hash_multimap::swap (STL/CLR)
Swaps the contents of two containers.
void swap(hash_multimap<Key, Mapped>% 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_hash_multimap_swap.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_multimap<wchar_t, int> Myhash_multimap;
int main()
{
Myhash_multimap c1;
c1.insert(Myhash_multimap::make_value(L'a', 1));
c1.insert(Myhash_multimap::make_value(L'b', 2));
c1.insert(Myhash_multimap::make_value(L'c', 3));
// display contents " [a 1] [b 2] [c 3]"
for each (Myhash_multimap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
// construct another container with repetition of values
Myhash_multimap c2;
c2.insert(Myhash_multimap::make_value(L'd', 4));
c2.insert(Myhash_multimap::make_value(L'e', 5));
c2.insert(Myhash_multimap::make_value(L'f', 6));
for each (Myhash_multimap::value_type elem in c2)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
// swap and redisplay
c1.swap(c2);
for each (Myhash_multimap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
for each (Myhash_multimap::value_type elem in c2)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
return (0);
}
