Abstract Record Class This class provides an abstract template that defines the interface that the atomic action system uses to notify objects that various state transitions have occurred as the 2PC protocol executes. Record types derived from this class manage certain properties of objects such as recovery information, concurrency control information etc, and all must redifine the operations defined here as abstract to take appropriate action. Many functions are declared pure virtual to force a definition to occur in any derived class. These are currently all functions dealing with atomic action coordination as well as the following list management functions: typeIs: returns the record type of the instance. This is one of the values of the enumerated type Record_type value: Some arbitrary value associated with the record instance merge: Used when two records need to merge togethor. Currently this is only used by CadaverRecords to merge information from PersistenceRecords shouldAdd: returns TRUE is the record should be added to the list FALSE if it should be discarded shouldMerge: returns TRUE is the two records should be merged into a single record, FALSE if it should be discarded shouldReplace: returns TRUE if the record should replace an existing one, FALSE otherwise. @author Mark Little (mark@arjuna.com) @version $Id: AbstractRecord.java 2342 2006-03-30 13:06:17Z $ @since 1.0.
