Interface Ord.Definition<A>

All Superinterfaces:

Equal.Definition<A>, Semigroup.Definition<A>

All Known Subinterfaces:

Ord.AltDefinition<A>

Enclosing class:

Ord<A>

public static interface Ord.Definition<A>
extends Equal.Definition<A>, Semigroup.Definition<A>

Primitives functions of Ord: minimal definition and overridable methods.
