Method: Integer.unbooleanize

Defined in:
lib/wukong/extensions/emittable.rb

.unbooleanize(bool) ⇒ Object

Express boolean as 1 (true) or 0 (false). In contravention of typical ruby semantics (but in a way that is more robust for wukong-like batch processing), the number 0, the string ‘0’, nil and false are all considered false. (This also makes the method idempotent: repeated calls give same result.)
