Flyweight

What problem does it solve?

Flyweight pattern reduces memory usage by sharing intrinsic state across a large number of fine-grained objects, enabling scalable object creation and rendering.

Core Features & Use Cases

• Shared intrinsic state to minimize memory footprint across millions of objects (e.g., font glyphs, icons, game particles).
• Clear separation of intrinsic (shared) vs extrinsic (contextual) state to ensure safe reuse.
• A lightweight factory or pool that reuses existing instances and prevents unnecessary duplication.

Quick Start

Create a FlyweightFactory and render many objects by supplying external state for each instance.
