-** QPid-compatible JMS BytesMessage, StreamMessage, and MapMessage codecs
-
-The [code RabbitMQ.Client.Content] namespace contains classes and
-interfaces that implement QPid-compatible JMS BytesMessage,
-StreamMessage and MapMessage encoders and decoders.
-
-For example, to construct (and send) a MapMessage:
-
-@code java
-  IModel channel = ...;
-
-  IMapMessageBuilder b = new MapMessageBuilder(channel);
-  b.Headers["header1"] = "[email protected]";
-  b.Body["field1"] = 123.45;
-  b.Body["field2"] = new byte[] { 1, 2, 3 };
-
-  channel.BasicPublish(exchange, routingKey,
-                       (IBasicProperties)  b.GetContentHeader(),
-                       b.GetContentBody());
-
-A StreamMessage is similar (and BytesMessages are so similar to
-StreamMessages that I shan't demonstrate them here):
-
-@code java
-  IStreamMessageBuilder b = new StreamMessageBuilder(channel);
-  b.Headers["header1"] = "[email protected]";
-  b.WriteDouble(123.45);
-  b.WriteBytes(new byte[] { 1, 2, 3 });
-
-Given a received message in the form of an [code IBasicProperties]
-header and a [code byte[]] body, reading the message as a MapMessage
-is done with [code IMapMessageReader]:
-
-@code java
-  IBasicProperties props = ...;
-  byte[] receivedBody = ...;
-  IMapMessageReader r = new MapMessageReader(props, receivedBody);
-  Console.Out.WriteLine("Header1: {0}", r.Headers["header1"]);
-  Console.Out.WriteLine("Field1: {0}", r.Body["field1"]);
-  Console.Out.WriteLine("Field2: {0}", r.Body["field2"]);
-
-StreamMessages (and BytesMessages) are similar:
-
-@code java
-  IStreamMessageReader r = new StreamMessageReader(props, receivedBody);
-  Console.Out.WriteLine("Header1: {0}", r.Headers["header1"]);
-  Console.Out.WriteLine("First value: {0}", r.ReadDouble());
-  Console.Out.WriteLine("Second value: {0}", r.ReadBytes());
