Flyweight Pattern
The Flyweight pattern minimizes memory usage by sharing as much data as possible with similar objects, particularly useful for handling large numbers of similar objects efficiently.
The Flyweight pattern is a structural design pattern that aims to minimize memory usage by sharing as much data as possible with other similar objects. It's particularly useful when an application needs to create a large number of similar objects, such as rendering thousands of UI elements, managing game entities, or handling large datasets. The pattern separates intrinsic state (shared) from extrinsic state (unique) [citation:6].
