public abstract class AbstractShortBigList
extends AbstractShortCollection
implements ShortBigList, ShortStack
An abstract class providing basic methods for big lists implementing a type-specific big list interface.

Most of the methods in this class are optimized with the assumption that the List will have have constant-time random access. If this is not the case, you should probably at least override listIterator(long) and the xAll() methods (such as addAll(long, java.util.Collection<? extends java.lang.Short>)) with a more appropriate iteration scheme. Note the subList(long, long) method is cognizant of random-access or not, so that need not be reimplemented.

      Specified by:
      getElements in interface ShortBigList
      Parameters:

 while (i < length) {
   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.
