public static interface Resource.Factory.Registry
A registry of resource factories.
A registry implementation will typically delegate to the global instance, which can be used as follows
Resource.Factory.Registry.INSTANCE.getProtocolToFactoryMap().
put("abc", resourceFactoryForURIWithAbcProtocol);
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().
put("xyz", resourceFactoryForURIWithXyzFileExtension);
A descriptor can be used in place of an actual factory
as a value in the map.
It is used for factories registered via
plugin registration
to ensure delayed plugin load.
Clients must extend the default implementation,
since methods can and will be added to this API.

Resource.Factory getFactory(URI uri)
An implementation will (typically) use
the URI's scheme to search the protocol map
the URI's file extension to search extension map,
and the URI's content type identifier to search the content type map.
It will convert
a resulting descriptor into a factory.
It may choose to provide additional mechanisms and algorithms to determine a factory appropriate for the given URI.

The default file extension "*"
can be registered as a default that matches any file extension.
This is typically reserved for a default factory that supports XMI serialization;
clients are strongly discouraged from using this feature in the global registry,
particularly those that must function effectively within an Eclipse environment.
