Uses of WrappingIterator in org.apache.accumulo.core.iterators
Subclasses of WrappingIterator in org.apache.accumulo.core.iterators Modifier and Type Class Description class
Combiner
A SortedKeyValueIterator that combines the Values for different versions (timestamp) of a Key within a row into a single Value.class
DebugIterator
class
Filter

LongCombiner
A TypedValueCombiner that translates each Value to a Long before reducing, then encodes the reduced Long back to a Value.class
SkippingIterator
Every call toSkippingIterator.next()
andSkippingIterator.seek(Range, Collection, boolean)
calls the parent's implementation and then calls the implementation'sSkippingIterator.consume()
