Eseményfügg

Eseményfügg is a Hungarian term used in technical contexts to describe systems, components, or processes that operate in response to events. It is commonly encountered as shorthand for esemenyfüggő or in some cases as eseményvezérelt architectures. The concept denotes behavior that depends on incoming events rather than following a strictly predefined sequence, aligning with what is more widely known as event-driven approaches in computer science.

Etymology and nuance: the word is formed from esemény (event) and függ (to depend), conveying the idea that the operation of the system depends on external stimuli or events. The term is not universally standardized across all Hungarian technical literature, and its precise meaning can vary slightly depending on context and author.

Usage in practice: in software engineering, eseményfüggő characteristics appear in event-driven programming, user interface event handling, and message- or signal-driven architectures. For example, a GUI application registers listeners for user actions; when a button is clicked, an event is generated and handled by a corresponding callback. In distributed systems, services may react to messages on a queue or to changes in state reported by other components, illustrating the event-dependent nature of the workflow. In embedded systems, interrupt-driven routines are often described as eseményfüggő because their execution is triggered by external events such as hardware interrupts.

Relation to related terms: the more standard Hungarian equivalents are eseményvezérelt or esemenény-alapú (event-driven or event-based). Eseményfüggő usage is less common and can be ambiguous, so in formal writing it is advisable to prefer the widely recognized terms to avoid misinterpretation.
