# `Boolean`

#### A bool class that also understands some special string keywords (yes/no, true/false, on/off, 1/0)

The Boolean class is accessible via the `sqlobject.dbconnection` 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__(...)` ...

x.__init__(...) initializes x; see help(type(x)) for signature
