## Interface TransactionalTask<T>

-     public interface TransactionalTask<T>

  Contains the logic that is going to be executed within a transaction. In practice, the implementation will be an anonymous inner task.

  Unlike the `Runnable` and `Callable`, the `TransactionalTask` will run on the caller thread.
