.class
SkippingIterator
Every call toSkippingIterator.next()
andSkippingIterator.seek(Range, Collection, boolean)

.class
SortedKeyIterator
class
SortedMapIterator
A simple iterator over a Java SortedMap Note that this class is intended as an in-memory replacement for RFile$Reader, so its behavior reflects the same assumptions; namely, that this iterator is not responsible for respecting the columnFamilies passed into seek().class
SynchronizedServerFilter
A SortedKeyValueIterator similar toServerFilter
but with the implemented methods marked as synchronized.class
TypedValueCombiner<V>
A Combiner that decodes each Value to type V before reducing, then encodes the result of typedReduce back to Value.class
WrappingIterator
A convenience class for implementing iterators that select, but do not modify, entries read from a source iterator. -
