chaining

I got some text views and I want to make the buzz effect of MSN. My plan is: take the view, let say 10dip to the left, take it back to its start position after that take it 10dip up then back down back left... and so on. My point is, I have some sequence of movements that I want to set to one view and that needs to execute one after another. How can I do that? Snicolas Use an AnimationSet : AnimationSet set = new AnimationSet(true); Animation animation = new AlphaAnimation(0.0f, 1.0f); animation.setDuration(100); set.addAnimation(animation); animation = new TranslateAnimation( Animation

I know that not all jQuery functions can be chained together. Is there a rule of thumb on this. When can we not chain 2 functions together. You can chain when the function returns a "jQuery object". For example, .css(property, value) can be chained, as the doc says it Returns jQuery: while .height() cannot , because it returns an integer. Typically, the functions that returns "jQuery objects" are those which typically would not "return a value", e.g. setter methods ( .css(prop, val) , .addClass() ), event binders ( .click(handler) ), etc. (Of course traverse methods ( .parent() , .find() , etc

I have this code: $("#test").siblings('p').remove(); $("#test").remove(); How can I chain this code instead of writing it separately? Eli You want to use addBack() in this case: $("#test").siblings('p').addBack().remove(); EDIT Firstly, for future visitors, if you're using jQuery version 1.8-, you're probably need to use andSelf() which is the predecessor of addBack() for compatibility issues. Secondly, both end and addBack will do the same task in this case but they're actually different perspective. Take a look at this HTML: <div class="grandpa"> <div class="dad"> <div class="son"> Test <

While answering a few questions on here earlier and from some work I have been doing lately I have been wondering why Java does not support method chaining on its built in classes. If I were to create a Car class for example, I could make it chainable by reutrning this instead of void as follows: public class Car { private String make; public Car setMake(String make) { this.make = make; return this; } } Is there any particular reason why the built in libraries don't tend to do things this way? Is there a downside to method chaining? I may have overlooked something which would explain the lack

When I reading this answer , find var g = f.call.bind(f); . I can't understand this with my first sight. So does it has some direct meaning, and has some appropriate usage scenarios? And further when you using call(or apply) or bind or both in chaining, what will happen? Is there some laws? Bergi var g = f.call.bind(f); . I can't understand this with my first sight. I assume you're familar with both the .call() and .bind() Function methods? Well, it binds the f.call method to the function f . Notice that f.call is just Function.prototype.call , it doesn't matter that we access it as a property

Promise.all() doesn't guarantee that promises will be resolved in order. How can this be done? Benjamin Gruenbaum Since you're using Bluebird JS, this can be actually done in a simple way. In version 2.0, Bluebird introduced the Promise.each method that does this, for looping a then is simple enough, but since it is so common and got requested time after time eventually it was added as its own method. function foo(item, ms){ // note bluebird has a delay method return Promise.delay(ms, item).then(console.log.bind(console)) } var items = ['one', 'two', 'three']; Promise.each(items, function(item

I have a service called paymentStrategy that get injected in my controller. $scope.buy = function() { paymentStrategy.buy() .then(function(response) { } } This buy method from paymentStrategy triggers several methods that needs to be called sequentially. When all the methods within buy() are done, then() needs to be called. It is probably trivial but I am quite new to angular. At the moment, buy().then() gets triggered straight after the init() methods. I have the feeling we need to put all theses methods in a array of promises and apply $q.all(). Any help or suggestion would be greatly
