Effective C++ 改善程序与设计的55个具体做法

  • 1 让自己习惯C++(Accustoming Yourself to C++)
    • 条款01: 视C++为一个语言联邦(View C++ as a federation of languages)
    • 条款02:尽量以const,enum,inline替换#define(Prefer consts,enums,and inlines to #defines)
    • 条款03:尽可能使用const(Use const whenever possible)
    • 条款04:确定对象被使用前已先被初始化(Make sure that objects are initalized before they're used)
  • 2 构造/析构/赋值运算(Constructors,Destructors,and Assignment Operators)
    • 条款05:了解C++默默编写并调用哪些函数(Know what functions C++ silently writes and calls)
    • 条款06:若不想使用编译器自动生成的函数,就该明确拒绝(Explicitly disallow the use of complier-generated functions you do not want.)
    • 条款07: 为多态基类声明virtual析构函数(Declare destructors virtual in polymorphic base classes.)
    • 条款08:别让异常逃离析构函数(Prevent exceptions from leaving destructors.)
    • 条款09:绝不在构造和析构过程中调用virtual函数(Never call virtual functions during construction or destruction.)
    • 条款10:令operator= 返回一个reference to *this(Have assignment operators return a reference to *this.)
    • 条款11:在operator=中处理“自我赋值”(Handle assignment to selft in operator=.)
    • 条款12:复制对象时勿忘其每个成分(Copy all parts of an object.)
  • 3 资源管理(Resource Management)
    • 条款13:以对象管理资源(Use objects to manage resources)
    • 条款14:在资源管理类中小心copying行为(Think carefully about copying behavior in resource-managing classes.)
    • 条款15:在资源管理类中提供对原始资源的访问(Provide access to raw resources in resource-managing classes.)
    • 条款16:成对使用new和delete时要采取相同形式(Use the same form in corresponding uses of new and delete.)
    • 条款17:以独立语句将newed对象置入智能指针(Store newed objects in smart points in standalone statements.)
  • 4 设计与声明(Designs and Declarations.)
    • 条款18:让接口容易被正确使用,不易被误用(Make interfaces easy to use correctly and hard to use incorrectly.)
    • 条款19:设计class犹如设计type (Treat class design as type design.)
    • 条款20:宁以pass-by-reference-to-const替换pass-by-value(Prefer pass-by-reference-to-const to pass-by-value.)
    • 条款21:必须返回对象时,别妄想返回其reference(Don't try to return a reference when you must return an object.)
    • 条款22:将成员变量声明为private(Declare data members private.)
    • 条款23:宁以non-member、non-friend替换member函数(Prefer non-member non-friend functions to member functions.)
    • 条款24:若所有参数皆需要类型转换,请为此采用non-member函数(Declare non-member functions when type conversions should apply to all parameters.)
    • 条款25:考虑写出一个不抛异常的swap函数(Consider support for an non-throwing swap.)
  • 5 实现(Implementations)
    • 条款26:尽可能延后变量定义式的出现时间(Postpone variable definitions as long as possible.)
    • 条款27:尽量少做转型动作(Minimize casting.)
    • 条款28:避免返回handles指向对象内部成分(Avoid returning "handles" to object internals.)
    • 条款29:为“异常安全”而努力是值得的(Strive for exception-safe code.)
    • 条款30:透彻了解inlining的里里外外(Understand the ins and outs of inlining.)
    • 条款31:将文件间的编译依存关系将至最低(Minimize compilation dependencies between files.)
  • 6 继承与面向对象设计(Inheritance and Object-Oriented Design.)
    • 条款32:确定你的public继承塑模出is-a关系(Make sure public inheritance models "is-a".)
    • 条款33:避免遮掩继承而来的名称(Aviod hiding inherited names.)
    • 条款34:区分接口继承和实现继承(Differentiate between inheritance of interface and inheritance of implementation.)
    • 条款35:考虑virtual函数以外的其他选择(Consider alternatives to virtual functions.)
    • 条款36:绝不重新定义继承而来的non-virtual函数(Never redefine an inherited non-virtual function.)
    • 条款37:绝不重新定义继承而来的缺省参数值(Never redefine a function's inherited default parameter value.)
    • 条款38:通过复合塑模出has-a或“根据某物实现出”(Model "has-a" or "is-implemented-in-terms-of" through composition.)
    • 条款39:明智而审慎地使用private继承(Use private inheritance judiciously.)
    • 条款40:明智而审慎地使用多继承(Use multiple inheritance judiciously.)
  • 7 模板与泛型编程(Templates and Generic Programming)
    • 条款41:了解隐式接口和编译器多态(Understand implicit interface and complie-time polymorphism.)
    • 条款42:了解typename的双重意义(Understand the two meanings of typename.)
    • 条款43:学习处理模板化基类的名称(Know how to access names in templatized base classes.)
    • 条款44:将与参数无关的代码抽离templates(Factor parameter-independent code out of templates.)
    • 条款45:运用成员函数模板接受所有兼容类型(Use member function templates to accept "all cinplatible types".)
    • 条款46:需要类型转换时请为模板定义非成员函数(Define non-member functions inside templates when type conversions are desired.)
    • 条款47:请使用traits classes表现类型信息(Use traits classes for information about types.)
    • 条款48:认识template元编程(Be aware of template metaprogramming.)
  • 8 定制new和delete(Customizing new and delete)
    • 条款49:了解new-handler的行为(Understand the behavior of the new-handler.)
    • 条款50:了解new和delete的合理替换时间(Understand when it makes sense to replace new and delete.)
    • 条款51:编写new和delete时需要固守常规(Adhere to convention when writing new and delete.)
    • 条款52:写了placement new也要写placement delete(Write placement delete if you write placement new.)
  • 9 杂项讨论(Miscellany)
    • 条款53:不要轻易忽略编译器的警告(Pay attention to compiler warnings.)
    • 条款54:让自己熟悉包括TR1在内的标称程序库(Familiarize yourself with the stanard library,including TR1.)
    • 条款55:让自己熟悉Boost(Familiarize yourself with Boost.)
