Interface WriteListener

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface WriteListener

Listener notified when the network layer has finished writing a message body.

This is primarily useful when publishing with an off-heap ByteBuffer: the callback tells the caller when the buffer is no longer in use and can be safely released.

This only applies when using Netty as the IO layer and is unnecessary when using the blocking IO layer.

Threading: the callback may be invoked on the Netty event loop thread. Implementations must not perform blocking operations.

This API is experimental and is susceptible to change at any time.

Since:

5.30.0
