Class SessionQuotaManagingDataStore

java.lang.Object

org.wicketstuff.datastores.common.SessionQuotaManagingDataStore

All Implemented Interfaces:

org.apache.wicket.pageStore.IDataStore

public class SessionQuotaManagingDataStore
extends Object
implements org.apache.wicket.pageStore.IDataStore

An implementation of IDataStore that delegates the actual work to another IDataStore. The extra logic that this class provides is to manage the quota per client (http session). This way one client cannot add too much data in the real/delegate data store and eventually drop another client's data.
