Interface java.beans.beancontext.BeanContextServiceProvider

public abstract interface BeanContextServiceProvider

One of the primary functions of a BeanContext is to act a as rendezvous between JavaBeans, and BeanContextServiceProviders.

A JavaBean nested within a BeanContext, may ask that BeanContext to provide an instance of a "service", based upon a reference to a Java Class object that represents that service.

If such a service has been registered with the context, or one of its nesting context's, in the case where a context delegate to its context to satisfy a service request, then the BeanContextServiceProvider associated with the service is asked to provide an instance of that service.

The ServcieProvider may always return the same instance, or it may construct a new instance for each request.
