InterfACe

InterfACe是面向对象编程语言中接口操作的关键字,功能是把所需成员组合起来,用来封装一定功能的集合。它好比一个模板,在其中定义了对象必须实现的成员,通过类或结构来实现它。接口不能直接实例化,即ICountic=newiCount()是错的。接口不能包含成员的任何代码,只定义成员本身。接口成员的具体代码由实现接口的类提供。接口使用InterfACe关键字进行声明。
  • 这是一个演示程序

    这是一个演示程序,原本是我在接口机制学习过程中的随兴之作,源代码相当丑陋,充斥了大量的重复代码,如有好事者愿意将其修改,请务必发给我一份,谢谢。 他没有关于类VMT结构的内容,有此需要者请参考bighawk的delphi类探索,本程序亦大量的参考了其中的代码,特此表示感谢。 他也没有关于接口使用方法的说明,打算入门学习InterfACe的朋友,请参考一些书籍,DFW的savetime兄亦有较好的文章公布,本人也从中受益良多。 这个程序所包含的是,籍由故意设计而成的TInterfACedObject和TMyInterfACedObject2个类,得到4个实例对象,4个接口指针,并且演示了在编译器实现过程中,对象模型的空间状态,接口指针,接口方法表格种种复杂的关系。 如果程序有问题,欢迎来信探讨和指正。

    当客户希望Citrix 服务器能够既提供内部客户端的访问,同时也需要通过路由器上进行NAT(地址转换)的设 置而提供外部客户端的访问,Citrix 要实现这样的应用需要在Web InterfACe 中进行必要的设置才能够支持

    This is the source for a C compiler that generates 386 or m68K code. Code generation is fairly good although the optimizer is a little naive... the code itself should be highly portable although there are some issues involved with porting from MSDOS that have to be resolved for example the size of LONG on unix machines is so big some of the code generated gets messed up. Code generation requires TASM to assemble the compiler output you can use the borland TLINK to produce executables, or the Watcom WLINK can also be used. PMODE systems written by TRAN are used for the DPMI InterfACe.

    c8051f340 串口 程序This program demonstrates how to configure the C8051F340 to use routines in STDIO.h to write to and read from the UART InterfACe. The program reads a character using the STDIO routine getkey(), outputs that character to the screen, and then outputs the ASCII hex value of that character.

    This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air InterfACe for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.
