どうやら ;-) 標準コンテナは何らかの形の保証を提供します。
どのような種類の保証があり、コンテナの種類によってどのような違いがあるのでしょうか?
勤務地SGIページ(について言語) 私はこれを思いつきました:
Container Types:
================
Container:
Forward Container
Reverse Container
Random Access Container
Sequence
Front Insert Sequence
Back Insert Sequence
Associative Container
Simple Associative Container
Pair Associative Container
Sorted Associative Container
Multiple Associative Container
Container Types mapped to Standard Containers
=============================================
std::vector: Sequence Back Sequence Forward/Reverse/Random Container
std::deque: Sequence Front/Back Sequence Forward/Reverse/Random Container
std::list: Sequence Front/Back Sequence Forward/Reverse Container
std::set: Sorted/Simple/Unique Associative Container Forward Container
std::map: Sorted/Pair/Unique Associative Container Forward Container
std::multiset: Sorted/Simple/Multiple Associative Container Forward Container
std::multimap: Sorted/Pair/Multiple Associative Container Forward Container
Container Guarantees:
=====================

vector<T> v; Make an empty vector. O(1)
vector<T> v(n); Make a vector with N elements. O(n)
vector<T> v(n, value); Make a vector with N elements, initialized to value. O(n)
vector<T> v(begin, end); Make a vector and copy the elements from begin to end. O(n)
アクセサ
v[i] Return (or set) the I'th element. O(1)
v.at(i) Return (or set) the I'th element, with bounds checking. O(1)
v.size() Return current number of elements. O(1)
v.empty() Return true if vector is empty. O(1)
v.begin() Return random access iterator to start. O(1)
v.end() Return random access iterator to end. O(1)
v.front() Return the first element. O(1)
v.back() Return the last element. O(1)
v.capacity() Return maximum number of elements. O(1)
修飾子
v.push_back(value) Add value to end. O(1) (amortized)
v.insert(iterator, value) Insert value at the position indexed by iterator. O(n)
v.pop_back() Remove value from end. O(1)
v.assign(begin, end) Clear the container and copy in the elements from begin to end. O(n)
v.erase(iterator) Erase value indexed by iterator. O(n)
v.erase(begin, end) Erase the elements from begin to end. O(n)
