class Boolean b whereSource

A class for boolean algebras. Instances of this class are expected to obey all the laws of boolean algebra.

Minimal complete definition: true or false, not or <-->, || or &&.


true :: bSource

Truth value, defined as the top of the bounded lattice

false :: bSource

False value, defined as the bottom of the bounded lattice.

not :: b -> bSource

Logical negation.

(&&) :: b -> b -> bSource

Logical conjunction. (infxr 3)

(||) :: b -> b -> bSource

Logical inclusive disjunction. (infixr 2)

xor :: b -> b -> bSource

Logical exclusive disjunction. (infixr 1)

(-->) :: b -> b -> bSource

Logical implication. (infixr 1)

(<-->) :: b -> b -> bSource

Logical biconditional. (infixr 1)

fromBool :: Boolean b => Bool -> bSource

Injection from Bool into a boolean algebra.
