GI.GObject.Structs.ParamSpecPool

A ParamSpecPool maintains a collection of GParamSpecs which can be quickly accessed by owner and name.

The implementation of the Object property system uses such a pool to store the GParamSpecs of the properties all object types.

Exported types

newtype ParamSpecPool

Memory-managed wrapper type.
