the specified Collection. When
the given collection is null,
returns null.collection - the (possibly null) Collection to wrapLongCollection wrapping the given
collection, or null when collection is
null.protected Collection getCollection()
public boolean add(long element)
LongCollectiontrue
iff I changed as a result of this call.
If a collection refuses to add the specified
element for any reason other than that it already contains
the element, it must throw an exception (rather than
simply returning false). This preserves the invariant
that a collection always contains the specified element after
this call returns.add in interface LongCollectionelement - the value whose presence within me is to be ensuredtrue iff I changed as a result of this callpublic boolean addAll(LongCollection c)
LongCollectionAdds all of the elements in the
specified collection to me (optional operation).addAll in interface LongCollectionc - the collection of elements whose presence within me is to

LongCollectionsize.
The returned array will be independent of me,
so that callers may modify that
returned array without modifying this collection.
When I guarantee the order in which
elements are returned by an iterator,
the returned array will contain elements in the
same order.toArray in interface LongCollectionpublic long[] toArray(long[] dest)
