ClassDescriptionA SortedKeyValueIterator that combines the Values for different versions (timestamp) of a Key within a row into a single Value.A Java Iterator that iterates over the Values for a given Key from a source SortedKeyValueIterator.An iterator that is useful testing...A SortedKeyValueIterator that filters entries from its source iterator.Utility class for Iterators.Even though this type is not in a public API package, its used by methods in the public API.A TypedValueCombiner that translates each Value to a Long before reducing, then encodes the reduced Long back to a Value.An Encoder that uses an 8-byte encoding for Longs.An Encoder that uses a String representation of Longs.An Encoder that uses a variable-length encoding for Longs.The OptionDescriber interface allows you to set up iterator properties interactively in the accumulo shell.An iterator that provides a sorted-iteration of column qualifiers for a set of column families in a row.An optimized version of
Filter.An optimized version ofSkippingIterator.An optimized version ofWrappingIterator.Every call toSkippingIterator.next()andSkippingIterator.seek(Range, Collection, boolean)calls the parent's implementation and then calls the implementation'sSkippingIterator.consume().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.A SortedKeyValueIterator similar toServerFilterbut with the implemented methods marked as synchronized.A Combiner that decodes each Value to type V before reducing, then encodes the result of typedReduce back to Value.Exception used for TypedValueCombiner and it's Encoders decode() functionA convenience class for implementing iterators that select, but do not modify, entries read from a source iterator.This callback handles the state of yielding within an iteratorYieldingKeyValueIterator<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)
