Examples of org.hibernate.util.JoinedIterator

org.hibernate.util.JoinedIterator
An JoinedIterator is an Iterator that wraps a number of Iterators. This class makes multiple iterators look like one to the caller. When any method from the Iterator interface is called, the JoinedIterator will delegate to a single underlying Iterator. The JoinedIterator will invoke the Iterators in sequence until all Iterators are exhausted.

    iterators.add( properties.iterator() );
    for ( int i = 0; i < joins.size(); i++ ) {
      Join join = ( Join ) joins.get( i );
      iterators.add( join.getPropertyIterator() );
    }
    return new JoinedIterator( iterators );
  }
