Method Detail

eval

CompletableFuture<List<?>> eval(String expression)
                         throws TarantoolClientException

Execute a Lua expression in the Tarantool instance. If a result is expected, the expression must start with keyword return. The value mapper specified in the client configuration will be used for converting the result values from MessagePack entities to objects.

Parameters:

expression - lua expression, must not be null or empty

Returns:

some result

Throws:

TarantoolClientException - if the client is not connected

eval

CompletableFuture<List<?>> eval(String expression,
                                List<?> arguments)
                         throws TarantoolClientException

Execute a Lua expression in the Tarantool instance. If a result is expected, the expression must start with keyword return. The value mapper specified in the client configuration will be used for converting the result values from MessagePack entities to objects.

Parameters:

expression - lua expression, must not be null or empty

arguments - the list of function arguments. The object mapper specified in the client configuration will be used for arguments conversion to MessagePack entities

Returns:

some result

Throws:

TarantoolClientException - if the client is not connected

eval

CompletableFuture<List<?>> eval(String expression,
                                MessagePackValueMapper resultMapper)
                         throws TarantoolClientException

Execute a Lua expression in the Tarantool instance. If a result is expected, the expression must start with keyword return.

Parameters:

expression - lua expression, must not be null or empty

resultMapper - mapper for result value MessagePack entity-to-object conversion

Returns:

some result

Throws:

TarantoolClientException - if the client is not connected

eval

CompletableFuture<List<?>> eval(String expression,
                                List<?> arguments,
                                MessagePackValueMapper resultMapper)
                         throws TarantoolClientException

Execute a Lua expression in the Tarantool instance. If a result is expected, the expression must start with keyword return.

Parameters:

expression - lua expression, must not be null or empty

arguments - the list of function arguments. The object mapper specified in the client configuration will be used for arguments conversion to MessagePack entities

resultMapper - mapper for result value MessagePack entity-to-object conversion

Returns:

some result

Throws:

TarantoolClientException - if the client is not connected

eval

CompletableFuture<List<?>> eval(String expression,
                                List<?> arguments,
                                MessagePackObjectMapper argumentsMapper,
                                MessagePackValueMapper resultMapper)
                         throws TarantoolClientException

Execute a Lua expression in the Tarantool instance. If a result is expected, the expression must start with keyword return.

Parameters:

expression - lua expression, must not be null or empty

arguments - the list of function arguments

resultMapper - mapper for result value MessagePack entity-to-object conversion

Returns:

some result
