class - Calling a Lua function from within an object instance -

-

"itemprop =" text ">

I think that creates a scene and within the visual function it creates a deck object and a function is wonGame A main lua file () that checks the play when the game has won 

  local musician = ("composer") function view:. "Deck" myDeck = deck: New () function wonGame () print ("You have won the game") and end   
 My question - I need deck class How can I call the function () within the file? For example, I have a function deck class  
  function checkCondition (e) if (somethingTrue) wonGame () --This main file should be the end function at the end    
 
 
 You can always try and apply a representative to ex:  
 Basically this means you have a property in the 'deck' which combines back into 'view' when you make your deck you will decide something like <
  Deck.SceneDelegate = self   
 Then you can just say in the deck  
  View the scene. Von game ()

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
