# `classinstancemethod`

#### Acts like a class method when called from a class, like an instance method when called by an instance. The method should take two arguments, 'self' and 'cls'; one of these will be None depending on how the method was called.

The classinstancemethod class is accessible via the `sqlobject.declarative` module.

## Methods

#### f `__sizeof__(...)` ...

__sizeof__() -> int size of object in memory, in bytes

#### f `__format__(...)` ...

default object formatter

#### f `__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).

#### f `__init__(self, func)` ...

#### f `__get__(self, obj, type=None)` ...
