Package org.apache.accumulo.core.iterators

Interface Summary

IteratorEnvironment
OptionDescriber	The OptionDescriber interface allows you to set up iterator properties interactively in the accumulo shell.
SortedKeyValueIterator<K extends WritableComparable<?>,V extends Writable>	An iterator that supports iterating over key and value pairs.
TypedValueCombiner.Encoder<V>	An interface for translating from byte[] to V and back.

Class Summary

AggregatingIterator	Deprecated. since 1.4, replaced by Combiner
ColumnFamilyCounter
Combiner	A SortedKeyValueIterator that combines the Values for different versions of a Key into a single Value.
Combiner.ValueIterator	A Java Iterator that iterates over the Values for a given Key from a source SortedKeyValueIterator.
DebugIterator
DevNull	An iterator that is useful testing...
FamilyIntersectingIterator	Deprecated. since 1.4, replaced by IndexedDocIterator
Filter	A SortedKeyValueIterator that filters entries from its source iterator.
FilteringIterator	Deprecated. since 1.4, replaced by Filter
FirstEntryInRowIterator
GrepIterator	Deprecated. since 1.4, replaced by GrepIterator
IntersectingIterator	Deprecated. since 1.4, replaced by IntersectingIterator
IteratorUtil
IteratorUtil.IterInfoComparator
LargeRowFilter	Deprecated. since 1.4, replaced by LargeRowFilter
LongCombiner	A TypedValueCombiner that translates each Value to a Long before reducing, then encodes the reduced Long back to a Value.
LongCombiner.FixedLenEncoder	An Encoder that uses an 8-byte encoding for Longs.
LongCombiner.StringEncoder	An Encoder that uses a String representation of Longs.
LongCombiner.VarLenEncoder	An Encoder that uses a variable-length encoding for Longs.
NoLabelIterator	Deprecated. since 1.4, replaced by ReqVisFilter
OptionDescriber.IteratorOptions
OrIterator	An iterator that handles "OR" query constructs on the server side.
OrIterator.TermSource
RegExIterator	Deprecated. since 1.4, replaced by RegExFilter
RowDeletingIterator	Deprecated. since 1.4, replaced by RowDeletingIterator
SkippingIterator
SortedKeyIterator
SortedMapIterator	A simple iterator over a Java SortedMap
TypedValueCombiner<V>	A Combiner that decodes each Value to type V before reducing, then encodes the result of typedReduce back to Value.
VersioningIterator	Deprecated. since 1.4, replaced by VersioningIterator
WholeRowIterator	Deprecated. since 1.4, replaced by WholeRowIterator
WrappingIterator	A convenience class for implementing iterators that select, but do not modify, entries read from a source iterator.
