    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")

case class Exchange(name: String) extends Product with Serializable

Describes an exchange which should already exist, an error will be thrown on use if it does not

It is recommended to use ChannelOwner.declareExchange or ChannelOwner.declareExchangePassive to create this as they ensures the exchange exists.

    Specifies routing and send parameters

    routingKey

    the exchange uses this to decide which queue(s) the message is to be added to

    mandatory

    a message with this flag will be returned by the exchange if it finds that no queues match the routingKey

    immediate

    a message with this flag will only be delivered if a matching queue has a ready consumer, if not it is returned

    deliveryMode

    defines whether a message should be persisted if the queue it is on is persisted
