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

Subinterfaces of ResetableIterator in org.apache.hadoop.mapred.join

interface

ResetableIterator<T extends Writable> This defines an interface to a stateful Iterator that can replay elements added to it directly.

Classes in org.apache.hadoop.mapred.join that implement ResetableIterator

protected class	JoinRecordReader.JoinDelegationIterator Since the JoinCollector is effecting our operation, we need only provide an iterator proxy wrapping its operation.
protected class	MultiFilterRecordReader.MultiFilterDelegationIterator Proxy the JoinCollector, but include callback to emit.

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

Classes in org.apache.hadoop.mapreduce.lib.join that implement ResetableIterator

class	ArrayListBackedIterator<X extends Writable> This class provides an implementation of ResetableIterator.
static class	ResetableIterator.EMPTY<U extends Writable>
class	StreamBackedIterator<X extends Writable> This class provides an implementation of ResetableIterator.

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

protected ResetableIterator<V>	MultiFilterRecordReader.getDelegate() Return an iterator returning a single value from the tuple.
protected ResetableIterator<TupleWritable>	JoinRecordReader.getDelegate() Return an iterator wrapping the JoinCollector.
protected abstract ResetableIterator<X>	CompositeRecordReader.getDelegate() Obtain an iterator over the child RRs apropos of the value type ultimately emitted from this join.

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

void	CompositeRecordReader.JoinCollector.add(int id, ResetableIterator<X> i) Register a given iterator at position id.
