This is what the equals method does: public boolean equals(Object obj) { if (obj instanceof Integer) { return value == ((Integer)obj).intValue(); } return false; } As you can see, there’s no hash code calculation, but there are a few other operations taking place there. Although x.intValue() == y.intValue() might be slightly faster, you’re getting into … Read more
Have you looked at Primus? It offers the cookie requirements you mention, it supports all of the major ‘real-time’/websocket libraries available and is a pretty active project. To me it also sounds like vendor lock-in could be a concern for you and Primus would address that. The fact that it uses a plugin system should … Read more
I have tried using, both and I’d definitely recommend Gradle. While both of them have pretty much the same expressiveness, I found Gradle to be much more stable (since version 1.0), less effort to install, and better documented. Although Buildr is undoubtedly a great effort, at the moment Gradle is much more professionally made. The … Read more
I usally use the TimeSpan.FromXXX methods to do something like this: if((myDate – myOtherDate) > TimeSpan.FromSeconds(10)) { //Do something here }
As you suspect, you’re returning the match of the first property seen. You should return false if that property doesn’t match, but keep looking otherwise. Also, return false if there’s no prop property found on y (that is, the counts match, but not the actual properties). If all properties have matched, return true: var deepEqual … Read more
The easy way The simplest approach is to write a member function wrapper called in() around std::find with a pair of iterators to look for the data in question. I wrote a simple template<class It> in(It first, It last) member function for that template<class It> bool in(It first, It last) const { return std::find(first, last, … Read more
How can I tell the difference between an object literal and any other Javascript object (e.g. a DOM node, a Date object, etc.)? The short answer is you can’t. An object literal is something like: var objLiteral = {foo: ‘foo’, bar: ‘bar’}; whereas the same object created using the Object constructor might be: var obj … Read more
in C (and other languages probably) a single | or & is a bitwise comparison. The double || or && is a logical comparison. Edit: Be sure to read Mehrdad’s comment below regarding “without short-circuiting” In practice, since true is often equivalent to 1 and false is often equivalent to 0, the bitwise comparisons can … Read more
It can be do in two way :- 1. First way inside xml :- android:textColor=”@{notice.action.equals(`continue`) ? @color/enabledPurple : @color/disabledGray }” 2. Second way (programatically) Inside xml :- app:setColor=”@{notice.action}” inside activity or custom class : – @BindingAdapter(“setColor”) public static void setTextColor(TextView textView, String s) { Context context = textView.getContext(); textView.setTextColor(s.equals(“continue”) ? context.getResources().getColor(R.color.enabledPurple) : context.getResources().getColor(R.color.disabledGray)); }
