  • Method Details

    • yield

      protected U yield(BasicEMap.Entry<K,V> entry)
      Called to yield the iterator result for the entry. This implementation returns the entry itself.
      Parameters:
      entry - the entry.
      Returns:
      the iterator result for the entry.

    • scan

      protected void scan()
      Scans to the new entry.

    • hasNext

      public boolean hasNext()
      Returns whether there are more objects.
      Specified by:
      hasNext in interface Iterator<U>
      Returns:
      whether there are more objects.

    • next

      public U next()
      Returns the next object and advances the iterator.
      Specified by:
      next in interface Iterator<U>
      Returns:
      the next object.
      Throws:
      NoSuchElementException - if the iterator is done.

    • remove

      public void remove()
      Removes the entry of the last object returned by next() from the map, it's an optional operation.
      Specified by:
