Sündmustepõhise

Sündmustepõhise, often translated as event-driven, refers to a programming paradigm or architectural style where the flow of the program is determined by occurrences of events. An event can be any significant change in state or a user action, such as a mouse click, a key press, a message arriving, or a sensor reading. When an event occurs, the system responds by executing a specific piece of code, known as an event handler or listener.

This approach contrasts with traditional procedural programming where the program executes a sequence of instructions in a predefined order. In an event-driven system, components communicate by emitting and reacting to events. This makes the system highly responsive and allows for flexible and modular designs. Common examples of event-driven systems include graphical user interfaces (GUIs), where user interactions trigger actions, and real-time systems, where external stimuli must be processed immediately.

The core components of an event-driven system typically include an event source, which generates events, an event dispatcher or loop, which monitors for events and routes them to the appropriate handlers, and event handlers, which are functions or methods that execute in response to specific events. This paradigm is widely used in modern software development due to its ability to manage complex interactions and asynchronous operations efficiently.
