Keine Elemente kopiert werden. Der Behälter other leer nach der Operation. Die Funktion tut nichts, wenn this ==&other. Wenn get_allocator()!= other.get_allocator(), ist das Verhalten undefiniert. Keine Iteratoren oder Referenzen geworden ungültig, außer dass die Iteratoren der bewegten Elemente nun in *this beziehen, nicht in other. Die erste Version verwendet operator< um die Elemente zu vergleichen, verwendet die zweite Version des gegebenen Vergleichsfunktion 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.

Parameter

other	-	ein weiterer Behälter zu verschmelzen 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. ​

Beispiel

#include <iostream>#include <list>   std::ostream& operator<<(std::ostream& ostr, conststd::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);std::cout<<"merged: "<< list1 <<"\n";}

Output:

list1: 0 1 3 5 9 list2: 2 4 6 7 8 merged: 0 1 2 3 4 5 6 7 8 9
