Class MicroSessionCacheService

java.lang.Object
overit.geocall.rs.MicroSessionCacheService
public class MicroSessionCacheService extends Object
MicroSessionCacheService is a class that provides a cache for MicroSession objects. It uses an ExpiringMap to store the MicroSession objects with an expiration time. The cache allows retrieval, insertion, and removal of MicroSessions.

MicroSessionCacheService is a singleton class, meaning there is only one instance of it throughout the application. It can be accessed using the getInstance() method. The MicroSessionCacheService instance holds the ExpiringMap cache and a Clock object to manage expiration logic.

Expiration of MicroSessions is handled through the ExpiringMap. It periodically removes expired MicroSessions using a background cleaning process executed by a scheduled executor service.

Usage: 


     // Retrieve the MicroSessionCacheService instance
     MicroSessionCacheService sessionCache = MicroSessionCacheService.getInstance();

     // Get a MicroSession from the cache
     MicroSession session = sessionCache.get("sessionId");

     // Put a MicroSession into the cache
     sessionCache.put(session);

     // Remove a MicroSession from the cache
     sessionCache.remove(session);
