Class RecordList

  • public class RecordList
extends Object
    This class manages instances of the classes derived from AbstractRecord in the form of an ordered doubly-linked list. The ordering and insertion criteria are not particularly standard - see the comment on 'insert' for the actual algorithm used in insertion. The algorithm assumes that one or more different record type instances (LockRecords, RecoveryRecords, etc.) will be inserted into the list at different times. Each such record contains specific information managing certain properties of any particular object. As execution progresses newly created records may need to be merged with, replace entirely, or be added to existing records that relate to an object. Note, the methods of this class do not need to be synchronized because instances of this class are only used from within synchronized classes. Applications should not use this class.
