Class CachingFutureModel<T extends Serializable>

java.lang.Object

com.databasesandlife.util.wicket.CachingFutureModel<T>

Type Parameters:

T -

All Implemented Interfaces:

Serializable, org.apache.wicket.model.IDetachable, org.apache.wicket.model.IModel<T>, org.apache.wicket.util.io.IClusterable

public abstract class CachingFutureModel<T extends Serializable>
extends Object
implements org.apache.wicket.model.IModel<T>

Can be used simple as a cache of a Future, or also as a Wicket model.

Futures have the problem that they are not serializable. Wicket only needs to serialize things after they've been displayed, i.e. after the future has delivered its results.
