stack reference

If the method is not static, I generate code to load the this object reference to the stack, and also set the method call type to virtual ( rather than static).

如果方法不是静态的，那么就生成将this对象引用装载到堆栈中的代码，同时设置方法调用类型为virtual（而不是static）。

An object reference ( or pointer ) is pushed onto the stack.

将对象引用 ( 或指针 ) 推送到堆栈上.

Without a reference, you copy the entire array or hash onto the function call stack, and then copy it again in the function.

如果不使用引用，就需要将整个数组或hash表复制到该函数的调用栈中，然后在函数中再次对其进行复制。

Service primitive and command frame are prototypes and reference specifications for design of protocol stack. At last, this paper studies and analyzes primitives and command frames in 802.15.4/ ZigBee, and realizes relevant primitives and command frames of ZTF-MAC.

服务原语和命令帧的设计是通信标准协议栈设计的原型和参考规范，本文最后研究和分析了802.15.4/ZigBee协议规范中的服务原语和命令帧，并为ZTF-MAC设计实现了相关的原语和命令帧。
