Objects of the univ.Boolean class

Instances of univ.Boolean class partially implement Python numeric object protocol by means of the following additional methods:

__and__(value)

__or__(value)

__xor__(value)

These methods implement the binary arithmetic operations (&, ^, |) against the value and return a instance of Boolean object initialized to the result of the arithmetic operation.

__rand__(value)

__ror__(value)

__rxor__(value)

These methods implement the binary arithmetic operations (&, ^, |) against the value with reflected (swapped) operands, and return a instance of Boolean object initialized to the result of the arithmetic operation.

The folowing set of methods can be called only by Python version 1.6 and later.

__iand__(value)

__ior__(value)

__ixor__(value)

These methods implement in-place arithmetic operations (&=, ^=, |=) against the value and return an instance of ourselves (self).
