| IteratorEnvironment | |
| OptionDescriber |
The OptionDescriber interface allows you to set up iterator properties interactively in the accumulo shell.
|
| SortedKeyValueIterator<K extends org.apache.hadoop.io.WritableComparable<?>,V extends org.apache.hadoop.io.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 | Description |
|---|---|
| AggregatingIterator | Deprecated
since 1.4, replaced by
Combiner |
| ColumnFamilyCounter | |
| Combiner |
A SortedKeyValueIterator that combines the Values for different versions (timestamp) of a Key within a row 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.
|
| 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.
|
| OptionDescriber.IteratorOptions | |
| OrIterator |
An iterator that handles "OR" query constructs on the server side.
|
| OrIterator.TermSource | |
| RowDeletingIterator | Deprecated
since 1.4, replaced by
RowDeletingIterator |
| 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(). |
| SortedKeyIterator | |
| 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().
|
| 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.
|
| Enum | Description |
|---|---|
| IteratorUtil.IteratorScope |
Even though this type is not in a public API package, its used by methods in the public API.
|
| LongCombiner.Type |
| Exception | Description |
|---|---|
| IterationInterruptedException | |
| ValueFormatException |
Exception used for TypedValueCombiner and it's Encoders decode() function
