class MediatorState extends NamedLogging with FlagCloseable
Provides state management for messages received by the mediator.
Non-finalized response aggregations are kept in memory, such that in case of the node shutting down,
they are lost but the participants waiting for a transaction result will simply timeout.
The finalized response aggregations are stored in the provided FinalizedResponseStore.
It is expected that fetchPendingRequestIdsBefore operation is not called concurrently with operations
to modify the pending requests.

funless a shutdown has been initiated. The shutdown will only begin afterfcompletes, but other tasks may execute concurrently withf, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.- f

- returns
scala.None$ if a shutdown has been initiated. Otherwise the result of the task.
