Class ContentEntry

Object

ContentEntry

Direct Known Subclasses:

MemoryEntry

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;
