Aucun élément n'est copié. Le other récipient est vide après l'opération. La fonction ne fait rien si this == &other. Si get_allocator() != other.get_allocator(), le comportement est indéfini. Pas itérateurs ou les références deviennent invalidé, sauf que les itérateurs d'éléments déplacés maintenant se référer à *this, pas dans other. La première version utilise operator< de comparer les éléments, la deuxième version utilise la fonction de comparaison donnée comp .

Original:

No elements are copied. The container other becomes empty after the operation. The function does nothing if this == &other. If get_allocator() != other.get_allocator(), the behavior is undefined. No iterators or references become invalidated, except that the iterators of moved elements now refer into *this, not into other. The first version uses operator< to compare the elements, the second version uses the given comparison function comp.

other	-	un autre récipient de fusion Original: another container to merge The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.
comp	-	comparison function which returns ​true if the first argument is less than the second. The signature of the comparison function should be equivalent to the following: bool cmp(const Type1 &a, const Type2 &b); The signature does not need to have const &, but the function must not modify the objects passed to it. The types Type1 and Type2 must be such that an object of type list<T,Allocator>::const_iterator can be dereferenced and then implicitly converted to both of them. ​

Exemple

#include <iostream>
#include <list>
 
std::ostream& operator<<(std::ostream& ostr, const std::list<int>& list)
{
    for (auto &i : list) {
        ostr << " " << i;
    }
    return ostr;
}
 
int main()
{
    std::list<int> list1 = { 5,9,0,1,3 };
    std::list<int> list2 = { 8,7,2,6,4 };
 
    list1.sort();
    list2.sort();
    std::cout << "list1:  " << list1 << "\n";
    std::cout << "list2:  " << list2 << "\n";
    list1.merge(list2);
