JVM学习笔记-本地方法调用(Invoking a Native Method)

Invoking a Native Method

As mentioned in Chapter 5, "The Java Virtual Machine," the virtual machine invokes native methods in an implementation dependent manner. When invoking a native method, the virtual machine does not push a new stack frame onto the Java stack for the native method. At the point in which the thread enters the native method, it leaves the Java stack behind. When the native method returns, the Java stack will once again be used.

 

如第5章所述，虚拟机使用一种“与实现相关”的风格调用本地方法。当调用本地方法时，虚拟机不会将一个新的栈帧压入Java栈。当线程进入到本地方法的那一刻，它就将Java栈抛在身后。直到本地方法返回以后，Java栈才被重新使用。
