Interface ByteList

All Superinterfaces:
ByteCollection, ByteIterable, Collection<Byte>, Comparable<List<? extends Byte>>, Iterable<Byte>, List<Byte>
All Known Implementing Classes:
AbstractByteList, AbstractByteList.ByteSubList, ByteArrayList, ByteLists.EmptyList, ByteLists.Singleton, ByteLists.SynchronizedList, ByteLists.SynchronizedRandomAccessList, ByteLists.UnmodifiableList, ByteLists.UnmodifiableRandomAccessList
public interface ByteList
extends List<Byte>, Comparable<List<? extends Byte>>, ByteCollection
A type-specific List; provides some additional methods that use polymorphism to avoid (un)boxing.

Note that this type-specific interface extends Comparable: it is expected that implementing classes perform a lexicographical comparison using the standard operator "less then" for primitive types, and the usual compareTo() method for objects.

Additionally, this interface strengthens listIterator(), listIterator(int) and subList(int,int).

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.

    • iterator

      ByteListIterator iterator()
      Returns a type-specific iterator on the elements of this list.

      Note that this specification strengthens the one given in List.iterator(). It would not be normally necessary, but Iterable.iterator() is bizarrily re-specified in List.

      Specified by:
      iterator in interface ByteCollection

      ByteList subList​(int from, int to)
      Returns a type-specific view of the portion of this list from the index from, inclusive, to the index to, exclusive.

      Note that this specification strengthens the one given in List.subList(int,int).

      See Also:
      List.subList(int,int)

    • size

      void size​(int size)
      Sets the size of this list.

 int i = 0;
 while (i < length) {
   iter.next();
   iter.set(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 array containing the elements
      offset - the offset of the first element to add.
