本文深入探讨了Strategized Locking设计模式，通过使用可插拔类型的参数化同步机制，有效保护组件的临界部分免受并发访问的影响。详细解释了不同同步策略的实现，如互斥锁、读写锁、信号量等，并展示了如何在组件中实例化这些策略以优化方法实现。

Strategized Locking is another pattern I was very familiar with through working with the third libraries like ACE, POCO an so on. The Strategized Locking design pattern parameterizes synchronization mechanisms that protect a component's critical sections from concurrent access.

Parameterize a component's synchronization aspects by making them 'pluggable' types. Each type objectifies a particular synchronization strategy, such as a mutex, reader/writer lock, semaphore, or 'null' lock. Define instances of these pluggable types as objects contained within a component that can use the objects to synchronize its method implementations efficiently.
