TypeInfo
- class TypeInfo(*args, **kwargs)
This structure is used to provide the type system with the information required to initialize and destruct (finalize) a type’s class and its instances.
The initialized structure is passed to the type_register_static()
function
(or is copied into the provided TypeInfo
structure in the
complete_type_info()
). The type system will perform a deep
copy of this structure, so its memory does not need to be persistent
across invocation of type_register_static()
.
Fields
- class TypeInfo
- base_finalize
Location of the base finalization function (optional)
- base_init
Location of the base initialization function (optional)
- class_data
User-supplied data passed to the class init/finalize functions
- class_finalize
Location of the class finalization function for classed and instantiatable types. Location of the default vtable finalization function for interface types. (optional)
- class_init
Location of the class initialization function for classed and instantiatable types. Location of the default vtable inititalization function for interface types. (optional) This function is used both to fill in virtual functions in the class or default vtable, and to do type-specific setup such as registering signals and object properties.
- class_size
Size of the class structure (required for interface, classed and instantiatable types)
- instance_init
Location of the instance initialization function (optional, for instantiatable types only)
- instance_size
Size of the instance (object) structure (required for instantiatable types only)
- n_preallocs
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 this field is ignored.
- value_table
A
TypeValueTable
function table for generic handling of GValues of this type (usually only useful for fundamental types)
