Enum.HasFlag, why no Enum.SetFlag?
Why isn’t there an Enum.SetFlag like there is an Enum.HasFlag?

Added the answer that antonyt provided: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if ((getIntent().getFlags() & Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT) != 0) { // Activity was brought to front and not created, // Thus finishing this will get us to the last viewed activity finish(); return; } // Regular activity creation code… }
How to disable a log.Logger
No reason to create your own type for a common io.Writer when one exists in the io/ioutil package. import ( “log” “io/ioutil” ) func init() { log.SetOutput(ioutil.Discard) }
Switch on Enum (with Flags attribute) without declaring every possible combination?
How about this. Of course the arguments and return types of DoSomething, etc., can be anything you like. class Program { [Flags] public enum CheckType { Form = 1, QueryString = 2, TempData = 4, } private static bool DoSomething(IEnumerable cln) { Console.WriteLine(“DoSomething”); return true; } private static bool DoSomethingElse(IEnumerable cln) { Console.WriteLine(“DoSomethingElse”); return true; … Read more
Material design layout_scrollFlags meanings
