fluent-interface

问题 I have a base class public class BaseClass { public int Id {get; set;} } and two derived classes public class Foobar: BaseClass { [Required] public int Whatever {get; set;} } public class Snafu: BaseClass { [Required] public int Whatever {get; set;} } I'm using Table Per Hierarchy inheritance and trying to cut down on my duplicate columns, so with Fluent API I've mapped them like so: modelBuilder.Entity<Foobar>().Property(fb => fb.Whatever).HasColumnName("Whatever"); modelBuilder.Entity<Snafu

问题 I am attempting to use the Fluent-NHibernate automapping functionality (in the latest version of the software) and am running into problems using Guids as the Primary Key fields. If I use integer fields for the primary keys, the tables are generated successfully and all Nhibernate functionality seems to work fine. FYI, I am using NHibernate to generate my database tables. Here are a couple of classes with integer IDs. using System; using System.Collections; using System.Collections.Generic;

问题 I am currently using a Get Request with proxy information: String result1 = Request.Get("_http://somehost/") .version(HttpVersion.HTTP_1_1) .connectTimeout(1000) .socketTimeout(1000) .viaProxy(new HttpHost("myproxy", 8080)) .execute().returnContent().asString(); The result is a "Proxy Authentication Required" error. I believe a username and password is required from the server making the request? If so, how do I add that detail? I have never used the Fluent API before. 回答1: You need a

问题 Can I use code first attributes in combination with fluent-API configurations for my entities in Entity Framework? Thank you. 回答1: Yes you can. I generally prefer to define some constraints (for example, making a property required by using [Required] or to define a length for a string property by using StringhLength(1, 10) ): [Required] [StringLentgh(1,10)] public string BookName {get;set;} On the other hand, I generally use fluent api to define the relationships (for example, 1-to-many

问题 When using auto-registration with castle windsor I see people doing things like _container.Register( AllTypes.Pick().FromAssembly(Assembly.GetExecutingAssembly()) .WithService.FirstInterface()); For the life of me I can't figure out what the Pick() method does nor can I find any documentation. Can anyone explain it to me? 回答1: Pick(IEnumerable<Type>) is a synonym for From(IEnumerable<Type>) , i.e. it selects the specified types as registration targets. AllTypes.Pick() is the same as AllTypes

问题 I am trying to implement nhibernate transaction handling through Interceptors and couldn’t figure out how to register the interface through fluent mechanism. I see a Component.For<ServicesInterceptor>().Interceptors but not sure how to use it. Can someone help me out? This example seemed a little complex. 回答1: You do it in two steps: You need to register the interceptor as a service in the container: container.Register(Component.For<MyInterceptor>()); You register the component you want to

问题 I have an OOP related problem with Flash, actionscript 3. It's a personal project, and I am looking for a design pattern or workaround for this problem, and my goal is to learn new things. I have created a class called Chain. I created this util-class to make delayed function calling easy. You can make a chain of functions, by adding them with a delay in milliseconds. This chain can be executed multiple times, even in reversed order. This class has functions which returns itself. That makes

问题 I'm currently occupying myself with implementing a fluent interface for an existing technology, which would allow code similar to the following snippet: using (var directory = Open.Directory(@"path\to\some\directory")) { using (var file = Open.File("foobar.html").In(directory)) { // ... } } In order to implement such constructs, classes are needed that accumulate arguments and pass them on to other objects. For example, to implement the Open.File(...).In(...) construct, you would need two

问题 I have tried to find a good introduction on chainable OOP objects in PHP, but without any good result yet. How can something like this be done? $this->className->add('1','value'); $this->className->type('string'); $this->classname->doStuff(); Or even: $this->className->add('1','value')->type('string')->doStuff(); Thanks a lot! 回答1: The key is to return the object itself within each method: class Foo { function add($arg1, $arg2) { // … return $this; } function type($arg1) { // … return $this;
