tag
Type: String
The tag property of the JadeGenericMessage class contains a string value that is stored with the message object. Unlike other properties, the value of the tag property is not used by JADE and is available for you to use for any purpose in your application.
Although the tag property is a property in the JadeGenericMessage object, it is not considered part of the message. Consequently it is not part of the data that is put in the queue and is not available for retrieval.
By default, the tag property is set to a null string ("").
