Uses of TupleWritable in org.apache.hadoop.mapreduce.lib.join

Methods in org.apache.hadoop.mapreduce.lib.join that return TupleWritable

Modifier and Type	Method and Description
protected TupleWritable	CompositeRecordReader.createTupleWritable() Create a value to be used internally for joins.
TupleWritable	JoinRecordReader.createValue()

Methods in org.apache.hadoop.mapreduce.lib.join that return types with arguments of type TupleWritable

Modifier and Type	Method and Description
RecordReader<K,TupleWritable>	CompositeInputFormat.createRecordReader(InputSplit split, TaskAttemptContext taskContext) Construct a CompositeRecordReader for the children of this InputFormat as defined in the init expression.
protected ResetableIterator<TupleWritable>	JoinRecordReader.getDelegate() Return an iterator wrapping the JoinCollector.

Methods in org.apache.hadoop.mapreduce.lib.join with parameters of type TupleWritable

Modifier and Type	Method and Description
protected boolean	MultiFilterRecordReader.combine(Object[] srcs, TupleWritable dst) Default implementation offers MultiFilterRecordReader.emit(org.apache.hadoop.mapreduce.lib.join.TupleWritable) every Tuple from the collector (the outer join of child RRs).
protected abstract boolean	CompositeRecordReader.combine(Object[] srcs, TupleWritable value)
protected boolean	OuterJoinRecordReader.combine(Object[] srcs, TupleWritable dst) Emit everything from the collector.
protected boolean	InnerJoinRecordReader.combine(Object[] srcs, TupleWritable dst) Return true iff the tuple is full (all data sources contain this key).
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).
