public interface ObjectCollection<K> extends Collection<K>, ObjectIterable<K>
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[]).
Collection| Modifier and Type | Method and Description |
|---|---|
ObjectIterator<K> |
iterator()
Returns a type-specific iterator on the elements of this collection.
|
ObjectIterator<K> |
objectIterator()
Deprecated.
As of
fastutil 5, replaced by iterator(). |
<T> T[] |
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.
toArray in interface Collection<K>a - if this array is big enough, it will be used to store this collection.Collection.toArray(Object[])
