Interface PersistableCache<IdType,ObjectType>

Type Parameters:

IdType - the type of the values by which the cached objects can be identified

ObjectType - the type of the objects to be maintained in this cache

All Superinterfaces:

Cache<IdType,ObjectType>

All Known Implementing Classes:

public interface PersistableCache<IdType,ObjectType>
extends Cache<IdType,ObjectType>

A generic interface for data structures that can be used as a persisted cache for objects of a specific type. Implementations of this interface may employ their particular policies for cache replacement and for cache invalidation.

Method Details

save

void save()

Saves the current state of the cache to persistent storage. Implementations may choose different mechanisms for persistence, such as writing to a file or a database. This method should ensure that all cached data is synchronized with persistent storage. Depending on the implementation, synchronization may be automatic or explicitly controlled.

load

void load()

Loads the cache state from persistent storage. If persistent data exists, it should be restored into the cache. Implementations should handle cases where no prior state exists gracefully.
