All Known Subinterfaces:

ClientMessage, ICoreMessage
```
public interface Message
```
A Message is a routable instance that has a payload.
The payload (the "body") is opaque to the messaging system. A Message also has a fixed set of headers (required by the messaging system) and properties (defined by the users) that can be used by the messaging system to route the message (e.g. to ensure it matches a queue filter).
Message Properties

Message can contain properties specified by the users. It is possible to convert from some types to other types as specified by the following table:
```
 |        | boolean byte short int long float double String byte[]
 |----------------------------------------------------------------
 |boolean |    X                                      X
 |byte    |          X    X    X   X                  X
 |short   |               X    X   X                  X
 |int     |                    X   X                  X
 |long    |                        X                  X
 |float   |                              X     X      X
 |double  |                                    X      X
 |String  |    X     X    X    X   X     X     X      X
 |byte[]  |                                                   X
 |-----------------------------------------------------------------
 
```
If conversion is not allowed (for example calling getFloatProperty on a property set a boolean), a ActiveMQPropertyConversionException will be thrown. User cases that will be covered by Message Receiving a buffer: Message encode = new CoreMessage(); // or any other implementation encode.receiveBuffer(buffer); Sending to a buffer: Message encode; size = encode.getEncodeSize(); encode.encodeDirectly(bufferOutput);

setAddress

This will set the address on CoreMessage. Note for AMQPMessages: in AMQPMessages this will not really change the address on the message. Instead it will add a property on extraProperties which only transverse internally at the broker. Whatever you change here it won't affect anything towards the received message. If you wish to change AMQPMessages address you will have to do it directly at the AMQP Message, however beware that AMQPMessages are not supposed to be changed at the broker, so only do it if you know what you are doing.

Parameters:

address -
