Uses of WrappingIterator in org.apache.accumulo.core.iterators
 

Subclasses of WrappingIterator in org.apache.accumulo.core.iterators
 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
          A SortedKeyValueIterator that filters entries from its source iterator.
 class FirstEntryInRowIterator
           
 class 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 to SkippingIterator.next() and SkippingIterator.seek(Range, Collection, boolean) calls the parent's implementation and then calls the implementation's SkippingIterator.consume().
 class SortedKeyIterator
           
 class TypedValueCombiner<V>
          A Combiner that decodes each Value to type V before reducing, then encodes the result of typedReduce back to Value.

          A Filter that matches entries based on Java regular expressions.
 class ReqVisFilter
          A Filter that matches entries with a non-empty ColumnVisibility.
 class RowFilter
          This iterator makes it easy to select rows that meet a given criteria.
 class SummingArrayCombiner
          A Combiner that interprets Values as arrays of Longs and returns an array of element-wise sums.
 class SummingCombiner
          A Combiner that interprets Values as Longs and returns their sum.
 class TimestampFilter
          A Filter that matches entries whose timestamps fall within a range.
 class TransformingIterator
