This was answered by an official Swift developer (Slava_Pestov) on the Swift forums. Here is the summary: You should use AnyObject (protocol SomeProtocol: AnyObject). AnyObject and class are equivalent. There is no difference. class will eventually be deprecated.
In R every “object” has a mode and a class. The former represents how an object is stored in memory (numeric, character, list and function) while the later represents its abstract type. For example: d <- data.frame(V1=c(1,2)) class(d) # [1] “data.frame” mode(d) # [1] “list” typeof(d) # list As you can see data frames are … Read more
You can use setattr (be careful though: not every string is a valid attribute name!): >>> class AllMyFields: … def __init__(self, dictionary): … for k, v in dictionary.items(): … setattr(self, k, v) … >>> o = AllMyFields({‘a’: 1, ‘b’: 2}) >>> o.a 1 Edit: let me explain the difference between the above code and SilentGhost’s … Read more
This is Rule 1 of the “Initializer Chaining” rules as specified in the Swift Programming Guide, which reads: Rule 1: Designated initializers must call a designated initializer from their immediate superclass. https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/Initialization.html Emphasis mine. Designated initializers cannot call convenience initializers. There is a diagram that goes along with the rules to demonstrate what initializer “directions” … Read more
I use GenMyModel, first released in 2013. It’s a real UML modeler, not a drawing tool. Your diagrams are UML-compliant, generate code and can be exported as UML/XMI files. It’s web-based and free so it matches your criteria.
Multiple classes can be assigned to a div. Just separate them in the class name with spaces like this: <div class=”rule1 rule2 rule3″>Content</div> This div will then match any style rules for three different class selectors: .rule1, .rule2 and .rule3. CSS rules are applied to objects in the page that match their selectors in the … Read more
They are access modifiers and help us implement Encapsulation (or information hiding). They tell the compiler which other classes should have access to the field or method being defined. private – Only the current class will have access to the field or method. protected – Only the current class and subclasses (and sometimes also same-package … Read more
Edit: This question was answered in 2016 and is kind of outdated. Look at @Nenad up-to-date answer below. Solution from typescript interfaces reference: interface ClockConstructor { new (hour: number, minute: number): ClockInterface; } interface ClockInterface { tick(); } function createClock(ctor: ClockConstructor, hour: number, minute: number): ClockInterface { return new ctor(hour, minute); } class DigitalClock implements … Read more
Create a function. Functions do specific things, classes are specific things. Classes often have methods, which are functions that are associated with a particular class, and do things associated with the thing that the class is – but if all you want is to do something, a function is all you need. Essentially, a class … Read more
Disabling content filtering The easiest solution is going to the config.js and setting: config.allowedContent = true; (Remember to clear browser’s cache). Then CKEditor stops filtering the inputted content at all. However, this will totally disable content filtering which is one of the most important CKEditor features. Configuring content filtering You can also configure CKEditor’s content … Read more
