Class URLHandlersStreamHandlerProxy
java.lang.Object
java.net.URLStreamHandler
org.apache.felix.framework.URLHandlersStreamHandlerProxy
- All Implemented Interfaces:
- InvocationHandler, URLStreamHandlerSetter
public class URLHandlersStreamHandlerProxy
- extends URLStreamHandler
- implements URLStreamHandlerSetter, InvocationHandler
This class implements a stream handler proxy. When the stream handler
proxy instance is created, it is associated with a particular protocol
and will answer all future requests for handling of that stream type. It
does not directly handle the stream handler requests, but delegates the
requests to an underlying stream handler service.
The proxy instance for a particular protocol is used for all framework
instances that may contain their own stream handler services. When
performing a stream handler operation, the proxy retrieves the handler
service from the framework instance associated with the current call
stack and delegates the call to the handler service.
The proxy will create simple stream handler service trackers for each
framework instance. The trackers will listen to service events in its
respective framework instance to maintain a reference to the "best"
stream handler service at any given time.
