    • syncEntities

      public static final void syncEntities(de.xima.cmn.dao.interfaces.IEntity<Long> entity, de.xima.cmn.dao.interfaces.IEntity<Long> persisted)

    • withTransaction

      public static <T, E extends Throwable> T withTransaction(IEntityContext ec, ITypedThrowingSupplier<T,E> action) throws E
      Invokes the given action within the context of a transaction. Starts a new transaction if none is active, then invokes the given action. When the action completes successfully, the transaction is committed. If an exception is thrown, the transaction is rolled back, and the exception is rethrown.

      E - Type of the exception that can be thrown by the action.
      Parameters:
      ec - Entity context for database operations.
      action - Action to be executed within the transaction.
