ContextTransactionalCallable (jOOQ 3.13.1 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 ContextTransactionalCallable<T>
```
An FunctionalInterface that wraps transactional code.
This callable may depend on captured scope ("context") in order to discover a contextual Configuration to be used to create new SQL statements. Clients are responsible to implement such context state in appropriate ConnectionProvider and TransactionProvider implementations.
An out-of-the-box implementation for a fitting TransactionProvider is available through ThreadLocalTransactionProvider.

- Method Detail
  - run
```
T run()
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 ContextTransactionalCallable.
    
    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 ContextTransactionalCallable.
