Method Detail

makeOperationsFromTuple

protected TupleOperations makeOperationsFromTuple(TarantoolTuple tuple)

Description copied from class: TarantoolSpace

Create a TupleOperations instance from the given tuple of type T

Specified by:

makeOperationsFromTuple in class TarantoolSpace<TarantoolTuple,TarantoolResult<TarantoolTuple>>

Parameters:

tuple - tuple of the specified type

Returns:

new TupleOperations instance

arrayTupleResultMapper

protected MessagePackValueMapper arrayTupleResultMapper()

Description copied from class: TarantoolSpace

MessagePack value mapper configured with an ArrayValue to tuple converter corresponding to the selected tuple type

Specified by:

arrayTupleResultMapper in class TarantoolSpace<TarantoolTuple,TarantoolResult<TarantoolTuple>>

Returns:

configured mapper with ArrayValue to T converter

toString

public String toString()

Overrides:

toString in class TarantoolSpace<TarantoolTuple,TarantoolResult<TarantoolTuple>>

cursor

public TarantoolCursor<TarantoolTuple> cursor(Conditions conditions,
                                              int batchSize)

Description copied from interface: TarantoolSpaceOperations

Cursor is an iterator-like object that is able to scroll through results of a query. Unlike a single cursor loads new tuples dynamically issuing requests to server.

Select will fetch tuples matching the specified query. Each request to server will fetch no more than 'batch size' tuples.

Parameters:

conditions - query with options

batchSize - size of a batch of single client request

Returns:

cursor that can iterate through all corresponding tuples

cursor

public TarantoolCursor<TarantoolTuple> cursor(Conditions conditions)

Description copied from interface: TarantoolSpaceOperations

Same as TarantoolSpaceOperations.cursor(Conditions, int) but uses the default batch size.

Parameters:

conditions - query with options

Returns:

cursor that can iterate through all corresponding tuples
