org.nasutekds.server.replication.plugin.EntryHistorical
This class is used to store historical information that is used to resolve modify conflicts It is assumed that the common case is not to have conflict and therefore is optimized (in order of importance) for : 1- detecting potential conflict 2- fast update of historical information for non-conflicting change 3- fast and efficient purge 4- compact 5- solve conflict. This should also be as fast as possible but not at the cost of any of the other previous objectives One Historical object is created for each entry in the entry cache each Historical Object contains a list of attribute historical information


    List<AttributeValue> duplicateValues = new LinkedList<AttributeValue>();
    entry.addAttribute(builder.toAttribute(), duplicateValues);


    // load historical from the entry
    EntryHistorical hist = EntryHistorical.newInstanceFromEntry(entry);


    /*
     * simulate a delete of the description attribute value "value1"
     * done at time t3
     */
