DESCRIPTION
This trait provides native delegation methods for boolean values. A boolean is a scalar which can be 1, 0, “”, or “undef”.
DEFAULT TYPE
If you don’t provide an “isa” value for your attribute, it will default to “Bool”.
PROVIDED METHODS
None of these methods accept arguments.
• |
set |
Sets the value to 1 and returns 1.
• |
unset |
Set the value to 0 and returns 0.
• |
toggle |
Toggles the value. If it’s true, set to false, and vice versa.
Returns the new value.
• |
not |
Equivalent of ’not $value’.
