Sündmuspõhiseid

Sündmuspõhised, also known as event-based or event-driven systems, are computational models where the flow of the program is determined by events such as user actions, sensor outputs, or messages from other programs or threads. This approach contrasts with traditional, linear programming models where the program follows a predetermined sequence of instructions.

In a sündmuspõhise system, the program waits for an event to occur, processes the event, and then returns to a waiting state. This model is particularly useful in applications that require real-time responses, such as graphical user interfaces, network servers, and embedded systems. For instance, a click on a button in a graphical user interface generates an event that the program must handle.

The key components of a sündmuspõhise system include event sources, event listeners, and event handlers. Event sources are objects that generate events, such as a user clicking a mouse or a timer expiring. Event listeners are objects that register their interest in specific types of events. Event handlers are functions or methods that are called in response to an event.

One of the main advantages of sündmuspõhise programming is its ability to handle multiple, asynchronous events efficiently. This makes it well-suited for applications that need to respond to user inputs or other external stimuli in real-time. However, it can also introduce complexity, as the flow of the program is no longer linear and can be harder to predict and debug.

Sündmuspõhised systems are widely used in various domains, including web development, game programming, and robotics. They are a fundamental concept in modern software design and are supported by many programming languages and frameworks.
