Description Eike Stepper

2010-10-10 09:26:41 EDT

What used to be called the offline mode in CDO is actually way more than that. It's more like Git repository cloning with background replication. Very powerful, but sometimes not desirable because:

- Setup is complex (may be fixed in the future)
- Consumes resources even if the full power of cloned repositories are not needed (no offline history, no offline branching, no multiple offline clients, etc)

Often the requirements are much simpler:

- Work offline on a snapshot (no history, no branches)
- Update the snapshot occasionally
- Commit changes of the snapshot to the remote repository occasionally

Initial Design:

public final class CDOWorkspaceUtil
{
  public static CDOWorkspace checkout(IStore local, CDOSessionConfigurationFactory remote, String branchPath, long timeStamp);
  public static CDOWorkspace open(IStore local, CDOSessionConfigurationFactory remote);
}

public interface CDOWorkspace extends Closeable
{
  public IRepository getLocalRepository();
  public CDOView openView();
  public CDOView openView(ResourceSet resourceSet);
  public CDOTransaction openTransaction();
  public CDOTransaction openTransaction(ResourceSet resourceSet);
  public CDOTransaction update(CDOMerger merger);
  public CDOTransaction update(CDOMerger merger, String branchPath);
  public CDOTransaction update(CDOMerger merger, String branchPath, long timeStamp);
  public void revert();
  public void replace(String branchPath, long timeStamp);
  public void commit(String comment);
}
