https://manisdump.dev Independent writing on systems & software, published occasionally by Mani. https://manisdump.dev/#post-behavioral-patterns https://manisdump.dev/#post-behavioral-patterns Mon, 13 Jul 2026 00:00:00 GMT To define efficient, flexible, and loosely coupled communication channels. https://manisdump.dev/#post-builder-pattern https://manisdump.dev/#post-builder-pattern Mon, 13 Jul 2026 00:00:00 GMT It extracts object construction into a readable, step-by-step process. https://manisdump.dev/#post-creational-patterns https://manisdump.dev/#post-creational-patterns Mon, 13 Jul 2026 00:00:00 GMT It abstract the object creation process, giving you more flexibility and control over how and when objects are instantiated. https://manisdump.dev/#post-decorator-pattern https://manisdump.dev/#post-decorator-pattern Mon, 13 Jul 2026 00:00:00 GMT Allowing you to attach new behaviors to individual objects dynamically at runtime, without altering the underlying class code. https://manisdump.dev/#post-facade-pattern https://manisdump.dev/#post-facade-pattern Mon, 13 Jul 2026 00:00:00 GMT The Facade pattern provides a simplified, high-level interface to a complex subsystem. It hides the complexity of the underlying system from the client. https://manisdump.dev/#post-factory-pattern https://manisdump.dev/#post-factory-pattern Mon, 13 Jul 2026 00:00:00 GMT It acts as a buffer between your code and the objects it needs to create. https://manisdump.dev/#post-gof-patterns https://manisdump.dev/#post-gof-patterns Mon, 13 Jul 2026 00:00:00 GMT The GoF book categorizes the 23 design patterns into three distinct families based on their primary purpose. Understanding these categories is the first step to knowing when to apply which pattern. https://manisdump.dev/#post-iterator-pattern https://manisdump.dev/#post-iterator-pattern Mon, 13 Jul 2026 00:00:00 GMT Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation. https://manisdump.dev/#post-proxy-pattern https://manisdump.dev/#post-proxy-pattern Mon, 13 Jul 2026 00:00:00 GMT It acts as a surrogate or placeholder for another object to control access to it. https://manisdump.dev/#post-singleton-pattern https://manisdump.dev/#post-singleton-pattern Mon, 13 Jul 2026 00:00:00 GMT It matters because sometimes your software strictly requires exactly one instance of an object to coordinate actions across the entire system. https://manisdump.dev/#post-structural-patterns https://manisdump.dev/#post-structural-patterns Mon, 13 Jul 2026 00:00:00 GMT The fundamental driving force behind structural patterns is how they assemble objects. https://manisdump.dev/#post-template-method-pattern https://manisdump.dev/#post-template-method-pattern Mon, 13 Jul 2026 00:00:00 GMT The Template Method pattern is your best defense against duplicated boilerplate code in algorithms. When you have multiple processes that follow the exact same sequence of steps, but differ slightly in how they execute one or two of those steps, this pattern lets you lock down the workflow while keeping the details flexible. https://manisdump.dev/#post-visitor-pattern https://manisdump.dev/#post-visitor-pattern Mon, 13 Jul 2026 00:00:00 GMT The Visitor Pattern solves a very specific architectural headache: how do you add new behavior to a complex hierarchy of objects without modifying their source code? https://manisdump.dev/#post-working-example-for-creational-pattern https://manisdump.dev/#post-working-example-for-creational-pattern Mon, 13 Jul 2026 00:00:00 GMT Real-time examples to describe creational patterns
