Module dagon.core.event

Primitives and tools for event-driven programming.

Description

The dagon.core.event module defines the EventType enumeration, the Event struct, the EventManager class for event polling and storing, and the EventListener base class for handling events.

EventManager is single-threaded. For multi-threaded event/message passing, use MessageBroker.

Functions

Name	Description
`messageEvent(sender, recipient, message, payload, domain)`	Constructs a message event.
`taskEvent(sender, recipient, callback, payload, domain)`	Constructs a task event.

Interfaces

Name	Description
`InputDevice`	Interface for input event emitters. Implementations of this interface can generate events using `EventManager.addEvent` method.

Classes

Name	Description
`EventDispatcher`	Base class for event dispatchers.
`EventListener`	Base class for single-threaded event listeners.
`EventManager`	Manages event polling, event queue and input state.

Structs

Name	Description
`Event`	Represents a single event in the Dagon event system. Contains event type and relevant data for the event.
`GameInputDevice`	A structure that represents game input device.

Enums

Name	Description
`EventType`	All supported event types in Dagon.
`GameInputDeviceType`	Enumeration of supported game input device types.
`MessageDomain`	Communication layer `Event` is subject to. Circular - event goes to both message broker and main-thread event listeners; ITC - event goes to the message broker; MainThread - event goes to main-thread event listeners.

Manifest constants

Name	Type	Description
`MAX_CONTROLLERS`		Maximum number of supported controllers.

Aliases

Name	Type	Description
`TaskCallback`	`void delegate(Object, void*)`	A delegate that can be used as an asynchronous callback in task events. `executor` parameter is meant to be the object that executes the task. `payload` is user-defined pointer passed with the event.
