Uses of NullableTuple in org.apache.pig.backend.hadoop.executionengine.mapReduceLayer
 

Method parameters in org.apache.pig.backend.hadoop.executionengine.mapReduceLayer with type arguments of type NullableTuple
protected  void PigGenericMapReduce.ReduceWithComparator.reduce(PigNullableWritable key, Iterable<NullableTuple> tupIter, org.apache.hadoop.mapreduce.Mapper.Context context)
          The reduce function which packages the key and List<Tuple> into key, Bag<Tuple> after converting Hadoop type key into Pig type.
protected  void PigGenericMapReduce.Reduce.reduce(PigNullableWritable key, Iterable<NullableTuple> tupIter, org.apache.hadoop.mapreduce.Reducer.Context context)
          The reduce function which packages the key and List<Tuple> into key, Bag<Tuple> after converting Hadoop type key into Pig type.
protected  void PigCombiner.Combine.reduce(PigNullableWritable key, Iterable<NullableTuple> tupIter, org.apache.hadoop.mapreduce.Reducer.Context context)
          The reduce function which packages the key and List <Tuple> into key, Bag<Tuple> after converting Hadoop type key into Pig type.
protected  void DistinctCombiner.Combine.reduce(PigNullableWritable key, Iterable<NullableTuple> tupIter, org.apache.hadoop.mapreduce.Reducer.Context context)
          The reduce function which removes values.
 

Uses of NullableTuple in org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators
 

Methods in org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators that return types with arguments of type NullableTuple
 Iterator<NullableTuple> POPackageLite.getTupIter()
           
 

Methods in org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators with parameters of type NullableTuple
protected  Tuple POPackage.getValueTuple(NullableTuple ntup, int index)
           
 Tuple POPackageLite.getValueTuple(NullableTuple ntup, int index, Object key)
          Makes use of the superclass method, but this requires an additional parameter key passed by ReadOnceBag.
 

Method parameters in org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators with type arguments of type NullableTuple
 void POPackage.attachInput(PigNullableWritable k, Iterator<NullableTuple> inp)
          Attaches the required inputs
 void POMultiQueryPackage.attachInput(PigNullableWritable k, Iterator<NullableTuple> inp)
           
 

Uses of NullableTuple in org.apache.pig.data
 

Constructor parameters in org.apache.pig.data with type arguments of type NullableTuple
ReadOnceBag(POPackageLite pkg, Iterator<NullableTuple> tupIter, Object key)
          This constructor creates a bag out of an existing iterator of tuples by taking ownership of the iterator and NOT copying the elements of the iterator.
