public interface ReferenceCollection<K>
A type-specific Collection
; provides some additional methods
that use polymorphism to avoid (un)boxing.
Additionally, this class defines strengthens (again) iterator()
and defines
a slightly different semantics for toArray(Object[])
.

ObjectIterator<K> |
iterator()
Returns a type-specific iterator on the elements of this collection. |

Deprecated. As of fastutil 5, replaced by iterator() . |

toArray(T[] a)
Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array. |

ObjectIterator<K> iterator()
Note that this specification strengthens the one given in
Iterable.iterator()
, which was already
strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection
.

Warning: Note that, contrarily to Collection.toArray(Object[])
, this
methods just writes all elements of this collection: no special
value will be added after the last one.
