TransactionalCallable (jOOQ 3.12.4 API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface TransactionalCallable<T>
```
An FunctionalInterface that wraps transactional code.
Transactional code should not depend on any captured scope, but use the argument Configuration passed to the run(Configuration) method to derive its transaction context.
If transactional code needs to depend on captured scope ("context"), then ContextTransactionalCallable is a better fit.

- Method Summary
  
  All Methods Instance Methods Abstract Methods
  Modifier and Type Method Description
  
  T run(Configuration configuration)
  Run the transactional code.

- Method Detail
  - run
```
T run(Configuration configuration)
throws Throwable
```
    Run the transactional code.
    If this method completes normally, and this is not a nested transaction, then the transaction will be committed. If this method completes with an exception (any Throwable), then the transaction is rolled back to the beginning of this TransactionalCallable.
    
    Parameters:
    
    configuration - The Configuration in whose context the transaction is run.
    
    Returns:
    
    The outcome of the transaction.
    
    Throws:
    
    Throwable - Any exception that will cause a rollback of the code contained in this transaction. If this is a nested transaction, the rollback may be performed only to the state before executing this TransactionalCallable.
