# `BoundFactory`

#### This will bind the attribute to whatever is given by `factory_class`. This factory should be a callable with the signature `factory_class(added_class, attr_name, *args, **kw)`.

The BoundFactory class is accessible via the `sqlobject.boundattributes` module.

The factory will be reinvoked (and the attribute rebound) for every subclassing.

## Attributes

#### a `__addtoclass__`

    <bound class method BoundFactory.__addtoclass__>

#### a `factory_class`

    None

#### a `singleton`

    <bound class method BoundFactory.singleton>

#### a `__mutableattributes__`

    ()

#### a `__restrict_attributes__`

    None

#### a `declarative_count`

    2

## Methods

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

default object formatter

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

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

#### f `__classinit__(cls, new_attrs)` ...

#### f `__instanceinit__(self, new_attrs)` ...

#### f `set_object(cls, added_class, attr_name, obj)` ...

#### f `make_object(cls, added_class, attr_name, *args, **kw)` ...

#### f `__init__(self, *args, **kw)` ...

#### f `__call__(self, *args, **kw)` ...
