Interface BeanContextServiceProvider

All Known Implementing Classes:

BeanContextServicesSupport.BCSSProxyServiceProvider

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.

Method Summary

Iterator	getCurrentServiceSelectors(BeanContextServices bcs, Class serviceClass)
Object	getService(BeanContextServices bcs, Object requestor, Class serviceClass, Object serviceSelector) request an instance of a service,
void	releaseService(BeanContextServices bcs, Object requestor, Object service) release the service
