Avoiding multiple objects of same name in C++


Avoiding multiple objects of same name in C++

I think the issue was by ths following , There is no discernible problem with your code nor will there be any issue with multiple objects. The variable p has automatic storage duration and is destroyed when it goes out of scope. When this means is that at the end of each iteration of the for loop p is destroyed and no longer exists.

Avoiding many nested callbacks when animating multiple objects

around this issue For a version that's easier to read and maintain, you can use the jquery-fxQueues plugin which overloads the $.animate() function to support global animation queues. This means that your code can be written simply as:
code :
function animation() {
    var o2 = $(".img2", obj),
        o3 = $(".img3", obj),
        o4 = $(".img4", obj);
    o2.animate({opacity: "1"}, {duration:s, queue: "global", postDelay:p});
    o3.animate({opacity: "1"}, {duration:s, queue: "global"});
    o2.animate({opacity: "0"}, {duration:0, queue: "global", postDelay:p});
    o4.animate({opacity: "1"}, {duration:s, queue: "global"});
    o3.animate({opacity: "0"}, {duration:0, queue: "global", postDelay:p});
    o4.animate({opacity: "0"}, {duration:s, queue: "global", postDelay:p, 
                                complete:animation}); // repeat when done
}
/* functions to emulate a global queue */
var Q = $({}); // empty object to store global queue
var enQ = function(func) { Q.queue("global", func); } // add to queue
var deQ = function() { Q.dequeue("global"); }  // pop next animate
var stopQ = function() { Q.clearQueue("global"); }  // clear animation

function animate() {
    enQ(function() {
        o2.animate({opacity: "1"}, s, e, deQ);
    });
    enQ(function() {
        o3.delay(p).animate({opacity: "1"}, s, e, deQ);
    });
    enQ(function() {
        o2.css("opacity", "0");
        o4.delay(p).animate({opacity: "1"}, s, e, deQ);
    });
    enQ(function() {
        o3.css("opacity", "0");
        o4.delay(p).animate({opacity: "0"}, s, e, deQ);
    });
    enQ(function() {
        o3.css("opacity", "0");
        o4.delay(p).animate({opacity: "0"}, s, e, deQ);
    });
    enQ(animate); // repeat when done
    deQ();  // start the animation by dequeueing an entry

Does that help Redis can provide major benefits to your application's infrastructure, but I've found that, due to the specific operations you can perform on the various data types, you really need to put some thought ahead of time into how you're going to access your data. In this example, if you are very often iterating over a bunch of conferences and outputting the attendees, and are not otherwise benefiting from Redis' ability to do rich set operations (such as intersections, unions, etc.), maybe it's not a good fit for that data model.
On the other hand, if you are benefiting from Redis in performance-intensive parts of your application, it may be worth eating the occasional N+1 GET on Redis in order to reap those benefits. You have to do profiling on the parts of the app that you care about to see if the tradeoffs are worth it.

They all share the same private variables, with different values.
code :
public interface IGraph
{
    // TODO: Consider making this read-only in the interface...
    public string ImageFile { get; set; }
}
List<IGraph> listOfGraphs = new List<IGraph>();
listOfGraphs.Add(new GraphOne());
listOfGraphs.Add(new GraphTwo());
listOfGraphs.Add(new GraphThree());

foreach (IGraph currentGraph in listOfGraphs)
{
   string imageFile = currentGraph.ImageFile;
}

I wish this helpful for you Your problem is very amenable to OOP-style design. You can use reference classes or S4 to export a single global, e.g., a MapAnalysis class generator. The idea is then that someone creates this using
code :
 ma <- new('MapAnalysis', option1 = ..., option2 = ..., ...) # S4
 # or
 ma <- MapAnalysis$new(option1 = ..., ...) # refClass
 ma$loadData(...)
 ma$setParameters(...)

this one helps. So based on the conversation in chat, the refactoring is as follows:
