Examples of org.jboss.cache.Modification

org.jboss.cache.Modification
Represents a modification in the cache. Contains the nature of the modification (e.g. PUT, REMOVE), the fqn of the node, the new value and the previous value. A list of modifications will be sent to all nodes in a cluster when a transaction has been committed (PREPARE phase). A Modification is also used to roll back changes, e.g. since we know the previous value, we can reconstruct the previous state by applying the changes in a modification listin reverse order. @author Bela Ban Apr 12, 2003 @version $Revision: 6776 $
