org.hornetq.api.core.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 {@code getFloatProperty} on a property set a{@code boolean}), a {@link PropertyConversionException} will be thrown. @author Tim Fox @author ClebertSuconic @version $Revision: 3341 $ $Id: Message.java 3341 2007-11-19 14:34:57Z timfox $
