MutexLockerml(Heap

jvm源码有很多这种类型写法的代码
MutexLocker ml(Heap_lock);
ObjectWaiter node(Self);
…

上面这种语法，对java程序员应该没接触过

这里以MutexLocker举例

MutexLocker ml(Heap_lock);

class MutexLocker: StackObj { private: Monitor * _mutex; public: MutexLocker(Monitor * mutex) { // MutexLocker ml(Heap_lock); 调用该构造函数 assert(mutex->rank() != Mutex::special, "Special ranked mutex should only use MutexLockerEx"); _mutex = mutex; _mutex->lock(); } .............}

# c++ MutexLocker ml(Heap_lock);# javaMutexLocker ml = new MutexLocker(Heap_lock);
