Struct

GObjectTypeClass

Description [src]

struct GTypeClass {
  /* No available fields */
}

An opaque structure used as the base of all classes.

Functions

g_type_class_adjust_private_offset
No description available.
g_type_class_peek

This function is essentially the same as g_type_class_ref(), except that the classes reference count isn’t incremented. As a consequence, this function may return NULL if the class of the type passed in does not currently exist (hasn’t been referenced before).

g_type_class_peek_static

A more efficient version of g_type_class_peek() which works only for static types.

Available since: 2.4

g_type_class_ref

Increments the reference count of the class structure belonging to type. This function will demand-create the class if it doesn’t exist already.

Instance methods

g_type_class_add_private

Registers a private structure for an instantiatable type.

Available since: 2.4

Deprecated since: 2.58

g_type_class_get_instance_private_offset

Gets the offset of the private data for instances of g_class.

Available since: 2.38

g_type_class_get_private
No description available.
g_type_class_peek_parent

This is a convenience function often needed in class initializers. It returns the class structure of the immediate parent type of the class passed in. Since derived classes hold a reference count on their parent classes as long as they are instantiated, the returned class will always exist.

g_type_class_unref

Decrements the reference count of the class structure being passed in. Once the last reference count of a class has been released, classes may be finalized by the type system, so further dereferencing of a class pointer after g_type_class_unref() are invalid.

g_type_class_unref_uncached

A variant of g_type_class_unref() for use in GTypeClassCacheFunc implementations. It unreferences a class without consulting the chain of GTypeClassCacheFuncs, avoiding the recursion which would occur otherwise.
