io.lettuce.core.output

Class CuckooInsertBooleanListOutput<K,V>

java.lang.Object

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

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

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

Type Parameters:

K - Key type.

V - Value type.

All Implemented Interfaces:

StreamingOutput<Boolean>

public class CuckooInsertBooleanListOutput<K,V>
extends ErrorTolerantBooleanListOutput<K,V>

List of boolean output for the CF.INSERTNX command.

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

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

The base class maps any non-1 integer to false, which is correct for BF and CF.INSERT (where -1 simply means "not added"). CF.INSERTNX additionally returns 0 for "already exists", so this subclass overrides set(long) to distinguish 0 (false) from negative (null).

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 ErrorTolerantBooleanListOutput<K,V>

Parameters:

integer - The command output.
