Package org.apache.pekko.remote.transport

Interface AssociationHandle

  • All Known Implementing Classes:
    AbstractTransportAdapterHandle, TestAssociationHandle
    public interface AssociationHandle
    Deprecated.
    Classic remoting is deprecated, use Artery. Since Akka 2.6.0.
    An SPI layer for abstracting over logical links (associations) created by a pekko.remote.transport.Transport. Handles are responsible for providing an API for sending and receiving from the underlying channel.

    To register a listener for processing incoming payload data, the listener must be registered by completing the Promise returned by pekko.remote.transport.AssociationHandle#readHandlerPromise. Incoming data is not processed until this registration takes place.

    • Method Detail

      • localAddress

        Address localAddress()
        Deprecated.
        Address of the local endpoint.

        Returns:
        Address of the local endpoint.

      • remoteAddress

        Address remoteAddress()
        Deprecated.
        Address of the remote endpoint.

        Returns:
        Address of the remote endpoint.

      • readHandlerPromise

        scala.concurrent.Promise<AssociationHandle.HandleEventListener> readHandlerPromise()
        Deprecated.
        The Promise returned by this call must be completed with an pekko.remote.transport.AssociationHandle.HandleEventListener to register a listener responsible for handling incoming payload. Until the listener is not registered the transport SHOULD buffer incoming messages.

        Returns:
        Promise that must be completed with the listener responsible for handling incoming data.

      • write

        boolean write​(ByteString payload)
        Deprecated.
        Asynchronously sends the specified payload to the remote endpoint. This method MUST be thread-safe as it might be called from different threads. This method MUST NOT block.

        Writes guarantee ordering of messages, but not their reception. The call to write returns with a Boolean indicating if the channel was ready for writes or not. A return value of false indicates that the channel is not yet ready for delivery (e.g.: the write buffer is full) and the sender needs to wait until the channel becomes ready again. Returning false also means that the current write was dropped (this MUST be guaranteed to ensure duplication-free delivery).

        Parameters:
        payload - The payload to be delivered to the remote endpoint.
        Returns:
        Boolean indicating the availability of the association for subsequent writes.

      • disassociate

        void disassociate()
        Deprecated.
        Use method that states reasons to make sure disassociation reasons are logged. Since Akka 2.5.3.
        Closes the underlying transport link, if needed. Some transports might not need an explicit teardown (UDP) and some transports may not support it (hardware connections). Remote endpoint of the channel or connection MAY be notified, but this is not guaranteed. The Transport that provides the handle MUST guarantee that disassociate() could be called arbitrarily many times.

      • disassociate

        void disassociate​(java.lang.String reason,
                  LoggingAdapter log)
        Deprecated.
        Closes the underlying transport link, if needed. Some transports might not need an explicit teardown (UDP) and some transports may not support it (hardware connections). Remote endpoint of the channel or connection MAY be notified, but this is not guaranteed. The Transport that provides the handle MUST guarantee that disassociate() could be called arbitrarily many times.
