public final class SetAddCodec
extends Object
Adds the specified element to this set if it is not already present (optional operation).
If this set already contains the element, the call leaves the set unchanged and returns false.In combination with
the restriction on constructors, this ensures that sets never contain duplicate elements.
The stipulation above does not imply that sets must accept all elements; sets may refuse to add any particular
element, including null, and throw an exception, as described in the specification for Collection
Individual set implementations should clearly document any restrictions on the elements that they may contain.
