multiset::clear (STL/CLR)

Removes all elements.

    void clear();

Remarks

The member function effectively calls multiset::erase (STL/CLR)( multiset::begin (STL/CLR)(), multiset::end (STL/CLR)()). You use it to ensure that the controlled sequence is empty.

Example

// cliext_multiset_clear.cpp 
// compile with: /clr 
#include <cliext/set> 
 
typedef cliext::multiset<wchar_t> Mymultiset; 
int main() 
    { 
    Mymultiset c1; 
    c1.insert(L'a'); 
    c1.insert(L'b'); 
    c1.insert(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// clear the container and reinspect 
    c1.clear(); 
    System::Console::WriteLine("size() = {0}", c1.size()); 
 
// add elements and clear again 
    c1.insert(L'a'); 
    c1.insert(L'b'); 
 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    c1.clear(); 
    System::Console::WriteLine("size() = {0}", c1.size()); 
    return (0); 
    } 
 
 a b c
size() = 0
 a b
size() = 0
