Controller

abstract class Controller[Input, Output] extends CoreHandler with 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.

    Close the underlying connection. This is a "graceful" disconnect process, in that any action mid-completion will be given a chance to finish what they're doing before the connection actually closes. For example, for a service this will allow any requests being processed to complete.

    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

    createdMillis

    the timestamp of when the message was created, defaults to now if not specified

    postWrite

    called either when writing has completed or failed

    returns

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