public async void unprepare () throws Error

Clean up and release resources used by the aggregator.

This will disconnect the aggregator cleanly from any resources it or its persona stores are using. It is recommended to call this method before finalising the individual aggregator, but calling it is not required. If this method is not called then, for example, unsaved changes in backends may not be flushed.

Concurrent calls to this function from different threads will block until preparation has completed. However, concurrent calls to this function from a single thread might not, i.e. the first call will block but subsequent calls might return before the first one. (Though they will be safe in every other respect.)



if unpreparing the backend-specific services failed — this will be a backend-specific error
