Interface | Description |
---|---|
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.
|
YieldingKeyValueIterator<K extends org.apache.hadoop.io.WritableComparable<?>,V extends org.apache.hadoop.io.Writable> |
An iterator that supports yielding on a next or seek call (only used by SortedKeyValueIterators)
|
Class | Description |
---|---|
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...
|
Filter |
A SortedKeyValueIterator that filters entries from its source iterator.
|
FirstEntryInRowIterator | |
IteratorAdapter | |
IteratorUtil | |
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 provides a sorted-iteration of column qualifiers for a set of column families in
a row.
|
OrIterator.TermSource | |
ServerFilter |
An optimized version of
Filter . |
ServerSkippingIterator |
An optimized version of
SkippingIterator . |
ServerWrappingIterator |
An optimized version of
WrappingIterator . |
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().
|
SynchronizedServerFilter |
A SortedKeyValueIterator similar to
ServerFilter but
with the implemented methods marked as synchronized. |
TypedValueCombiner<V> |
A Combiner that decodes each Value to type V before reducing, then encodes the result of
typedReduce back to Value.
|
WrappingIterator |
A convenience class for implementing iterators that select, but do not modify, entries read from
a source iterator.
|
YieldCallback<K> |
This callback handles the state of yielding within an 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
