Let\'s say I have a class Foo with plugin traits/roles Bar and Baz, where Baz is dependent on Bar. package Foo;
I have use traits ui to create a program. I am trying to make the program close its window, so it may be like a transition screen but it doesn\'t 开发者_开发百科work.
How do I get the \"dereferenced type\" of another type in C++03?Note that it can be other dereferenceable type like std::vector<int>::iterator.
Apart from the inheritance aspect, is there a di开发者_如何学Cfference between the following class templates:
Please let me know if this is inappropriate as formulated (in particular whether Programmers开发者_如何学C.SE or something would be better for the question.)
If I have the following Scala class: abstract class MyOrdered extends Ordered[MyOrdered] { def id: Int def compare(that : MyOrdered) : Int =
does somebody know why @Test annotated methods which are inherited from a Scala trait are not found by the JUnit 4 test run开发者_JAVA百科ner? It gives me \"No JUnit tests found\".
Say I have two traits that I would like to mixin to a class. The traits each implement an abstract method that the class needs.
I am designing class, which is almost the same for 2d and 3d, so I am trying to use templates, to create it as one class typed by vector type (2d od 3d)
It seems like Traits could completely replace interfaces, abstract base classes, mixins, and multiple inheritance, leaving you with just Traits and concrete inheritance.
