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.

public Resource.Factory getFactory(URI uri)
An implementation will (typically) use
the URI's scheme to search the protocol map
and the URI's file extension to search extension 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.
uri - the URI.
ResourceSet.createResource(URI)public java.util.Map getProtocolToFactoryMap()
protocol to
Resource.Factory
or Resource.Factory.Descriptor.
public java.util.Map getExtensionToFactoryMap()
file extension to
Resource.Factory
or Resource.Factory.Descriptor.
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.
