Enclosing class:
ByteIterators

public static class ByteIterators.EmptyIterator
extends AbstractByteListIterator
implements java.io.Serializable, java.lang.Cloneable

A class returning no elements and a type-specific iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.

 boolean hasNext()
           
 boolean hasPrevious()
          Returns whether there is a previous element.
 byte nextByte()
          Delegates to the corresponding generic method.
