boilerplate

I implement equals() the Java 7 way: @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; MyClass other = (MyClass) obj; return Objects.equal(myFirstField, other.myFirstField) && Objects.equal(mySecondField, other.mySecondField); } Is there a way to reduce the code duplication? I would prefer something like @Override public boolean equals(Object obj) { if (Objects.equalsEarlyExit(this, obj)) return Objects.equalstEarlyExitResult(this, obj); MyClass other = (MyClass) obj; return Objects.equal

I run into this situation often enough for it to be annoying. Let's say I have a sum type which can hold an instance of x or a bunch of other things unrelated to x - data Foo x = X x | Y Int | Z String | ...(other constructors not involving x) To declare a Functor instance I have to do this - instance Functor Foo where fmap f (X x) = X (f x) fmap _ (Y y) = Y y fmap _ (Z z) = Z z ... And so on Whereas what I would like to do is this - instance Functor Foo where fmap f (X x) = X (f x) fmap _ a = a i.e. I only care about the X constructor, all other constructors are simply "passed through". But

I'm trying to remove some boilerplate from routes in Camel. For example, let's consider the two routes, which are similar and most of their inner stuff could be generated. I've created a component "template", which creates TemplateEndpoint , and modifyed an XML config to use the template component. A custom method TemplateEndpoint.generateRoute (adding route definitions) is being called from StartupListener (defined in TemplateEndpoint.setSuffix ). So while Camel context starting, route definitions appear in the context, but the framework doesn't create route services for them and hence they

I'm coming up with performance goals for the new year, and I thought I'd be fun to put a goal to reduce the size of the code base, especially boilerplate. One action I've come up with to address this is to use Project Lombok to make beans as short as they should be. But I have a habit of overlooking downsides to new software and approaches, so I'm relying on the Stack Overflow community: Can anyone tell me why Lombok is a bad idea? Zeki A major downside is IDE support. Since Lombok is not actually a language change, and since your IDE only understands java, you will need an IDE that supports

I'm working on a Web Progressive App using Angular 4. This app needs to be wrapped up in an Apache Cordova as a Hybrid app built for Android and iOS platforms. I'm looking for a working boilerplate template for Cordova + Angular 4. Cordova is using www folder for web app and Angular 4 is using src folder for web app. How to merge this two together to work? Angular 'ng serve' should also work? I finally manage to solve my problem. We need to merge Cordova "www" folder and angular "src" folder in one "src" folder where angular app should be. package.json needs to be merged as well to fit for

I think I'm misunderstanding the concept of the .clearfix class. Maybe somebody can help me out. I'm looking for a way to use float and clear without messing up my markup. So I thought, that's where .clearfix can be used for. Inside of an empty H5BP-project, my markup looks like: <div></div> <div></div> <div class="clearfix"></div> <div></div> <div></div> <div class="clearfix"></div> <div></div> <div></div> <div class="clearfix"></div> Below the result. I was expecting a tic tac toe-field, though. Can somebody tell me: How I can achieve my goal and What the .clearfix class really can be used
