Provides classes and interfaces relating to bean context. A bean context is a container for beans and defines the execution environment for the beans it contains. There can be several beans in a single bean context, and a bean context can be nested within another bean context. This package also contains events and listener interface for beans being added and removed from a bean context.
PackageDescriptionContains classes related to developing beans -- components based on the JavaBeans architecture.
InterfaceDescriptionThe BeanContext acts a logical hierarchical container for JavaBeans.JavaBeans wishing to be nested within, and obtain a reference to their execution environment, or context, as defined by the BeanContext sub-interface shall implement this interface.This interface is implemented by
BeanContextChildrenthat have an AWT
Componentassociated with them.This interface is implemented by BeanContexts' that have an AWT Container associated with them.Compliant BeanContexts fire events on this interface when the state of the membership of the BeanContext changes.This interface is implemented by a JavaBean that does not directly have a BeanContext(Child) associated with it (via implementing that interface or a subinterface thereof), but has a public BeanContext(Child) delegated from it.One of the primary functions of a BeanContext is to act a as rendezvous between JavaBeans, and BeanContextServiceProviders.A BeanContextServiceProvider implementor who wishes to provide explicit information about the services their bean may provide shall implement a BeanInfo class that implements this BeanInfo subinterface and provides explicit information about the methods, properties, events, etc, of their services.The listener interface for receiving
BeanContextServiceRevokedEventobjects.The BeanContextServices interface provides a mechanism for a BeanContext to expose generic "services" to the BeanContextChild objects within.The listener interface for receiving
ClassDescriptionThis is a general support class to provide support for implementing the BeanContextChild protocol.
BeanContextEventis the abstract root event class for all events emitted from, and pertaining to the semantics of, a
BeanContextMembershipEventencapsulates the list of children added to, or removed from, the membership of a particular
BeanContext.This event type is used by the BeanContextServicesListener in order to identify the service being registered.This event type is used by the
BeanContextServiceRevokedListenerin order to identify the service being revoked.This helper class provides a utility implementation of the java.beans.beancontext.BeanContextServices interface.subclasses may subclass this nested class to add behaviors for each BeanContextServicesProvider.This helper class provides a utility implementation of the java.beans.beancontext.BeanContext interface.protected final subclass that encapsulates an iterator but implements a noop remove() method.
