Java: notify() vs. notifyAll() all over again
...one of threads is notified to wake up, execute the next job and go back to sleep.
Use notifyAll() for other cases where the waiting threads may have different purposes and should be able to run concurrently. An example is a maintenance operation on a shared resource, where multiple threads are waiti...

...。由于标准的C++没有属性访问器，只能添加一个两个存取函数来实现对属性的访问，通过在属性名称前加上get_和put_前缀分别实现对属性的读写操作。即，由VC自动完成C++类对接口的封装。
