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 StorageDataFileDissolvingEvaluator

Function type that evaluates if a storage file needs to be dissolved and its remaining data content be transferred to a new file.

Note that any implementation of this type must be safe enough to never throw an exception as this would doom the storage thread that executes it. Catching any exception would not prevent the problem for the channel thread as the function has to work in order for the channel to work properly. It is therefore strongly suggested that implementations only use "exception free" logic (like simple arithmetic) or handle any possible exception internally.
