Interface

GckObjectCache

Description [src]

interface Gck.ObjectCache : Gck.Object

An interface implemented by derived classes of GckObject to indicate which attributes they’d like an enumerator to retrieve.

These attributes are then cached on the object and can be retrieved through the GckObjectCache:attributes property.

Prerequisite

In order to implement ObjectCache, your type must inherit fromGckObject.

Instance methods

gck_object_cache_fill

Adds the attributes to the set cached on this object. If an attribute is already present in the cache it will be overridden by this value.

gck_object_cache_get_attributes

Gets the attributes cached on this object.

gck_object_cache_set_attributes

Sets the attributes cached on this object.

gck_object_cache_update

Update the object cache with given attributes. If an attribute already exists in the cache, it will be updated, and if it doesn’t it will be added.

gck_object_cache_update_async

Update the object cache with given attributes. If an attribute already exists in the cache, it will be updated, and if it doesn’t it will be added.

gck_object_cache_update_finish

Complete an asynchronous operation to update the object cache with given attributes.

Properties

Interface structure

struct GckObjectCacheIface {
  GTypeInterface interface;
  gulong default_types;
  gint n_default_types;
  void (* fill) (
    GckObjectCache* object,
    GckAttributes* attrs
  );
  
}

Interface for GckObjectCache. If the default_types field is implemented by a implementing class, then that will be used by a GckEnumerator which has been setup using gck_enumerator_set_object_type()

The implementation for populate should add the attributes to the cache. It must be thread safe.

Interface members

	Virtual method to add attributes to the cache.

Virtual methods

Gck.ObjectCache.fill

Adds the attributes to the set cached on this object. If an attribute is already present in the cache it will be overridden by this value.
