Efl UI Factory that provides object caching.
This factory handles caching of one type of object that must be an Efl.Gfx.Entity with an Efl.Ui.View interface defined. This factory will rely on its parent class Efl.Ui.Widget_Factory for creating the subset of class that match the Efl.Ui.Widget interface. The factory will automatically empties the cache when the application goes into pause.
Creating objects is costly and time consuming, keeping a few on hand for when you next will need them helps a lot. This is what this factory caching infrastructure provides. It will create the object from the class defined on it and set the parent and the model as needed for all created items. The View has to release the Item using the release function of the Factory interface for all of this to work properly.
The cache might decide to flush itself when the application event pause is triggered.
Implement this method to finish the initialization of your object after all (if any) user-provided configuration methods have been executed.
Efl_Object *efl_finalize(Eo *obj);
Implement this method to perform special actions when your object loses its parent, if you need to.
void efl_invalidate(Eo *obj);
Define the class of the item returned by this factory.
const Efl_Class *efl_ui_widget_factory_item_class_get(const Eo *obj); void efl_ui_widget_factory_item_class_set(Eo *obj, const Efl_Class *klass);
items_limit (get, set)
Define how many maximum number of items are waiting on standby in the cache.
unsigned int efl_ui_caching_factory_items_limit_get(const Eo *obj); void efl_ui_caching_factory_items_limit_set(Eo *obj, unsigned int limit);
memory_limit (get, set)
Define the maximum size in Bytes that all the objects waiting on standby in the cache can take. They must provide the Efl.Cached.Item interface for an accurate accounting.
unsigned int efl_ui_caching_factory_memory_limit_get(const Eo *obj); void efl_ui_caching_factory_memory_limit_set(Eo *obj, unsigned int limit);
bind property data with the given key string. when the data is ready or changed, bind the data to the key action and process promised work.
Eina_Error efl_ui_property_bind(Eo *obj, const char *key, const char *property);
Release a UI object and disconnect from models.
void efl_ui_factory_release(Eo *obj, Eina_Iterator *ui_views);
Create a UI object from the necessary properties in the specified model.
Eina_Future *efl_ui_factory_create(Eo *obj, Eina_Iterator *models);
|future_rejected||Creates a new future that is already rejected to a specified error using the Efl.Loop_Consumer.loop.get.|
|future_resolved||Creates a new future that is already resolved to a value.|
|parent (get, set)||The parent of an object.|
|promise_new||Create a new promise with the scheduler coming from the loop provided by this object.|
|allow_parent_unref (get, set)||Allow an object to be deleted by unref even if it has a parent.|
|children_iterator_new||Get an iterator on all children.|
|comment (get, set)||A human readable comment for the object.|
|composite_attach||Make an object a composite object of another.|
|composite_detach||Detach a composite object from another object.|
|composite_part_is||Check if an object is part of a composite object.|
|debug_name_override||Build a read-only name for this object used for debugging.|
|destructor||Implement this method to provide deinitialization code for your object if you need it.|
|event_callback_forwarder_del||Remove an event callback forwarder for a specified event and object.|
|event_callback_forwarder_priority_add|| Add an event callback forwarder that will make this object emit an event whenever another object (
|event_callback_stop||Stop the current callback call.|
|event_freeze||Freeze events of this object.|
| ||event_global_freeze||Globally freeze events for ALL EFL OBJECTS.|
| ||event_global_freeze_count (get)|
| ||event_global_thaw||Globally thaw events for ALL EFL OBJECTS.|
|event_thaw||Thaw events of object.|
|name (get, set)||The name of the object.|
|name_find||Find a child object with the given name and return it.|
|provider_find||Searches upwards in the object tree for a provider which knows the given class/interface.|
|provider_register||Will register a manager of a specific class to be answered by Efl.Object.provider_find.|
|provider_unregister||Will unregister a manager of a specific class that was previously registered and answered by Efl.Object.provider_find.|
|constructor||Implement this method to provide optional initialization code for your object.|
|factory_bind||bind the factory with the given key string. when the data is ready or changed, factory create the object and bind the data to the key action and process promised work. Note: the input Efl.Ui.Factory need to be Efl.Ui.Property_Bind.property_bind at least once.|
| ||part_get||Get a proxy object referring to a part of an object.|
|del||Object is being deleted. See Efl.Object.destructor.|
|destruct||Object has been fully destroyed. It can not be used beyond this point. This event should only serve to clean up any reference you keep to the object.|
|invalidate||Object is being invalidated and losing its parent. See Efl.Object.invalidate.|
|noref||Object has lost its last reference, only parent relationship is keeping it alive. Advanced usage.|
|ownership,shared||Object has acquired a second reference. It has multiple owners now. Triggered whenever increasing the refcount from one to two, it will not trigger by further increasing the refcount beyond two.|
|ownership,unique||Object has lost a reference and only one is left. It has just one owner now. Triggered whenever the refcount goes from two to one.|
|item,building||Event triggered when an item has processed Efl.Object.finalize, but before all the factory are done building it. Note: if the Efl.Ui.Factory does keep a cache of object, this will be called when object are pulled out of the cache.|
|item,constructing||Event triggered when an item is under construction (between the Efl.Object.constructor and Efl.Object.finalize call on the item). Note: If the Efl.Ui.Factory does keep a cache of objects, this won't be called when objects are pulled out of the cache.|
|item,created||Event triggered when an item has been successfully created by the factory and is about to be used by an Efl.Ui.View.|
|item,releasing||Event triggered when an item is being released by the Efl.Ui.Factory. It must be assumed that after this call, the object can be recycle to another Efl.Ui.View and there can be more than one call for the same item.|
|properties,changed||Event dispatched when a property on the object has changed due to a user interaction on the object that a model could be interested in.|
|property,bound||Event dispatched when a property on the object is bound to a model. This is useful to avoid generating too many events.|
