interface

问题 I need advice on interfaces. I have a class called Unit which can attack other units. The attack can be air or ground. I need single method to achieve attacking called attack() . Some units can only attack ground units, some air units or both. This is what I've come up so far: public interface Attack() { public void attack(SCObject object); } public interface GroundAttack() extends Attack { public void groundAttack(SCObject object); } public interface AirAttack() extends Attack { public void

问题 I want to use the Dependency Injection pattern in C#, and I want to have the logics as separated as possible in namespaces. Question In which namespace should the interface of the consumed class be? Motivation of the question First let's do some "normal" case. A book-case to be used as the basis for the second part of the explanation. Then, the "real-life" case, which arises the question. Book case Let's assume the coder is Alice and that she uses Alice as a top-level name in the namespaces

问题 NOTE: I am aware that this is dangerously close to many other questions. I haven't seen any, however, that do not pertain specifically to Android's OnClickListener interface. I am asking in a general sense. I understand the difference between instantiating an interface via an anonymous class... a la: private final Runnable runnable = new Runnable() { @Override public void run() { draw(); } }; ... and extending the interface. public class ClassyClass implements Runnable { ... //do other cool

问题 Lets say I have an interface with a field - String type = "interface". It's implementing class has a field - String type = "class". Is there any way to access the interface's field through that class anymore? 回答1: Yep.. because basically interface variable are public static final or in other word, a constant.. you can access it in a static way using your IYourInterfaceName.type 回答2: public interface Firstone { String type="interface"; } public class Abc implements Firstone { /** * @param args

问题 I have got a form with a TJvComboEdit control (from Jedi Visual Components library, jvcl) on it. This control has got an AutoCompleteList and if I set AutoCompleteOptions to acoUpDownKeyDropsList I can at runtime show this list by pressing the up or down key. So far, that's fine, but in addition to that I want the control's button to also show that list (like a TComboBox button does) but I can not find any way to do that. The showing of the list seems to be done by some internal IAutoComplete

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I got a interface which describes a way to do some action on some item which is looked up in some repository. And i see two ways to create that interface. public interface IService<T> where T : class { void Action<TSource>(int id, TSource source, Action<T> action) where TSource : IRead<T>; } versus public

问题 I'm creating a c# Project with WCF Service, I use 3-Tiers Architecture. I create my WCF Service as below : namespace MyApp.WCFService { [ServiceContract] public interface IServiceWCF { [OperationContract] string SayHello(string who) } } namespace MyApp.WCFService { public class ServiceWCF : IServiceWCF { public string SayHello(string who) { return "Hello" + who + "from Web Service"; } } } This works great, but in my solution I had another project with methods. I would like to know if it's

问题 I'm a huge fan of coding against interfaces. In the WCF world, this highly emphasized on every service. However, I'm getting deeper into ASP.NET Web Api, as an extension of MVC 4, I was curious to see if there was some typical reasoning to have your controller implementations inherit from an interface. I know the default settings for ASP.NET Web Api look something like this public class TestsController : ApiController { public IEnumerable<string> Get() { var testValues = new List<string> {

问题 When I add an "XmlAttribute/XmlElement" to a property in an Interface and 100 other classes inherit from this interface, when Serializing the object to XML - why doesn't the attributename I entered show up in the XML file after serialization? interface Test { [XmlAttribute("Name")] bool PropertyName { get; set; } } when saving the file, is shows "PropertyName" and not "Name". Is there any way to make it work, so a proeprty with an XmlAttributes added to an interface changes the Value

问题 I have an inner AsyncTask which i have call from a fragment outside the fragment which contains this AsyncTask. I have read and saw some examples where they use an interface. I can't figure it out on how to implement it in my project. This is my inner AsyncTask: public class LoadQueueTask extends AsyncTask<Void, Void, Queue> { @Override protected Queue doInBackground(Void... arg0) { Model model = Model.getInstance(); return model.getQueue(); } @Override protected void onPostExecute(Queue
