Examples of org.activemq.message.ActiveMQTextMessage

org.activemq.message.ActiveMQTextMessage
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.

This message type can be used to transport text-based messages, including those with XML content.

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. @see javax.jms.Session#createTextMessage() @see javax.jms.Session#createTextMessage(String) @see javax.jms.BytesMessage @see javax.jms.MapMessage @see javax.jms.Message @see javax.jms.ObjectMessage @see javax.jms.StreamMessage @see java.lang.String
