Special Methods

Unpickler.__delattr__(name, /)

Implement delattr(self, name).

Unpickler.__dir__()

Default dir() implementation.

Unpickler.__eq__(value, /)

Return self==value.

Unpickler.__format__(format_spec, /)

Default object formatter.

Unpickler.__ge__(value, /)

Return self>=value.

Unpickler.__getattribute__(name, /)

Return getattr(self, name).

Unpickler.__gt__(value, /)

Return self>value.

Unpickler.__hash__()

Return hash(self).

Unpickler.__init__(xml_doc=None)

Unpickler.__init_subclass__()

This method is called when a class is subclassed.

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

Unpickler.__le__(value, /)

Return self<=value.

Unpickler.__lt__(value, /)

Return self<value.

Unpickler.__ne__(value, /)

Return self!=value.

Unpickler.__new__(**kwargs)

Unpickler.__reduce__()

Helper for pickle.

Unpickler.__reduce_ex__(protocol, /)

Helper for pickle.

Unpickler.__repr__()

Return repr(self).

Unpickler.__setattr__(name, value, /)

Implement setattr(self, name, value).

Unpickler.__sizeof__()

Size of object in memory, in bytes.

Unpickler.__str__()

Return str(self).

Unpickler.__subclasshook__()

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).
