Feature Type Factory
Identifier:
org.eclipse.update.core.featureTypes
Description:
The platform update mechanism supports pluggable feature type
implementations. A new feature type can be registered in order
to support
alternate packaging and verification schemes.
The featureTypes
extension point allows alternate feature implementations to be
registered using a symbolic type identifier. Whenever the
type is referenced using this identifier, the supplied factory
is used to create the correct concrete feature implementation.
