DESCRIPTION

This provides a simple boolean attribute, which supports most of the basic math operations.

These methods are implemented in Moose::Meta::Attribute::Native::MethodProvider::Bool. It is important to note that all those methods do in place modification of the value stored in the attribute.

set

unset

Set the value to 0.

toggle

Toggles the value. If it's true, set to false, and vice versa.
