What would be the implementation of the function in this scenario

help you fix your problem You can pass in a function reference as a third argument and use it to calculate the result using the first two arguments:
code :
function add(a, b){return a + b}
function mul(a, b){return a * b}

function wrapper(a, b, callback){
  return callback(a, b);
}


console.log(wrapper(4, 5, add))
console.log(wrapper(4, 5, mul))
//mapping of action name to logic that will be executed
var actionLookupTable = {
  "addition": add,
  "multiplication": mul
}

function defaultAction() { /* a no-op */}

function add(a, b){return a + b}
function mul(a, b){return a * b}

function wrapper(a, b, actionName){
  //fetch the logic to execute for the action. 
  //If the action name is not recognised, use a default one otherwise you will get an error
  var logic = actionLookupTable[actionName] || defaultAction;
  return logic(a, b);
}


console.log(wrapper(4, 5, "addition"));
console.log(wrapper(4, 5, "multiplication"));
console.log(wrapper(4, 5, "division")); //no implementation but no error is raised

seems to work fine When you press button 1, you can call X using BackgroundWorker to run it in a separate thread. Then set a variable (or grey out Button 1) such that the user cannot run X again.
X can write to its own collection while it processes the DB. Then it can replace an instance variable with this collection. By only doing a single replacement you can avoid synchronization problems between X and the UI thread.

hop of those help? Yes, that can be easily accomplished with WCF and WIF. You only need an STS implemenation or service, with three WCF endpoints. One endpoint for net.tcp with Windows authentication, one endpoint for authenticating with certificates (this could be message security with X509 client credential or Http transport security wiht X509 credential), and another endpoint for username and password. You might want to look at the STS Starter kit from Dominick Baier, I think he already provided an implementation for that in that project.
It's a matter of exposing the STS service with two endpoints as follow,

like below fixes the issue First I would recommend the book called "Lucene In Action" It is for Java, but it is on Lucene version 3.0.3, which happens to be the current Lucene.NET version..the API is the same so its a great starting resource.
To answer... 1) Is it possible to only show authorized records in Lucene.NET? Yes..you can do it several ways. You can seperate the indexes if you need to by user OR you can add additional fields and always include those in the search queries.

Is there a scenario where Java7's Hashmap implementation is preferred to Java8's implementation

Is there a scenario where Java7's Hashmap implementation is preferred to Java8's implementation

like below fixes the issue Java8 will use balanced tree in number of entries in the bucket in > N, where N is chosen empirically, and use list once again if that number is < K. I'd expect worse performance if number of entries in bucket changes in way that "treefyng / untreeifying" happens often. That might happen due to specific hash function.
Also I'm not sure if overhead for creating and querying tree is worth the profit for small N.
