Kotlin Design Patterns: Template Method Explained
Behavioral Design Pattern Overriding only a specific algorithm step without changing its general structure. You have a general algorithm structure in the superclass, but make one of the abstract steps so that the subclasses must implement it. It’s used to either create variants of the…
Kotlin Design Patterns: Strategy Explained
Behavioral Design Pattern Selection of algorithm in runtime. Instead of implementing algorithms directly in place of use, create a separate class for each algorithm and treat them like a family. Depending on the conditions, you’ll want to swap the algorithm you used. What do we…
Kotlin Design Patterns: Iterator Explained
Behavioral Design Pattern Iterator lets you traverse through Collections of elements without exposing the Collection type and traversing direction. The Iterating Responsibility is delegated to separate objects. It’s beneficial when dealing with complex structures like Graphs where you can iterate over the elements in more…
Kotlin Design Patterns: Mediator | ProAndroidDev
Behavioral Design Pattern Mediator is made for 1 thing only: Reducing Chaos between dependencies. Objects, instead of communicating with each other directly, will communicate through the Mediator. What do we get from that? Less coupled code: classes don’t use multiple external dependencies. Reusability: classes don’t…
Kotlin Design Patterns: Proxy Explained
STRUCTURAL DESIGN PATTERNS Proxy is a wrapper for an object that is used behind the scenes. This means that it can provide additional logic for that object. Both the proxy and the object implement the same interface. It’s mostly used when additional access control is…
Kotlin Design Patterns: Facade Explained
Structural Patterns Facade is the front-facing object that hides more complexity underneath it. Instead of working with multiple related interfaces you work with a single higher-level abstraction object that does multiple things. Facade class diagram As shown in the diagram, Application uses Facade instead of…
Kotlin Design Patterns: Decorator Explained
Structural Patterns When an object needs to have behavior added and removed dynamically at Runtime, it’s also an alternative to extending classes by choosing Composition over Inheritance. It’s also commonly named Wrapper, as it says more about what it does in reality. Decorator Class Diagram…
Kotlin Design Patterns: Bridge Explained
Structural Design Patterns The primary purpose of this pattern is to split a class into two abstract hierarchies of classes so that they can grow independently. It separates the responsibilities of a single class into multiple classes with a single responsibility. Consider using this pattern…
Dot. Dash. Design. Mastering Lines in Jetpack Compose with… | by Katie Barnett | Mar, 2024
Mastering Lines in Jetpack Compose with PathEffect Pretty morse code perhaps? Often when creating a UI in Jetpack Compose we need to draw lines. Sometimes as dividers to break up some space or aesthetically as part of more complex shapes or designs. We don’t always…
Blurring the Lines: How to Achieve a Glassmorphic Design with Jetpack Compose | by Zakir Sheikh | Jan, 2024
Computers have come a long way since their inception. From bulky machines that occupied entire rooms and performed simple calculations, to sleek devices that fit in our pockets and run complex applications, computers have evolved to meet the changing needs and expectations of users. One…
