org.jboss.kernel.spi.dependency
Interface KernelController

All Superinterfaces:

Cloneable, org.jboss.dependency.spi.Controller, org.jboss.util.JBossInterface, KernelEventEmitter, KernelObject

All Known Implementing Classes:

AbstractKernelController, ScopedKernelController

public interface KernelController
extends KernelObject, org.jboss.dependency.spi.Controller

A controller.

The controller is the core component for keeping track of beans to make sure the configuration and lifecycle are done in the correct order including dependencies and classloading considerations.
