GObject.ParamSpecTypeInfo

Fields

Name	Type	Access	Description
finalize	object	r	The instance finalization function (optional).
instance_init	object	r	Location of the instance initialization function (optional).
instance_size	int	r/w	Size of the instance (object) structure.
n_preallocs	int	r/w	Prior to GLib 2.10, it specified the number of pre-allocated (cached) instances to reserve memory for (0 indicates no caching). Since GLib 2.10, it is ignored, since instances are allocated with the slice allocator now.
value_set_default	object	r	Resets a value to the default value for pspec (recommended, the default is GObject.Value.reset()), see GObject.param_value_set_default().
value_type	GObject.GType	r/w	The GObject.GType of values conforming to this GObject.ParamSpec
value_validate	object	r	Ensures that the contents of value comply with the specifications set out by pspec (optional), see GObject.param_value_validate().
values_cmp	object	r	Compares value1 with value2 according to pspec (recommended, the default is memcmp()), see GObject.param_values_cmp().

Details

class GObject.ParamSpecTypeInfo

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 GObject.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 GObject.param_type_register_static().
