GValue provides an abstract container structure which can be copied, transformed and compared while holding a value of any (derived) type, which is registered as a GType with a GTypeValueTable in its GTypeInfo structure. Parameter specifications for most value types can be created as GParamSpec derived instances, to implement e.g. GObject properties which operate on GValue containers.
