A provider for TransactionListener instances. 

In order to facilitate the lifecycle management of
TransactionListener instances that are provided to a jOOQ Configuration, clients can implement this API. To jOOQ, it is thus irrelevant, if transaction listeners are stateful or stateless, local to an execution, or global to an application.
