Interface EnumeratableStorageService

All Superinterfaces:

Component, IdentifiedComponent, StorageService

All Known Implementing Classes:

AbstractMapBackedStorageService

public interface EnumeratableStorageService
extends StorageService

An extended StorageService able to enumerate the keys in a context.

In principle, it is theoretically possible to implement this extension in a stateful manner, thus the use of Iterable. In practice, this is exceedingly unlikely to work given the locking requirements and risks of contention this would create.

Since:

5.0.0
