list::remove_if (STL/CLR)

Removes elements that pass a specified test.

    template<typename Pred1>
        void remove_if(Pred1 pred);

Parameters

• pred
  Test for elements to remove.

Remarks

The member function removes from the controlled sequence (erases) every element X for which pred(X) is true. You use it to remove all elements that satisfy a condition you specify as a function or delegate.

Example

// cliext_list_remove_if.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'b'); 
    c1.push_back(L'b'); 
    c1.push_back(L'c'); 
 
// display initial contents " a b b b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// fail to remove and redisplay 
    c1.remove_if(cliext::binder2nd<cliext::equal_to<wchar_t> >( 
        cliext::equal_to<wchar_t>(), L'd')); 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// remove and redisplay 
    c1.remove_if(cliext::binder2nd<cliext::not_equal_to<wchar_t> >( 
        cliext::not_equal_to<wchar_t>(), L'b')); 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
