  Scala wrapper for interacting with AMQP, the aim is for convenient: - scala style usage - RPC calls - event hooks - reconnection strategies - message creation and extraction for common message types

  Overview

  Build connections with io.leonard.amqp.ConnectionHolder.builder

  Create a connection:

  val connection = ConnectionHolder.builder("amqps://guest:password@host:port")
    .eventHooks(EventHooks(eventListener))
    .reconnectionStrategy(ReconnectionStrategy.JavaClientFixedReconnectDelay(1 second))
    .build()

  Create a channel:

  val channel = connection.newChannel()

  Create an RPC server listening on queue "queue.name", expecting a String and echoing it back:

  def rpcHandler(request: Message): Future[Message] = request match {
    case Message.String(string) => Future(Message.String(string))
  }
  val queue = QueueDeclare(Some("queue.name"))
  val rpcServerCloser = channel.rpcServer(queue, AckOnHandled)(rpcHandler)

  Create an RPC client method which sends requests to the queue "queue.name" with a response timeout of 10 seconds :

  val rpcClient = RPCClient(channel)
  val rpcMethod = rpcClient.newMethod(Exchange.Default.route("queue.name"), 10 second)

  Create a consumer on "queue.name" printing out strings sent to it:

  def consumer(request: Message): Unit = request match {
    case Message.String(string) => println(string)
  }
  val queue = QueueDeclare(Some("queue.name"))
  channel.addConsumer(queue, consumer)

  Send a message to "queue.name":

  channel.send(Exchange.Default.route("queue.name"), Message.String("message")
