Flyweight Pattern

Flyweight Pattern is a structural design pattern that uses sharing to support large numbers of fine-grained objects efficiently. It lets you minimize memory usage and improve performance by sharing common objects instead of creating new ones. This pattern is particularly useful when your application has a large number of similar objects that don't need to be unique. Flyweight Pattern promotes object reuse and reduces object creation overhead.

Key Concepts

The Flyweight Pattern involves several key concepts to achieve object sharing and efficient memory management:

• Flyweight: Represents the shared, lightweight object. It contains the common state shared among multiple objects.
• Concrete Flyweight: Implements the Flyweight interface and defines the specific behavior of different flyweight objects.
• Flyweight Factory: Creates and manages flyweight objects. It ensures that shared flyweight objects are reused instead of creating new ones.
• Client: Uses flyweight objects to perform operations without needing to create or manage them directly.
