Uses of TupleWritable in org.apache.hadoop.mapred.join

Methods in org.apache.hadoop.mapred.join that return TupleWritable

Modifier and Type	Method and Description
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

Modifier and Type	Method and Description
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

Modifier and Type	Method and Description
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 boolean	OuterJoinRecordReader.combine(Object[] srcs, TupleWritable dst) Emit everything from the collector.
protected abstract boolean	CompositeRecordReader.combine(Object[] srcs, TupleWritable value)
protected boolean	InnerJoinRecordReader.combine(Object[] srcs, TupleWritable dst) Return true iff the tuple is full (all data sources contain this key).
protected abstract V	MultiFilterRecordReader.emit(TupleWritable dst) For each tuple emitted, return a value (typically one of the values in the tuple).
protected V	OverrideRecordReader.emit(TupleWritable dst) Emit the value with the highest position 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.
