Class StoreAccessorBase

Method Details

• getStore

  public Store getStore()

  Description copied from interface: IStoreAccessor

  Returns the store this accessor is associated with.

  Specified by:

  getStore in interface IStoreAccessor

• isReader

  public boolean isReader()

  Description copied from interface: IStoreAccessor

  Returns true if this accessor has been configured for read-only access to the back-end, false otherwise.

  Specified by:

  isReader in interface IStoreAccessor

• getSession

  public InternalSession getSession()

  Description copied from interface: IStoreAccessor

  Returns the session this accessor is associated with.

  Specified by:

  getSession in interface IStoreAccessor

  3.0

• getTransaction

  public ITransaction getTransaction()

  Description copied from interface: IStoreAccessor

  Returns the transaction this accessor is associated with if IStoreAccessor.isReader() returns false, null otherwise.

  Specified by:

  getTransaction in interface IStoreAccessor

• release

  public void release()

  Specified by:

  release in interface IStoreAccessor

• write

  public final void write(InternalCommitContext context, org.eclipse.net4j.util.om.monitor.OMMonitor monitor)

  Description copied from interface: IStoreAccessor

  Called before committing. An instance of this accessor represents an instance of a back-end transaction. Could be called multiple times before commit it called. IStoreAccessor.commit(OMMonitor) or IStoreAccessor.rollback() will be called after any numbers of IStoreAccessor.write(InternalCommitContext, OMMonitor).

  Note: IStoreAccessor.write(InternalCommitContext, OMMonitor) and IStoreAccessor.commit(OMMonitor) could be called from different threads.

  Specified by:

  write in interface IStoreAccessor

  Since:

  3.0

• doWrite

  protected abstract void doWrite(InternalCommitContext context, org.eclipse.net4j.util.om.monitor.OMMonitor monitor)

• commit

  public final void commit(org.eclipse.net4j.util.om.monitor.OMMonitor monitor)

  Description copied from interface: IStoreAccessor

  Flushes to the back-end and makes available the data for others.

  Note: IStoreAccessor.write(InternalCommitContext, OMMonitor) and IStoreAccessor.commit(OMMonitor) could be called from different threads.

  Note: Implementors should detect if dirty write occurred. In this case it should throw an exception.

   if (revision.getVersion() != revisionDelta.getOriginVersion())
   {
     throw new ConcurrentModificationException("Trying to update object " + revisionDelta.getID()
         + " that was already modified");
   }

• rollback

  public final void rollback()

  Description copied from interface: IStoreAccessor

  Note: IStoreAccessor.write(InternalCommitContext, OMMonitor) and IStoreAccessor.rollback() could be called from different threads.

  Specified by:

  rollback in interface IStoreAccessor

• doRollback

  protected abstract void doRollback(IStoreAccessor.CommitContext commitContext)

• readResourceID

  public CDOID readResourceID(CDOID folderID, String name, CDOBranchPoint branchPoint)

  Description copied from interface: IStoreAccessor

  Returns the CDOID of the resource node with the given folderID and name if a resource with this folderID and name exists in the store, null otherwise.

  Specified by:

  readResourceID in interface IStoreAccessor

• loadCommitData

  public CDOCommitData loadCommitData(long timeStamp)

• addIDMappings

  public void addIDMappings(InternalCommitContext commitContext, org.eclipse.net4j.util.om.monitor.OMMonitor monitor)

  Add ID mappings for all new objects of a transaction to the commit context. The implementor must, for each new object of the commit context, determine a permanent CDOID and make it known to the context by calling InternalCommitContext.addIDMapping(CDOID, CDOID).

  Since:

  3.0

• getNewID

  public CDOID getNewID(CDORevision revision)

  Specified by:

  getNewID in interface IStoreAccessor.NewIDSupport

• doPassivate

  protected void doPassivate() throws Exception

  Throws:

  Exception

• doUnpassivate

  protected void doUnpassivate() throws Exception

  Throws:

  Exception
