The latest version of this topic can be found at list::swap (STL/CLR).

Swaps the contents of two containers.

Syntax

void swap(list<Value>% right);

Parameters

right
Container to swap contents with.

Remarks

The member function swaps the controlled sequences between *this and right. It does so in constant time and it throws no exceptions. You use it as a quick way to exchange the contents of two containers.

Example

// cliext_list_swap.cpp   
// compile with: /clr   
#include <cliext/list>   
  
int main()   
    {   
    cliext::list<wchar_t> c1;   
    c1.push_back(L'a');   
    c1.push_back(L'b');   
    c1.push_back(L'c');   
  
// display initial contents " a b c"   
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// construct another container with repetition of values   
    cliext::list<wchar_t> c2(5, L'x');   
    for each (wchar_t elem in c2)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// swap and redisplay   
    c1.swap(c2);   
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
    for each (wchar_t elem in c2)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
    return (0);   
    }
