译序(侯捷) ix 导读(Introduction) 001 基础议题(Basics) 009 条款1:仔细区别 pointers 和 references 009 Distinguish between pointers and references. 条款2:最好使用 C++ 转型操作符 012 Prefer C++-style casts. 条款3:绝对不要以多态(polymorphically)方式处理数组 016 Never treat arrays polymorphically. 条款4:非必要不提供 default constructor 019 Avoid gratuitous default constructors.
操作符(Operators) 024 条款5:对定制的“类型转换函数”保持警觉 024 Be wary of user-defined conversion functions. 条款6:区别 increment/decrement 操作符的 前置(prefix)和后置(postfix)形式 031 Distinguish between prefix and postfix forms of increment and decrement operators. 条款7:千万不要重载&&,||和, 操作符 035 Never overload &&, ||, or ,. 条款8:了解各种不同意义的 new 和 delete 038 Understand the different meanings of new and delete
异常(Exceptions) 044 条款9:利用 destructors 避免泄漏资源 045 Use destructors to prevent resource leaks. 条款10:在 constructors 内阻止资源泄漏(resource leak) 050 Prevent resource leaks in constructors. 条款11:禁止异常(exceptions)流出 destructors 之外 058 Prevent exceptions from leaving destructors. 条款12:了解“抛出一个 exception”与“传递一个参数” 或“调用一个虚函数”之间的差异 061 Understand how throwing an exception differs from passing a parameter or calling a virtual function. 条款13:以 by reference 方式捕捉 exceptions 068 Catch exceptions by reference. 条款14:明智运用 exception specifications 072 Use exception specifications judiciously. 条款15:了解异常处理(exception handling)的成本 078 Understand the costs of exception handling.

技术(Techniques, Idioms, Patterns) 123 条款25:将 constructor 和 non-member functions 虚化 123 Virtualizing constructors and non-member functions. 条款26:限制某个 class 所能产生的对象数量 130 Limiting the number of objects of a class. 条款27:要求(或禁止)对象产生于 heap 之中 145 Requiring or prohibiting heap-based objects. 条款28:Smart Pointers(智能指针) 159 条款29:Reference counting(引用计数) 183 条款30:Proxy classes(替身类、代理类) 213 条款31:让函数根据一个以上的对象类型来决定如何虚化 228 Making functions virtual with respect to more than one object.
杂项讨论(Miscellany) 252 条款32:在未来时态下发展程序 252 Program in the future tense. 条款33:将非尾端类(non-leaf classes)设计为 抽象类(abstract classes) 258 Make non-leaf classes abstract. 条款34:如何在同一个程序中结合 C++ 和 C 270 Understand how to combine C++ and C in the same program. 条款35:让自己习惯于标准 C++ 语言 277 Familiarize yourself with the language standard. 推荐读物 285 auto_ptr 实现代码 291 索引(一)(General Index) 295 索引(二)(Index of Example Classes,Functions,and Templtes) 313 |
