Controller

abstract class Controller[Input, Output] extends InputController[Input, Output] with OutputController[Input, Output]

A Controller is a Connection handler that is designed to work with connections involving decoding raw bytes into input messages and encoding output messages into bytes.

Unlike a service, which pairs an input "request" message with an output "response" message, the controller make no such pairing. Thus a controller can be thought of as a duplex stream of messages.

  1. abstract def idleCheck(period: Duration): Unit

    Called periodically on every attached connection handler, this can be used for checking if an ongoing operation has timed out.

    Called periodically on every attached connection handler, this can be used for checking if an ongoing operation has timed out.

    Be aware that this is totally independant of a connection's idle timeout, which is only based on the last time there was any I/O.

    period

    the frequency at which this method is called. Currently this is hardcoded to WorkerManager.IdleCheckFrequency, but may become application dependent in the future.

    Push a message to be written

    Pushing a message does not necessarily mean it will be written, but rather that the message is queued to be written. Messages can be queue regardless of the state of the underlying connection, even if the connection is never reconnected. It is up to the caller to determine whether a message should be pushed based on connection state.

    item

    the message to push

    postWrite

    called either when writing has completed or failed

    returns

    true if the message was successfully enqueued, false if the queue is full

    This function is called to signal to the handler that it can resume writing data. It is called as part of the WriteEndPoint event loop write cycle, where previously this handler attempted to write data, but the buffers were filled up. This is called once the buffers are empty again and able to receive data. This handler should be in a state where it is paused on writing data until this handler is invoked.
