interface

问题 I typed this simplified example without the benefit of an IDE so forgive any syntax errors. When I try to automap this I get a FluentConfigurationException when I attempt to compile the mappings - "Association references unmapped class IEmployee ." I imagine if I were to resolve this I'd get a similar error when it encounters the reference to IEmployer as well. I'm not opposed to creating a ClassMap manually but I prefer AutoMapper doing it instead. public interface IEmployer { int Id{ get;

问题 Is it possible in Android to capture screen rotate events but not actually have the activity respond to the rotate events? To make things more difficult, I've got an activity backed by a TabActivity, and in one of the tabs I want to rotate some of the content area on screen - but leave the tab in portrait mode. I've tried setting the activity orientation to portrait in the manifest, but then I no longer get the onConfigurationChanged(..) events. However, If I remove this line, the whole tab

问题 I have already looked upon the the usage of interface, abstract classes and inheritance. I see that each have their uses but, I am still kind of confused. I know that generally a class can extend only another class, although some may support multiple inheritance, but it can implement more than one interface (which is probably the main reason for using an interface). However this class can also be extended by another class If I am correct. I have also seen that abstract classes may be faster

问题 I'm reading the docs on the UIBinder of GWT and the first code snippet made me confused: public class HelloWorld extends UIObject { // Could extend Widget instead interface MyUiBinder extends UiBinder<DivElement, HelloWorld> {} private static MyUiBinder uiBinder = GWT.create(MyUiBinder.class); @UiField SpanElement nameSpan; public HelloWorld() { // createAndBindUi initializes this.nameSpan setElement(uiBinder.createAndBindUi(this)); } } On the second line an interface is created locally which

问题 I was reading my old SCJP 6 book(author Kathy Sierra,Bert Bates) mentioned All the interface methods are implicitly public and abstract by default interface methods must not be static For example, if we declare interface Car { void bounce(); //no need of public abstract void setBounceFactor(int b); //no need of public abstract } What the compiler sees interface Car { public abstract void bounce(); public abstract void setBounceFactor(int b); } But from Java 8 , interfaces can now define

问题 Im making a text game that has an abstract Fighter class. within Fighter I have a variable called protected boolean isGround. then I have 2 abstract classes that extend Fighter called AirFighter and GroundFighter that basically set that isGround to be True or False, depending on if they are ground units or not. I then want to set up the game so that in my battle phase the game checks if player 1's speed is faster then player 2, and depending on who is faster to then do like p1.attack(p2), and

问题 My problem is similar to this post: Interface inheritance in Entity Framework Thus, I copy that example and modify it for my issue: public interface IBaseEntity { DateTime CreatedOn { get; set; } string CreatedBy { get; set; } } // The following two classes are generated by Entity Framework public partial class SomeEntity { public int SomeEntityId { get; } public string Name { get; set; } public DateTime CreatedOn { get; set; } public string CreatedBy { get; set; } } public partial class

问题 I have app structure - public abstract class a { } //defined in a.dll public abstract class b { } //defined in b.dll //Above 2 DLL reference added in main project where I want to derive both of this abstract classee like public abstract class proj : a, b { } I am able to derive any one of it only not both. So pls guide me on missing things or wrong coding I had done. 回答1: You can't multiple inherit using C#. You can however achieve this by using an interface. public interface Ia { } public

问题 I'm trying to create a C# wrapper for a C .lib that contains functions take take a void pointer using SWIG. int inputPointExample(void* input); int outputPointerExample(void* output); By default SWIG doesn't handle void pointer conversions, you have to use typemaps somehow. I found this page -> http://www.nickdarnell.com/2011/05/swig-and-a-miss/ Number 9 says to use the following typemaps to handle void pointers... %typemap(ctype) void * "void *" %typemap(imtype) void * "IntPtr" %typemap

问题 I need some feedback on C# - cPython integration for scientific application. The scenario is the following: C# for data acquisition and visualization - CPython for data manipulation using several and changing third part library to implement domain specific tasks. General use case: C# code get realtime data from device C# code pass data to cPython code and ask for elaboration Cpython code does the magic Cpython code pass result back to c# code C# visualizes data in a WPF application Both c#
