In an ESP pipeline, an event is anything that is created from an event source, recordable and analyzable. The event source could be an enterprise system, a business process, an internet of things (IoT) sensor, a
Event-driven programming separates event-processing logic from the rest of a program's code. The event-driven approach contrasts with batch processing. Because event-driven programming is a general development approach rather than a type of language, event-driven apps can be created in any programmi...
Event-Driven Program An event-driven program is one that largely responds to user events or other similar input. The concept of event-driven programming is an important one in application development and other kinds of programming, and has spawned the emergence of event handlers and other resources...
Event-stream processing (ESP) is a group of technologies engineered to facilitate the generation of event-driven information systems. ESP is comprised of basic elements like event visualization, event databases, event-driven middleware and event processing languages (also known as complex event processin...
when you attach an event listener to an element or object, it waits for a particular event to occur. when the event is triggered, the listener executes a specified function or block of code. this function can perform various actions, such as updating the user interface, processing data, or...
In this tutorial, we’ll start with the basic principles and origins of reactive programming. Reactive programming is a declarative programming paradigm that is based on the idea of asynchronous event processing and data streams. Today, reactive programming is used in many different areas, such as...
An API, or application programming interface, is a set of rules and protocols that allows applications to exchange data, perform actions, and interact in a well-documented way. When a request is made—for a weather update, say—the API processes the request, executes the necessary actions, an...
The event model is discussed in Chapter 3. Improved XML handling Working with complex XML documents is a pleasure with ActionScript 3.0. It allows you to reference XML data the same way you reference properties of other objects, such as movie clips or buttons, using a similar syntax. You’...
The event could be a message sent from other programs, a sensor trigger, or a user action, such as a key press or a mouse click. Unlike data-driven programming, event-driven programming can generally be applied using any programming language. What Is the Difference between Data-Driven and ...
What is kernel-level programming in an OS? Kernel-level programming involves writing software that interacts directly with the operating system's core functions (the kernel). This type of programming requires specialized knowledge and can be used to create device drivers, security software, and other...
