    • handleTransactionBeforeCommitting

      void handleTransactionBeforeCommitting(ITransaction transaction, IStoreAccessor.CommitContext commitContext, org.eclipse.net4j.util.om.monitor.OMMonitor monitor) throws RuntimeException
      Provides a way to handle transactions that are to be committed to the backend store.
      Parameters:
      transaction - The transaction that is going to be committed.
      commitContext - The context of the commit operation that is to be executed against the backend store. The context can be used to introspect all aspects of the current commit operation. Note that you must call commitContext.modify() if you plan to alter the internal state of the commit context!
      monitor - A monitor that should be used by the implementor to avoid timeouts.
      Throws:
      IRepository.WriteAccessHandler.TransactionValidationException - to indicate that the commit operation must not be executed against the backend store because some semantic validation checks failed. The message should describe the validation failure and will be passed through to the client
      RuntimeException - to indicate that the commit operation must not be executed against the backend store. This exception will be visible at the client side!

      Parameters:
      transaction - The transaction that has been committed.
      commitContext - The context of the commit operation that was executed against the backend store. The context can be used to introspect all aspects of the current commit operation. Note that you must not alter the internal state of the commit context in any way!
