Interface PartiallyOrderedSet.Ordering<E>

  • Type Parameters:
    E - Element type
    Enclosing class:
    PartiallyOrderedSet<E>
    public static interface PartiallyOrderedSet.Ordering<E>
    Ordering relation.

    To obey the constraints of the partially-ordered set, the function must be consistent with the reflexive, anti-symmetric, and transitive properties required by a partially ordered set.

    For instance, if ordering(foo, foo) returned false for any not-null value of foo, it would violate the reflexive property.

    If an ordering violates any of these required properties, the behavior of a PartiallyOrderedSet is unspecified. (But mayhem is likely.)
