        AEEvent
Most base class for all AccessEngine events. Supports the concept of a priority which may be used to prioritize event execution.

Method Details [hide private]

__init__(self, priority=AEConstants.EXEC_NORMAL, focused=False, **kwargs)
(Constructor)

source code 
Stores the event priority and whether the event source was focused or not.
Parameters:
  • priority (integer) - Priority of this event, defaults to normal
  • focused (boolean) - Was the source of the event focused at the time of event creation?
Overrides: object.__init__

__str__(self)
(Informal representation operator)

source code 
Returns the name of this event.
Returns: string
Class name of this AEEvent
Overrides: object.__str__

execute(self)

source code 

Executes the logic that will handle this event. The AEEventManager can provide whatever arguments are necessary for an AEEvent subclass to execute as keyword arguments. It is up to the subclass to unpack and use the arguments it needs by name.

See AccessEngine.AEEventManager._AEEventManager._executeEvent for the arguments provided.
Returns: boolean
Was this class able to execute successfully? Always True here.

getPriority(self)

source code 
Returns: integer
Current priority value

setPriority(self, priority)

source code 
Parameters:
  • priority (integer) - New priority value

setLayer(self, layer)

source code 
Parameters:
  • layer (integer) - Layer of this event (focus, tier, background)

getLayer(self)

source code 
Gets the layer for this event. If the AEPor is marked as imcomplete, builds a complete AEPor and then determines if the proper AEPor is in a different layer than the one originally computed.
Returns: integer
Gets the layer for this event

getDataForTask(self)

source code 
Fetches data out of an AEEvent for use by a task. This method must be implemented by any AEEvent that will be handled by AETierManager.manageEvent or AETierManager.manageGesture.
Returns: dictionary
Empty dictionary

getTimestamp(self)

source code 
Gets the timestamp for when the event occurred.
Returns: float
Always zero when not overridden

getPOR(self)

source code 
Returns: AEPor
Point of regard associated with this event

getAppID(self)

source code 
Returns: opaque object
Unique application ID identifying the top most container for the source of this event (i.e. the application)
