Interface TextMessage

All Superinterfaces:

Message

All Known Subinterfaces:

JMQXMLMessage

public interface TextMessage

extends Message

A TextMessage object is used to send a message containing a java.lang.String. It inherits from the Message interface and adds a text message body.

The inclusion of this message type is based on the presumption that XML will likely become a popular mechanism for representing content of all kinds, including the content of JMS messages.

When a client receives a TextMessage, 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.
