io.lettuce.core.output.CommandOutput<K,V,List<Value<Boolean>>>

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

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

Type Parameters:

K - Key type.

V - Value type.

All Implemented Interfaces:

StreamingOutput<Value<Boolean>>

public class CuckooInsertBooleanValueListOutput<K,V>
extends ErrorTolerantBooleanValueListOutput<K,V>

List of Value-wrapped boolean output for the reactive CF.INSERTNX command.

Extends ErrorTolerantBooleanValueListOutput to add a 3-state mapping for the per-item integer response:

• 1 → Value.just(Boolean.TRUE) – item was added
• 0 → Value.just(Boolean.FALSE) – item already exists
• negative (e.g. -1) → Value.empty() – filter is full

The base class maps any non-1 integer to Value.just(false), which is correct for BF and CF.INSERT. CF.INSERTNX additionally returns 0 for "already exists", so this subclass overrides set(long) to distinguish 0 (Value.just(false)) from negative (Value.empty()).

public void set(long integer)

Description copied from class: CommandOutput

Update the command output with a 64-bit signed integer. Concrete CommandOutput implementations must override this method to decode number (integer) response values.

Overrides:

set in class ErrorTolerantBooleanValueListOutput<K,V>

Parameters:

integer - The command output.
