public abstract static class Sets.SetView<E> extends AbstractSet<E>
SetView
; typically, you either use it
as a plain Set
, or immediately invoke immutableCopy()
or
copyInto(S)
and forget the SetView
itself.Modifier and Type | Method and Description |

<S extends Set<E>> |
copyInto(S set)

Warning: this may have unexpected results if a backing set of
this view uses a nonstandard notion of equivalence, for example if it is
a TreeSet
using a comparator that is inconsistent with Object.equals(Object)
.
