Class DataMessage

source code


I am used to transport an operation that occured on a managed object or collection.

This class of message is transmitted between clients subscribed to a remote destination as well as between server nodes within a cluster. The payload of this message describes all of the relevant details of the operation. This information is used to replicate updates and detect conflicts.
