Class ContentEntry

  • Direct Known Subclasses:

    public class ContentEntry
    extends Object
    An entry for a type or feature source provided by a DataStore.

    This class is only of concern to subclasses, client code should never see this class.

    Each entry maintains state on a per-transaction basis. The getState(Transaction) method is used to get at this state.

       ContentEntry entry = ...;
       Transaction tx1 = new Transaction();
       Transaction tx2 = new Transaction();
       ContentState s1 = entry.getState( tx1 );
       ContentState s2 = entry.getState( tx2 );
       s1 != s2;
