public abstract class AbstractStorageService extends net.shibboleth.utilities.java.support.component.AbstractIdentifiableInitializableComponent implements StorageService, StorageCapabilities
StorageService implementations.
The base class handles support for a background cleanup task, and handles calling of custom object serializers.
