proxy-classes

问题 I have a ServiceContract , using System.Collections.Generic; using System.ServiceModel; namespace MainModule.Sub.Communication { [ServiceContract] public interface IWebMethod { [OperationContract(IsOneWay = false)] bool InvokeAlert(List<int> userIds); [OperationContract(IsOneWay = false, Name = "InvokeAlertByMainID")] bool InvokeAlert(List<int> userIds, int mainId); [OperationContract(IsOneWay = true)] void DeletePopupNotifications(System.Data.DataSet deletedNotifications); } } I used below

问题 I have a data structure which uses composite ids (Which I dont wish to change to single) Everything loads fine except for many-to-one joins which if the join is empty, instead of mapping the property to null, maps it to an empty proxy object. I have written an ugly work around( see bleow). Any solutions to this? private Node _Parent; public Node Parent { get { return this._Parent; } set { this._Parent = Proxy.Check<Node>(value); } } internal static class Proxy { public static T Check<T>(T obj

问题 I recently stumbled up this proxy class for making c++ primitive members "read only" (publicly act as const references, but privately non const). This potentially eliminates the need for boilerplate "getters". The proxy class looks like: template <Container,Primitive> class RO { friend Container; public: inline operator Primitive() const { return x; } template<typename Other> inline bool operator==(const Other& y) const { return x == y; } template<typename Other> inline bool operator!=(const

问题 Anyone knows how to inject a dependency to a @ControllerAdvice? My @ControllerAdvice extends Spring's ResponseEntityExceptionHandler and implements no interfaces. The @ControllerAdvice gets called correctly, but the @Autowired dependency is never injected. There are no startup injection errors, the dependency is simply null. I guess it has to do with how Spring proxies the @ControllerAdvice with cglib so that the @Autowired annotation gets lost. I tested by implementing an interface, so that

问题 I'm trying to access a QA environment website using Net::HTTP::Proxy to get the response.But I keep getting a SocketError whenever I try to connect. Please find the code snippet that I'm trying to use. proxy_addr = "http://autoproxy1.qa.com" proxy_class = Net::HTTP::Proxy(proxy_addr,80).start("mywebsite.com") This is the Error I'm getting SocketError: getaddrinfo: Name or service not known from /site/ruby/ruby-1.9.1-4/lib/ruby/1.9.1/net/http.rb:581:in `initialize' from /site/ruby/ruby-1.9.1-4

问题 This question already has answers here : Typescript typings, generics and abstract classes (2 answers) Closed 2 years ago . This is somewhat the transformation of a question I posted somewhere else yesterday. My objective is not to get a working result but to have a better understanding of the kind of design I can obtain while returning the correct types. This by using here a minimalist example, so please don't tell me it's useless or does nothing. Code sample (Try it in Typescript playground

问题 Item 30 of Scott Meyers' "more effective C++" maps out a 'proxy object' programming design-pattern. The problem is if you have: X x; x[3]=42; cout<<x[3] ... you need X's operator[] overload to be able to distinguish between L-value and R-value use. (maybe you need different code to run,e.g. in the first case heavy copying might be involved, but in the second case maybe we can just pass back a reference). The proxy pattern is that X contains a Proxy class, and X's operator[] overloads return

问题 I want to wrap simple POJO class. The thing is I know nothing about that class beforehand, only that it's POJO with setters and getters. I want to substitute this class with my Proxyclass so that every time client calls getter or setter I would be able to intercept that call. So when the call is intercepted, I want to do some pre-get(or set) operation, then invoke the getter(or setter), and then to do some post-get(or set) operations. I'm creating my proxy like that private Pojo

问题 I have entities which form a tree relationships. class MyEntity { public int Id {get;set;} public int ParentId {get;set;} public virtual MyEntity Parent {get;set;} public virtual ICollection<MyEntity> Children {get;set;} } When these entities are called without AsNoTracking() relationships are fixed up. var entities = MyEntitiesSet.ToList(); All navigation properties and collections are set. However if AsNoTracking() is called: var entities = MyEntitiesSet.AsNoTracking.ToList(); no navigation

问题 I want to make my variable (a proxy object) evaluate to false when used in conditional sentences. I know I can use .nil? and even var == nil but I think that's not good enough. What I am trying go do is to: if myproxy # not only myprroxy.nil? or myproxy == nil, but just that # myproxy's backend object is not nil else # myproxy's backend object is nil end Any ideas? 回答1: The only two objects that evaluate to a false-ish value in a boolean context in Ruby are nil , the singleton instance of
