vector::clear (STL/CLR)

Supprime tous les éléments.

    void clear();

Notes

La fonction membre appelle efficacement vector::erase (STL/CLR)(vector::begin (STL/CLR)(),vector::end (STL/CLR)()).Vous l'utilisez pour garantir que la séquence contrôlée est vide.

Exemple

// cliext_vector_clear.cpp 
// compile with: /clr 
#include <cliext/vector> 
 
int main() 
    { 
    cliext::vector<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(); 
 
// clear the container and reinspect 
    c1.clear(); 
    System::Console::WriteLine("size() = {0}", c1.size()); 
 
// add elements and clear again 
    c1.push_back(L'a'); 
    c1.push_back(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); 
    }
