hash_multimap::clear (STL/CLR)

Odebere všechny prvky.

    void clear();

Poznámky

The member function effectively calls hash_multimap::erase (STL/CLR)( hash_multimap::begin (STL/CLR)(), hash_multimap::end (STL/CLR)()).Slouží k zajištění, že řízené sekvence je prázdná.

Příklad

// cliext_hash_multimap_clear.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(); 
 
// clear the container and reinspect 
    c1.clear(); 
    System::Console::WriteLine("size() = {0}", c1.size()); 
 
    c1.insert(Myhash_multimap::make_value(L'a', 1)); 
    c1.insert(Myhash_multimap::make_value(L'b', 2)); 
 
// display contents " [a 1] [b 2]" 
    for each (Myhash_multimap::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
    c1.clear(); 
    System::Console::WriteLine("size() = {0}", c1.size()); 
    return (0); 
    }
