Interface Summary

Interface	Description
IAsyncResultHandler<R,A,O,X extends KVO<O>>	Interface for chunk-at-a-time result processing for asynchronous index writes.
IIndexProcedure<T>	An arbitrary procedure run against a single index.
IKeyArrayIndexProcedure<T>	Interface for procedures that are mapped across one or more index partitions based on an array of keys.
IKeyRangeIndexProcedure<T>	Interface for procedures that are mapped across one or more index partitions based on a key range (fromKey, toKey).
IParallelizableIndexProcedure<T>	A marker interface for an IIndexProcedure whose operation may be safely applied in parallel to multiple index partitions.
IResultHandler<R,A>	An interface for handling results obtained when an IIndexProcedure is parallelized across either a local index or partitions of a scale-out index.
ISimpleIndexProcedure<T>	Interface for procedures that operation on a single index or index partition

Class Summary

Class	Description
AbstractIndexProcedure<T>	Base class has some utility methods.
AbstractKeyArrayIndexProcedure<T>	Abstract base class supports compact serialization and compression for remote IKeyArrayIndexProcedure execution (procedures may be executed on a local index, but they are only (de-)serialized when executed on a remote index).
AbstractKeyArrayIndexProcedure.ResultBitBuffer	A class useful for sending a logical boolean[] back from a remote procedure call.
AbstractKeyArrayIndexProcedure.ResultBitBufferCounter	Counts the #of true bits in the AbstractKeyArrayIndexProcedure.ResultBitBuffer(s).
AbstractKeyArrayIndexProcedure.ResultBitBufferHandler	Knows how to aggregate AbstractKeyArrayIndexProcedure.ResultBitBuffer objects.
AbstractKeyArrayIndexProcedure.ResultBuffer	A class useful for sending some kinds of data back from a remote procedure call (those readily expressed as a byte[][]).
AbstractKeyArrayIndexProcedure.ResultBufferHandler	Knows how to aggregate AbstractKeyArrayIndexProcedure.ResultBuffer objects.
AbstractKeyArrayIndexProcedureConstructor<T extends IKeyArrayIndexProcedure>	A factory for IKeyArrayIndexProcedures so that their data may be key range partitions and mapped against each relevant index partition.
AbstractKeyRangeIndexProcedure<T>
AbstractLocalSplitResultAggregator<R>	Aggregator base class collects the individual results in an internal ordered map and assembles the final result when it is requested from the individual results.
BatchContains	Batch existence test operation.
BatchContains.BatchContainsConstructor	Factory for BatchContains procedures.
BatchInsert	Batch insert operation.
BatchInsert.BatchInsertConstructor	Factory for BatchInsert procedures.
BatchLookup	Batch lookup operation.
BatchLookup.BatchLookupConstructor	Factory for BatchLookup procedures.
BatchPutIfAbsent	Batch conditional insert operation (putIfAbsent).
BatchPutIfAbsent.BatchPutIfAbsentConstructor	Factory for BatchPutIfAbsent procedures.
BatchRemove	Batch removal of one or more tuples, optionally returning their existing values, the #of tuples that were deleted, or a mask indicating which tuples were deleted (polymorphic return type).
BatchRemove.BatchRemoveConstructor	Factory for BatchRemove procedures.
BooleanORAggregator	Combines together boolean values using a logical OR.
IntegerAggregator	Aggregates the value of an Integer result, making the sum available as a Long integer (to help prevent overflow).
ListResultAggregator<R,A extends List<R>>	Aggregates result into a list of results.
LongAggregator	Aggregates the value of an Long result.
RangeCountProcedure	This procedure computes a range count on an index.
SplitValuePair<K extends Split,V>	A key/value pair where the key is a Split.
SplitValuePair.PairComparator<K extends Split,V>	Sorts SplitValuePairs.
TestAll	Aggregates test suites into increasing dependency order.
