Home / cs-notes / Design / Design Patterns / Summary / Flyweight vs Object Pool

Intent

• Flyweight
  • Use sharing to support large numbers of similar objects
• Object Pool
  • Avoid expensive acquisition and release of resources by recycling objects

Implementation

• Flyweight
  • Intern to keep each object unique and immutable
• Object Pool
  • each object may be borrowed and returned, but not unique or immutable
