Efl.Loop_Handler (class)

Description

An object that describes an low-level source of I/O to listen to for available data to be read or written, depending on the OS and data source type. When I/O becomes available various events are produced and the callbacks attached to them will be called.

Inheritance

Members

active (get, set)

This sets what kind of I/O should be listened to only when using a fd or fd_file for the handler
Efl_Loop_Handler_Flags efl_loop_handler_active_get(const Eo *obj);
void efl_loop_handler_active_set(Eo *obj, Efl_Loop_Handler_Flags flags);


constructor [Overridden from Efl.Object]

Implement this method to provide optional initialization code for your object.
Efl_Object *efl_constructor(Eo *obj);


destructor [Overridden from Efl.Object]

Implement this method to provide deinitialization code for your object if you need it.
void efl_destructor(Eo *obj);


fd (get, set)

Controls a file descriptor to listen to for I/O, which points to a data pipe such as a device, socket or pipe etc.
int efl_loop_handler_fd_get(const Eo *obj);
void efl_loop_handler_fd_set(Eo *obj, int fd);


fd_file (get, set)

Controls a file descriptor to listen to for I/O that specifically points to a file in storage and not a device, socket or pipe etc.
int efl_loop_handler_fd_file_get(const Eo *obj);
void efl_loop_handler_fd_file_set(Eo *obj, int fd);


finalize [Overridden from Efl.Object]

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);


parent (get, set) [Overridden from Efl.Object]

The parent of an object.
Efl_Object *efl_parent_get(const Eo *obj);
void efl_parent_set(Eo *obj, Efl_Object *parent);


win32 (get, set)

Controls a windows win32 object handle to listen to for I/O. When it becomes available for any data the read event will be produced.
void *efl_loop_handler_win32_get(const Eo *obj);
void efl_loop_handler_win32_set(Eo *obj, void *handle);


Inherited

Efl.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.
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 (source) emits it. The event is said to be forwarded from source to this object.
event_callback_stop Stop the current callback call.
event_freeze Freeze events of this object.
event_freeze_count (get)
static event_global_freeze Globally freeze events for ALL EFL OBJECTS.
static event_global_freeze_count (get)
static event_global_thaw Globally thaw events for ALL EFL OBJECTS.
event_thaw Thaw events of object.
finalized (get)
invalidate Implement this method to perform special actions when your object loses its parent, if you need to.
invalidated (get)
invalidating (get)
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.

Events

buffer

Called when buffered data already read from the descriptor should be processed.
EFL_LOOP_HANDLER_EVENT_BUFFER(void)


error

Called when a error occurrs on the descriptor.
EFL_LOOP_HANDLER_EVENT_ERROR(void)


prepare

Called when preparing a descriptor for listening.
EFL_LOOP_HANDLER_EVENT_PREPARE(void)


read

Called when a read occurs on the descriptor.
EFL_LOOP_HANDLER_EVENT_READ(void)


write

Called when a write occurs on the descriptor.
EFL_LOOP_HANDLER_EVENT_WRITE(void)


Inherited

Efl.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.
