Examples of TupleEntryChainIterator

cascading.tuple.TupleEntryChainIterator
TupleEntryChainIterator chains the given Iterators into a single Iterator.
As one iterator is completed, it will be closed and a new one will start.

Examples of cascading.tuple.TupleEntryChainIterator

    Iterator iterators[] = new Iterator[ getTaps().length ];


    for( int i = 0; i < getTaps().length; i++ )
      iterators[ i ] = new TupleIterator( getTaps()[ i ].openForRead( flowProcess ) );


    return new TupleEntryChainIterator( getSourceFields(), iterators );
    }
