Transaction

@Transaction annotation gives a transactional context around a method.

• begin transaction
• execute()
• commit
• rollback on exception

class AUseCase
{
    /**
     * @Transaction
     */
    public function execute(UseCaseRequest $useCaseRequest)
    {
        // do things
        
        return $useCaseResponse;
    }
}

Exceptions occurring during the transaction can be mapped so that the method returns another exception instead

class AUseCase
{
    /**
     * @Transaction(exceptions={
     *     "SomeInfrastructureException"="SomeDomainException"
     * })
     */
    public function execute(UseCaseRequest $useCaseRequest)
    {
        // do things
        
        return $useCaseResponse;
    }
}
