/lib/python2.7/site-packages/enum/__init__.pyR� Q s c C s d d d d g | j S( Nt __class__R t __members__R ( R\ ( R ( ( s1 /usr/lib/python2.7/site-packages/enum/__init__.pyt __dir__Y s c C s | j j � S( s� Returns a mapping of member name->value.
