## org.eclipse.gemini.blueprint.extender.internal.dependencies.shutdown
Class ShutdownSorter

    java.lang.Object
      org.eclipse.gemini.blueprint.extender.internal.dependencies.shutdown.ShutdownSorter

    public abstract class ShutdownSorter

extends Object

Utility for sorting out bundles during shutdown based on the OSGi 4.2 shutdown algorithm. Please see section 121.3.11 in OSGi 4.2 release. Since sorting out the entire graph from the beginning is difficult (shutting down some bundles, might allow others to be destroyed), this utility is meant to be called multiple times until the list is being depleted.
