public @interface URLStreamHandlerRegistration

Replacement for URLStreamHandlerFactory within the NetBeans platform. (The JVM only permits one global factory to be set at a time, whereas various independent modules may wish to register handlers.) May be placed on a URLStreamHandler implementation to register it. Your handler will be loaded and used if and when a URL of a matching protocol is created.

A URLStreamHandlerFactory which uses these registrations may be found in Lookup.getDefault(). This factory is active whenever the module system is loaded. You may also wish to call URL.setURLStreamHandlerFactory(java.net.URLStreamHandlerFactory) from a unit test or otherwise without the module system active.
