In other words, a semaphore allows you to implement non-exclusive locking and hence limit concurrency. You might think of a semaphore as a non-exclusive form of a mutex. In .NET, we use the System.Threading.Semaphore class to work with semaphores. Create a mutex in C# Let’s create a ...

explicit semaphore(long long capacity) : _semaphore_count(capacity) { } In the public section of the semaphore class, implement the acquire method. This method decrements the semaphore count as an atomic operation. If the semaphore count becomes negative, add the current context to the end of...

Spinlocks are relatively straightforward to implement using these primitives; but many other issues need to be taken into account in order to implement a robust multithreaded primitive such as a conventional semaphore or mutex. Generally it is preferable to use library functionality rather than reinve...
To support automatic reloading, a class loader must implement the org.apache.catalina.loader.Reloader interface. Tomcat需要自己的加载器的另一个原因是在WEB-INF/classes或WEB-INF/lib目录中的类被修改时支持自动重新加载。 Tomcat加载器实现中的类加载器使用一个独立的线程来不断检查servlet和支持类文件的时间...
