Enclosing class:
ByteIterators
public abstract static class ByteIterators.AbstractIndexBasedListIterator
extends ByteIterators.AbstractIndexBasedIterator
implements ByteListIterator
A skeletal implementation for a list-iterator backed by an index-based data store. High performance concrete implementations (like the main ListIterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.

This class is only appropriate for sequences that are at most Integer.MAX_VALUE long. If your backing data store can be bigger then this, consider the equivalently named class in the type specific BigListSpliterators class.

As the abstract methods in this class are used in inner loops, it is generally a good idea to override the class as final as to encourage the JVM to inline them (or alternatively, override the abstract methods as final).

  • Method Details

    • hasPrevious

      public boolean hasPrevious()
      Specified by:
      hasPrevious in interface it.unimi.dsi.fastutil.BidirectionalIterator<java.lang.Byte>
      Specified by:
      hasPrevious in interface java.util.ListIterator<java.lang.Byte>

    • previousByte

      public byte previousByte()
      Description copied from interface: ByteBidirectionalIterator
      Returns the previous element as a primitive type.
      Specified by:
      previousByte in interface ByteBidirectionalIterator
      Returns:
      the previous element in the iteration.
      See Also:
      ListIterator.previous()

    • nextIndex

      public int nextIndex()
      Specified by:
      nextIndex in interface java.util.ListIterator<java.lang.Byte>

    • previousIndex

      public int previousIndex()
      Specified by:
      previousIndex in interface java.util.ListIterator<java.lang.Byte>

    • add

      public void add​(byte k)
      Description copied from interface: ByteListIterator
      Inserts the specified element into the list (optional operation).

      This default implementation just throws an UnsupportedOperationException.

      Specified by:
      add in interface ByteListIterator
      Parameters:
      k - the element to insert.
      See Also:
      ListIterator.add(Object)

    • set

      public void set​(byte k)
      Description copied from interface: ByteListIterator
      Replaces the last element returned by ByteListIterator.next() or ByteListIterator.previous() with the specified element (optional operation).
      Specified by:
      set in interface ByteListIterator
      Parameters:
      k - the element used to replace the last element returned.

      This default implementation just throws an UnsupportedOperationException.

      See Also:
      ListIterator.set(Object)

    • back

      public int back​(int n)
      Description copied from interface: ByteBidirectionalIterator
      Moves back for the given number of elements.

      The effect of this call is exactly the same as that of calling ByteBidirectionalIterator.previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

      Specified by:
      back in interface ByteBidirectionalIterator
      Specified by:
      back in interface it.unimi.dsi.fastutil.objects.ObjectBidirectionalIterator<java.lang.Byte>
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      ByteBidirectionalIterator.previous()
