  org.wings.Resource
      org.wings.resource.DynamicResource

All Implemented Interfaces:

Serializable, Renderable, URLResource

Direct Known Subclasses:

ReloadResource, UpdateResource

public abstract class DynamicResource
extends Resource

Dynamic Resources are web resources representing rendered components and are individually loaded by Browsers as different 'files'. Dynamic Resources include therefore frames, cascading stylesheets or script files. The externalizer gives them a uniqe name. The resources may change in the consequence of some internal change of the components. This invalidation process yields a new 'version', called epoch here. The epoch is part of the externalized name.
