Interface LongBigList

All Superinterfaces:
BigList<Long>, Collection<Long>, Comparable<BigList<? extends Long>>, Iterable<Long>, LongCollection, LongIterable, Size64
All Known Implementing Classes:
AbstractLongBigList, AbstractLongBigList.LongRandomAccessSubList, AbstractLongBigList.LongSubList, LongBigArrayBigList, LongBigLists.EmptyBigList, LongBigLists.ListBigList, LongBigLists.Singleton, LongBigLists.SynchronizedBigList, LongBigLists.UnmodifiableBigList, LongMappedBigList
public interface LongBigList extends BigList<Long>, LongCollection, Comparable<BigList<? extends Long>>
A type-specific BigList; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens iterator(), listIterator(), listIterator(long) and subList(long,long).

Besides polymorphic methods, this interfaces specifies methods to copy into an array or remove contiguous sublists. Although the abstract implementation of this interface provides simple, one-by-one implementations of these methods, it is expected that concrete implementation override them with optimized versions.

    • spliterator

      default LongSpliterator spliterator()
      Returns a type-specific spliterator on the elements of this big-list.

      BigList spliterators must report at least Spliterator.SIZED and Spliterator.ORDERED.

      See List.spliterator() for more documentation on the requirements of the returned spliterator (despite BigList not being a List, most of the same requirements apply.

      Specified by:
      spliterator in interface Collection<Long>
      Specified by:
      spliterator in interface Iterable<Long>
      Specified by:
      spliterator in interface LongCollection
      Specified by:
      spliterator in interface LongIterable
      Returns:
      a type-specific spliterator on the elements of this collection.
      Since:
      8.5.0
      API Notes:
      This is generally the only spliterator method subclasses should override.
      Implementation Specification:
      The default implementation returns a late-binding spliterator (see Spliterator for documentation on what binding policies mean).
      • For RandomAccess lists, this will return a spliterator that calls the type-specific get(long) method on the appropriate indexes.
      • Otherwise, the spliterator returned will wrap this instance's type specific iterator().

      In either case, the spliterator reports Spliterator.SIZED, Spliterator.SUBSIZED, and Spliterator.ORDERED.

      Implementation Notes:
      As the non-RandomAccess case is based on the iterator, and Iterator is an inherently linear API, the returned spliterator will yield limited performance gains when run in parallel contexts, as the returned spliterator's trySplit() will have linear runtime.

      For RandomAccess lists, the parallel performance should be reasonable assuming get(long) is truly constant time like RandomAccess suggests.

      from - the starting element (inclusive).
      to - the ending element (exclusive).
      Returns:
      a big sublist view of this big list.
      See Also:
      API Notes:
      This specification strengthens the one given in BigList.subList(long,long).

   iter.next();
   iter.set(BigArrays.get(a, offset + i++);
 }
      However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

      index - the index at which to start setting elements.
      a - the big array containing the elements.
      offset - the offset of the first element to add.
