Method Detail

• attachingObject

  public void attachingObject​(CDOTransaction transaction,
                              CDOObject object)

  Description copied from interface: CDOTransactionHandler1
  Called by a CDOTransaction before an object is added. The implementor of this method is allowed to throw an unchecked exception that will propagate up to the operation that is about to add the object (thereby preventing the operation from successful completion).

  Note: Implementors must not start threads which access the view and wait for their completion since deadlocks can result. The following example causes a deadlock:
  

   getDisplay().syncExec(new Runnable()
   {
     public void run()
     {
       try
       {
         cdoObject.getName();
       }
       catch (Exception ignore)
       {
       }
     }
   });
   

  If you need to synchronously execute threads which access the view you should use CDOAsyncTransactionHandler.

• modifyingObject

  public void modifyingObject​(CDOTransaction transaction,
                              CDOObject object,
                              CDOFeatureDelta featureDelta)

  Description copied from interface: CDOTransactionHandler1
  Called by a CDOTransaction before an object is modified. The implementor of this method is allowed to throw an unchecked exception that will propagate up to the operation that is about to modify the object (thereby preventing the operation from completing successfully).

  Note: Implementors must not start threads which access the view and wait for their completion since deadlocks can result. The following example causes a deadlock:
  

   getDisplay().syncExec(new Runnable()
   {
     public void run()
     {
       try
       {
         cdoObject.getName();
       }
       catch (Exception ignore)
       {
       }
     }
   });
   

  If you need to synchronously execute threads which access the view you should use CDOAsyncTransactionHandler.

• detachingObject

  public void detachingObject​(CDOTransaction transaction,
                              CDOObject object)

  Description copied from interface: CDOTransactionHandler1
  Called by a CDOTransaction before an object is detached. The implementor of this method is allowed to throw an unchecked exception that will propagate up to the operation that is about to remove the object (thereby preventing the operation from completing successfully).

  Note: Implementors must not start threads which access the view and wait for their completion since deadlocks can result. The following example causes a deadlock:
  

   getDisplay().syncExec(new Runnable()
   {
     public void run()
     {
       try
       {
         cdoObject.getName();
       }
       catch (Exception ignore)
       {
       }
     }
   });
   

  If you need to synchronously execute threads which access the view you should use CDOAsyncTransactionHandler.

• committingTransaction

  public void committingTransaction​(CDOTransaction transaction,
                                    CDOCommitContext commitContext)

  Description copied from interface: CDOTransactionHandler2
  Called by a CDOTransaction before it is being committed. The implementor of this method is allowed to throw an unchecked exception that will propagate up to the operation that is about to commit the transaction (thereby preventing the operation from completing successfully). The implementor of this method is allowed to apply changes to the object graph managed by the transaction.

• committedTransaction

  public void committedTransaction​(CDOTransaction transaction,
                                   CDOCommitContext commitContext)

  Description copied from interface: CDOTransactionHandler2
  Called by a CDOTransaction after it is being committed. The implementor of this method is not allowed to throw an unchecked exception.

  If you're interested in the results of the commit operation consider to implement CDOTransactionHandler3.committedTransaction().

• rolledBackTransaction

  public void rolledBackTransaction​(CDOTransaction transaction)

  Description copied from interface: CDOTransactionHandler2
  Called by a CDOTransaction after it is rolled back. If the implementor of this method throws an exception it will be logged as an error and subsequent handlers will be further called.
