A static function, unlike a regular (instance) function, is not associated with an instance of the class. A static class is a class which can only contain static members, and therefore cannot be instantiated. For example: class SomeClass { public int InstanceMethod() { return 1; } public static int StaticMethod() { return 42; } } … Read more
You need to delimit each parameter name with a “:” at the very least. Technically the name is optional, but it is recommended for readability. So you could write: – (NSMutableArray*)getBusStops:(NSString*)busStop :(NSTimeInterval*)timeInterval; or what you suggested: – (NSMutableArray*)getBusStops:(NSString*)busStop forTime:(NSTimeInterval*)timeInterval;
I think the shortest way to do just throw-away single call (without altering existing modules or creating new ones) would be as follows: Class.new.extend(UsefulThings).get_file
It doesn’t seem like there’s any point to it. According to the Java Language Specification 4.12.4: Declaring a variable final can serve as useful documentation that its value will not change and can help avoid programming errors. However, a final modifier on a method parameter is not mentioned in the rules for matching signatures of … Read more
You’re checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class. You should be doing something more like this: class MyClassTest { [TestMethod] public void MyMethodTest() { string action = “test”; Mock<SomeClass> mockSomeClass = new Mock<SomeClass>(); mockSomeClass.Setup(mock => mock.DoSomething()); MyClass myClass = new MyClass(mockSomeClass.Object); myClass.MyMethod(action); // … Read more
I like to quote Peters’ Zen of Python. “Explicit is better than implicit.” In Java and C++, ‘this.‘ can be deduced, except when you have variable names that make it impossible to deduce. So you sometimes need it and sometimes don’t. Python elects to make things like this explicit rather than based on a rule. … Read more
No, they can’t. I can understand that the enum class part for strongly typed enums in C++11 might seem to imply that your enum has class traits too, but it’s not the case. My educated guess is that the choice of the keywords was inspired by the pattern we used before C++11 to get scoped … Read more
I prefer such helper methods to be private static; which will make it clear to the reader that they will not modify the state of the object. My IDE will also show calls to static methods in italics, so I will know the method is static without looking the signature.
ES6 style allows you to use new features, such as super keyword. super keyword it’s all about parent class context, when you are using ES6 classes syntax. As a very simple example, checkout: Remember: We cannot invoke parent static methods via super keyword inside an instance method. Calling method should also be static. Invocation of … Read more
Change “methodInfo” to “classInstance”, just like in the call with the null parameter array. result = methodInfo.Invoke(classInstance, parametersArray);
