Key Components
- Flyweight Interface or Base Class: This defines the methods for accessing and manipulating the intrinsic state.
- Concrete Flyweight: Implementations of the Flyweight interface that store and manage the intrinsic state. They are typically lightweight and capable of being shared.
- Flyweight Factory: A factory class responsible for creating and managing flyweight objects. It ensures that flyweights are shared and reused when possible.
Flyweight Pattern | C++ Design Patterns
A flyweight pattern is a structural design pattern used to optimize memory usage and performance when dealing with a large number of objects that share some common characteristics. It achieves this by separating an object’s intrinsic state (shared among multiple objects) from its extrinsic state (unique to each object) and storing the intrinsic state externally, typically within a Flyweight factory. This pattern is particularly useful when you need to create a significant number of similar objects and want to minimize the memory footprint.
