public class ParamSpecOverride : ParamSpec
All operations other than getting or setting the value are redirected, including accessing the nick and blurb, validating a value, and so forth.
See get_redirect_target for retrieving the overridden property. ParamSpecOverride is used in implementing override_property, and will not be directly useful unless you are implementing a new base type similar to GObject.
