ObjectMessage (TIBCO Enterprise Message Service)

All Superinterfaces:

Message
```
public interface ObjectMessage
extends Message
```
An ObjectMessage object is used to send a message that contains a serializable object in the Java programming language ("Java object"). It inherits from the Message interface and adds a body containing a single reference to an object. Only Serializable Java objects can be used.
If a collection of Java objects must be sent, one of the Collection classes provided since JDK 1.2 can be used.
When a client receives an ObjectMessage, it is in read-only mode. If a client attempts to write to the message at this point, a MessageNotWriteableException is thrown. If clearBody is called, the message can now be both read from and written to.

Since:

JMS 1.0

- Method Detail
  - setObject
```
void setObject(java.io.Serializable object)
        throws JMSException
```
    Sets the serializable object containing this message's data. It is important to note that an ObjectMessage contains a snapshot of the object at the time setObject() is called; subsequent modifications of the object will have no effect on the ObjectMessage body.
    
    Parameters:
    
    object - the message's data
    
    Throws:
    
    JMSException - if the Jakarta Messaging provider fails to set the object due to some internal error.
    
    MessageFormatException - if object serialization fails.
    
    MessageNotWriteableException - if the message is in read-only mode.
  - getObject
```
java.io.Serializable getObject()
                        throws JMSException
```
    Gets the serializable object containing this message's data. The default value is null.
    
    Returns:
    
    the serializable object containing this message's data
    
    Throws:
    
    JMSException - if the Jakarta Messaging provider fails to get the object due to some internal error.
    
    MessageFormatException - if object deserialization fails.
