| Packages that use TupleWritable | |
|---|---|
| org.apache.hadoop.mapred.join | |
| Uses of TupleWritable in org.apache.hadoop.mapred.join | 
|---|
| Methods in org.apache.hadoop.mapred.join that return TupleWritable | |
|---|---|
| protected  TupleWritable | CompositeRecordReader.createInternalValue()Create a value to be used internally for joins. | 
|  TupleWritable | JoinRecordReader.createValue()Create an object of the appropriate type to be used as a value. | 
| Methods in org.apache.hadoop.mapred.join that return types with arguments of type TupleWritable | |
|---|---|
| protected  ResetableIterator<TupleWritable> | JoinRecordReader.getDelegate()Return an iterator wrapping the JoinCollector. | 
|  ComposableRecordReader<K,TupleWritable> | CompositeInputFormat.getRecordReader(InputSplit split,
                               JobConf job,
                               Reporter reporter)Construct a CompositeRecordReader for the children of this InputFormat as defined in the init expression. | 
| Methods in org.apache.hadoop.mapred.join with parameters of type TupleWritable | |
|---|---|
| protected  boolean | InnerJoinRecordReader.combine(Object[] srcs,
               TupleWritable dst)Return true iff the tuple is full (all data sources contain this key). | 
| protected abstract  boolean | CompositeRecordReader.combine(Object[] srcs,
               TupleWritable value) | 
| protected  boolean | OuterJoinRecordReader.combine(Object[] srcs,
               TupleWritable dst)Emit everything from the collector. | 
| protected  boolean | MultiFilterRecordReader.combine(Object[] srcs,
               TupleWritable dst)Default implementation offers MultiFilterRecordReader.emit(org.apache.hadoop.mapred.join.TupleWritable)every Tuple from the
 collector (the outer join of child RRs). | 
| protected  V | OverrideRecordReader.emit(TupleWritable dst)Emit the value with the highest position in the tuple. | 
| protected abstract  V | MultiFilterRecordReader.emit(TupleWritable dst)For each tuple emitted, return a value (typically one of the values in the tuple). | 
|  boolean | JoinRecordReader.next(K key,
         TupleWritable value)Emit the next set of key, value pairs as defined by the child RecordReaders and operation associated with this composite RR. |
