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

Subclasses of ComposableRecordReader in org.apache.hadoop.mapreduce.lib.join

Modifier and Type	Class	Description
class	CompositeRecordReader<K extends WritableComparable<?>,V extends Writable,X extends Writable>	A RecordReader that can effect joins of RecordReaders sharing a common key type and partitioning.
class	InnerJoinRecordReader<K extends WritableComparable<?>>	Full inner join.
class	JoinRecordReader<K extends WritableComparable<?>>	Base class for Composite joins returning Tuples of arbitrary Writables.
class	MultiFilterRecordReader<K extends WritableComparable<?>,V extends Writable>	Base class for Composite join returning values derived from multiple sources, but generally not tuples.
class	OuterJoinRecordReader<K extends WritableComparable<?>>	Full outer join.
class	OverrideRecordReader<K extends WritableComparable<?>,V extends Writable>	Prefer the "rightmost" data source for this key.
class	WrappedRecordReader<K extends WritableComparable<?>,U extends Writable>	Proxy class for a RecordReader participating in the join framework.

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

Modifier and Type	Method	Description
void	CompositeRecordReader.add(ComposableRecordReader<K,? extends V> rr)	Add a RecordReader to this collection.
int	CompositeRecordReader.compareTo(ComposableRecordReader<K,?> other)	Implement Comparable contract (compare key of join or head of heap with that of another).
int	WrappedRecordReader.compareTo(ComposableRecordReader<K,?> other)	Implement Comparable contract (compare key at head of proxied RR with that of another).
