Class AbstractContext

java.lang.Object

org.jboss.weld.context.AbstractContext

All Implemented Interfaces:

AlterableContext, Context

Direct Known Subclasses:

AbstractManagedContext, AbstractSharedContext

public abstract class AbstractContext
extends java.lang.Object
implements AlterableContext

Base for the Context implementations. Delegates calls to the abstract getBeanStore and getActive to allow for different implementations (storage types and ThreadLocal vs. shared)
