Class ApplicationBundleLoader

java.lang.Object

com.yahoo.container.core.config.ApplicationBundleLoader

public class ApplicationBundleLoader
extends Object

Manages the set of installed and active/inactive bundles. TODO: This class and the CollisionHook currently only handles a "current" and "previous" generation. In order to correctly handle rapid reconfiguration and hence multiple generations, we need to consider the graph generation number for each bundle.
