lua - Converting decimal number to flag values -


I have some constraints, such as: 

  hit = 0x1 = 0x2 remote_interested = 0x4 Remote_choose = 0x8 support_extensions = 0x10 local_connection = 0x20 handshake = 0x40 connecting = 0x80 queue = 0x100 on_parole = 0x200 seed = 0x400 optimist_choc = 0x800 rc4_encrypted = 0x100000 plain-text-encrypted = 0x200000

And the document tells me 'The flag characteristic tells you which state the peers are inside. It is set up for any combination of above ' so basically I call dll and it fills in decimal with the decimal number that represents the flag in the structure, some examples: 

  2086227 170 2098227 106

How do I set flags from decimals?

To determine which flags were set, you need to perform operations (in Lua 5.2) Need to use. For example: 

  is the function haslags (int, ...) local all = bit32.bor (...) return bit32.band (int, all) == if all the end is flags (2086227, interesting, local_connection) - Do something interesting and local_connection end

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket? SupportForm supportForm: form [supportTicket] = form (mapping ("question" -> text, "priority" -> text) (apply support ticket. (HelpText.update) What are the good practices here? What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....
