@Generated("org.javagi.JavaGI") public class ParamSpecTypeInfo extends ProxyInstance

This structure is used to provide the type system with the information required to initialize and destruct (finalize) a parameter's class and instances thereof.

The initialized structure is passed to the g_param_type_register_static() The type system will perform a deep copy of this structure, so its memory does not need to be persistent across invocation of g_param_type_register_static().
