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);
}
a b b b c
a b b b c
b b b
