enumeration

Given the following two classes classdef EnumClass enumeration enumVal1 enumVal2 end end classdef EnumDisplay properties enumValue = EnumClass.enumVal1 numberValue = 1 end end When displaying an EnumClass , the value is displayed: >> E = EnumClass.enumVal1 E = enumVal1 but when displaying EnumDisplay in the command window, the enumeration value is suppressed, and only the array size and class are displayed. >> C = EnumDisplay() C = EnumDisplay with properties: enumValue: [1x1 EnumClass] numberValue: 1 What is the easiest way to have the enumeration value displayed in the class property list. I

Is there a way to enumerate the items in a list within mockito's thenReturn function so I return each item in a list. So far I've done this: List<Foo> returns = new ArrayList<Foo>(); //populate returns list Mockito.when( /* some function is called */ ).thenReturn(returns.get(0), returns.get(1), returns.get(2), returns.get(3)); This works exactly how I want it to. Each time the function is called, it returns a different object from the list, e.g get(1) , get(2) etc. But I want to simplify this and make it more dynamic to any size list in case I have a list with size say 100. I tried something

I noticed that List<T> defines its enumerator as a struct , while ArrayList defines its enumerator as a class . What's the difference? If I am to write an enumerator for my class, which one would be preferable? EDIT: My requirements cannot be fulfilled using yield , so I'm implementing an enumerator of my own. That said, I wonder whether it would be better to follow the lines of List<T> and implement it as a struct. Like this others, I would choose a class. Mutable structs are nasty. (And as Jared suggests, I'd use an iterator block. Hand-coding an enumerator is fiddly to get right.) See this

I am attempting to find a way to force Java to load/initialize an enumerated type (which is nested within a class that contains a static Map). This is important to me because the enumerated type has a constructor that populates said map, and without an explicit way to initialize this enum, the map will remain empty. I have attempted to use Class.forName , but this does not seem to work. I suppose I could create an instance of the enum (and store it in soem other collection or something), but I would like to know if there is an elegant way to do this. A class is loaded when you reference a

class Program { static void Main(string[] args) { var dictionary = new Dictionary<string, int>() { {"1", 1}, {"2", 2}, {"3", 3} }; foreach (var s in dictionary.Keys) { // Throws the "Collection was modified exception..." on the next iteration // What's up with that? dictionary[s] = 1; } } } I completely understand why this exception is thrown when enumerating a list- it seems reasonable to expect that during enumeration, the Structure of the enumerated object does not change. However- does changing a Value of a dictionary changes its Structure ? Specifically, the structure of its keys? I see

I just want to know the best way to emulate a C# style enumeration in Ruby. Specifically, I would like to be able to perform logical tests against the set of values given some variable. Example would be the state of a window: "minimized, maximized, closed, open" If you need the enumerations to map to values (eg, you need minimized to equal 0, maximised to equal 100, etc) I'd use a hash of symbols to values, like this: WINDOW_STATES = { :minimized => 0, :maximized => 100 }.freeze The freeze (like nate says) stops you from breaking things in future by accident. You can check if something is

Swift enumerations have both associated and raw values. But the use cases of these values is not clear to me. So I would really appreciate if anyone can explain the difference between the associated and raw values, an example would be very helpful. Raw values are for when every case in the enumeration is represented by a compile-time-set value. The are akin to constants, i.e. let A = 0 let B = 1 is similar to: enum E: Int { case A // if you don't specify, IntegerLiteralConvertible-based enums start at 0 case B } So, A has a fixed raw value of 0 , B of 1 etc set at compile time. They all have
