Class ValueDoubleMapOutput<K,V>

java.lang.Object

io.lettuce.core.output.CommandOutput<K,V,Map<V,Double>>

io.lettuce.core.output.ValueDoubleMapOutput<K,V>

Type Parameters:

K - Key type.

V - Value type.

public class ValueDoubleMapOutput<K,V>
extends CommandOutput<K,V,Map<V,Double>>

Map of values and Doubles output. This output processes Redis responses into a map where keys are of type V (values from the codec) and values are of type Double.

This is particularly useful for commands that return elements with scores, such as VSIM with WITHSCORES option.

Constructor Detail

ValueDoubleMapOutput

public ValueDoubleMapOutput(RedisCodec<K,V> codec)

Initialize a new ValueDoubleMapOutput.

Parameters:

codec - Codec used to decode keys and values, must not be null.

Method Detail

set

public void set(ByteBuffer bytes)

Description copied from class: CommandOutput

Update the command output with a sequence of bytes, or null. Concrete CommandOutput implementations must override this method to decode bulk/bytes response values.

Overrides:

set in class CommandOutput<K,V,Map<V,Double>>

Parameters:

bytes - The command output, or null.

set

public void set(double number)

Description copied from class: CommandOutput

Update the command output with a floating-point number. Concrete CommandOutput implementations must override this method to decode double response values.

Overrides:

set in class CommandOutput<K,V,Map<V,Double>>

Parameters:

number - The command output.

multi

public void multi(int count)

Description copied from class: CommandOutput

Mark the beginning of a multi sequence (array).

Overrides:

multi in class CommandOutput<K,V,Map<V,Double>>

Parameters:

count - expected number of elements in this multi sequence.
