      Description copied from class: AbstractLongList
      Copies (hopefully quickly) elements of this type-specific list into the given array.

      This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

      Specified by:
      getElements in interface LongList
      Overrides:
      getElements in class AbstractLongList
      Parameters:
      from - the start index (inclusive).
      a - the destination array.
      offset - the offset into the destination array where to store the first element copied.
      length - the number of elements to be copied.

    • removeElements

      public void removeElements​(int from, int to)
      Description copied from class: AbstractLongList
      Removes (hopefully quickly) elements of this type-specific list.

      This is a trivial iterator-based based implementation. It is expected that implementations will override this method with a more optimized version.

      Specified by:
      removeElements in interface LongList
      Overrides:
      removeElements in class AbstractLongList
      Parameters:
      from - the start index (inclusive).
      to - the end index (exclusive).

    • addElements

      public void addElements​(int index, long[] a, int offset, int length)
      Description copied from class: AbstractLongList
      Add (hopefully quickly) elements to this type-specific list.

      This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

      Specified by:
      addElements in interface LongList
      Overrides:
      addElements in class AbstractLongList
      Parameters:
      index - the index at which to add elements.
      a - the array containing the elements.
      offset - the offset of the first element to add.
      length - the number of elements to add.

    • setElements

      public void setElements​(int index, long[] a, int offset, int length)
      Description copied from interface: LongList
      Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by 
       
 ListIterator iter = listIterator(index);
 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.
      Specified by:
      setElements in interface LongList
      Overrides:
      setElements in class AbstractLongList
      Parameters:
      index - the index at which to start setting elements.
      a - the array containing the elements
      offset - the offset of the first element to add.
      length - the number of elements to add.
