Examples of TupleListCollector

cascading.tuple.TupleListCollector
TupleEntryCollector is a convenience class for managing a list of tuples. More specifically it can simultaneously append and modify in place elements of the list through the use of a ListIterator.

Examples of cascading.tuple.TupleListCollector

                                    new Tuple( new Double( 2.0 ) ), new Tuple( new Double( 4.0 ) ),
                                    new Tuple( new Double( -5.0 ) )};


    Fields resultFields = new Fields( "field" );


    TupleListCollector resultEntryCollector = invokeAggregator( aggregator, arguments, resultFields );


    Tuple tuple = resultEntryCollector.iterator().next();


    assertEquals( "got expected value after aggregate", 1.0, tuple.getDouble( 0 ), 0.0d );
    }
