STL高效编程：英文版 内容简介

本书以英文版的形式介绍了STL高效编程。

STL高效编程：英文版 本书特色

50条有效使用STL的经验这是Effective C++的第3卷，还是那么出色。——Herb Sutter, ISO/ANSI C++标准委员会主席所有的C++程序员都必读的书少之又少，而本书就是其中的一本。C++的标准模板库 (STL) 是革命性的，但是要想学会用好STL却充满了挑战性。中国台湾技术作家侯捷先生曾经把STL的学习过程比喻为三个境界：**境界：熟用STL。第二境界：了解泛型技术的内涵与STL的学理乃至实作。第三境界：扩充STL。本书无疑是你达到第二境界的*佳读本。在本书中，C++技术权威Scott Meyers揭示了专家总结的一些关键规则，包括他们总是采用的做法以及总是避免的做法。这些规则可以发挥STL的*大效用。有些书只是描述STL中有些什么内容，而本书则讲述如何使用STL。本书共有50条指导原则，在讲述每一条指导原则时，Scott Meyers都提供了透彻的分析和深刻的实例，所以读者不仅可以学到要做什么，而且还能够知道什么时候该这样做，以及为什么要这样做。如同Meyers的其他著作一样，本书充满了从实践中总结出来的智慧。清晰、简明、透彻的风格使本书成为每一位STL程序员的案头**。关于选择容器的建议，涉及的容器有：标准STL容器（例如vector和list） 、非标准的STL容器 （例如hash_set和hash_map） ，以及非STL容器 (例如bitset) 。一些提高效率的技术，通过它们可以*大程度地提高STL （以及使用STL的程序） 的效率。

Chapter 1: Containers
Item 1: Choose your containers with care.
Item 2: Beware the illusion of container-independent code.
Item 3: Make copying cheap and correct for objects in containers.
Item 4: Call empty instead of checking size() against zero.
Item 5: Prefer range member functions to their single-element counterparts.
Item 6: Be alert for C++’s most vexing parse.
Item 7: When using containers of newed pointers, remember to delete the pointers before the container is destroyed.
Item 8: Never create containers of auto_ptrs.
Item 9: Choose carefully among erasing options.
Item 10: Be aware of allocator conventions and restrictions.

Item 12: Have realistic expectations about the thread safety of STL containers.
Chapter 2: vector and string
Item 13: Prefer vector and string to dynamically allocated arrays.
Item 14: Use reserve to avoid unnecessary reallocations.
Item 15: Be aware of variations in string implementations.
Item 16: Know how to pass vector and string data to legacy APIs.
Item 17: Use “the swap trick” to trim excess capacity.
Item 18: Avoid using vector.
Chapter 3: Associative Containers
Item 19: Understand the difference between equality and equivalence.
Item 20: Specify comparison types for associative containers of pointers.
Item 21: Always have comparison functions return false for equal values.
Item 22: Avoid in-place key modification in set and multiset.
Item 23: Consider replacing associative containers with sorted vectors.
Item 24: Choose carefully between map::operator[] and map::insert when efficiency is important.
Item 25: Familiarize yourself with the nonstandard hashed containers.
Chapter 4: Iterators
Item 26: Prefer iterator to const_iterator, reverse_iterator, and const_reverse_iterator.
Item 27: Use distance and advance to convert const_iterators to iterators.
Item 28: Understand how to use a reverse_iterator’s base iterator.
Item 29: Consider istreambuf_iterators for character by character input.
Chapter 5: Algorithms
Item 30: Make sure destination ranges are big enough.
Item 31: Know your sorting options.
Item 32: Follow remove-like algorithms by erase if you really want to remove something.
Item 33: Be wary of remove-like algorithms on containers of pointers.
Item 34: Note which algorithms expect sorted ranges.
Item 35: Implement simple case-insensitive string comparisons via mismatch or lexicographical_compare.
Item 36: Understand the proper implementation of copy_if.
Item 37: Use accumulate or for_each to summarize ranges.
Chapter 6: Functors, Functor Classes, Functions, etc.
Item 38: Design functor classes for pass-by-value.
Item 39: Make predicates pure functions.
Item 40: Make functor classes adaptable.
Item 41: Understand the reasons for ptr_fun, mem_fun, and mem_fun_ref.
Item 42: Make sure less means operator<.
Chapter 7: Programming with the STL
Item 43: Prefer algorithm calls to hand-written loops.
Item 44: Prefer member functions to algorithms with the same names.
Item 45: Distinguish among count, find, binary_search, lower_bound, upper_bound, and equal_range.
Item 46: Consider function objects instead of functions as algorithm parameters.
Item 47: Avoid producing write-only code.
Item 48: Always #include the proper headers.
Item 49: Learn to decipher STL-related compiler diagnostics.
Item 50: Familiarize yourself with STL-related web sites.
