  • Upper extension method in linq to NHibernate

    - by Daniel
    I would like to use the Upper extension method which is declared on the IDbMethods interface against Sql Server 2008. I understand that this will translate to UPPER() on sql server. However I can not figure out how to get an implementation of IDbMethods so that I can use the extension method.

  • Mock static method Activator.CreateInstance to return a mock of another class

    - by Jeep87c
    I have this factory class and I want to test it correctly. Let's say I have an abstract class which have many child (inheritance). As you can see in my Factory class the method BuildChild, I want to be able to create an instance of a child class at Runtime. I must be able to create this instance during Runtime because the type won't be know before runtime. And, I can NOT use Unity for this project (if so, I would not ask how to achieve this). Here's my Factory class that I want to test: public class Factory { public AnAbstractClass BuildChild(Type childType, object parameter) { AnAbstractClass child = (AnAbstractClass) Activator.CreateInstance(childType); child.Initialize(parameter); return child; } } To test this, I want to find a way to Mock Activator.CreateInstance to return my own mocked object of a child class. How can I achieve this? Or maybe if you have a better way to do this without using Activator.CreateInstance (and Unity), I'm opened to it if it's easier to test and mock! I'm currently using Moq to create my mocks but since Activator.CreateInstance is a static method from a static class, I can't figure out how to do this (I already know that Moq can only create mock instances of objects). I took a look at Fakes from Microsoft but without success (I had some difficulties to understand how it works and to find some well explained examples). Please help me! EDIT: I need to mock Activator.CreateInstance because I want to force this method to return another mocked object. The correct thing I want is only to stub this method (not to mock it). So when I test BuildChild like this: [TestMethod] public void TestBuildChild() { var mockChildClass = new Mock(AChildClass); // TODO: Stub/Mock Activator.CreateInstance to return mockChildClass when called with "type" and "parameter" as follow. var type = typeof(AChildClass); var parameter = "A parameter"; var child = this._factory.BuildChild(type, parameters); } Activator.CreateInstance called with type and parameter will return my mocked object instead of creating a new instance of the real child class (not yet implemented).

  • Calling a static method on a generic type parameter

    - by Remi Despres-Smyth
    I was hoping to do something like this, but it appears to be illegal in C#: public Collection MethodThatFetchesSomething<T>() where T : SomeBaseClass { return T.StaticMethodOnSomeBaseClassThatReturnsCollection(); } I get a compile-time error: "'T' is a 'type parameter', which is not valid in the given context." Given a generic type parameter, how can I call a static method on the generic class? The static method has to be available, given the constraint.

  • Method overriding

    - by Gandalf StormCrow
    Can you override method in java without using annotations? Because eclipse doesn't support it if you use JRE6, you need to switch back to 5 to use @Override annotation. Will this method be overriden if I remove the annotation? @Override public String toString() { return name + " [" + genre + "]"; }

  • How can I find the method that called the current method?

    - by flipdoubt
    When logging in C#, how can I learn the name of the method that called the current method? I know all about System.Reflection.MethodBase.GetCurrentMethod(), but I want to go one step beneath this in the stack trace. I've considered parsing the stack trace, but I am hoping to find a cleaner more explicit way, something like Assembly.GetCallingAssembly() but for methods.

  • Use Windbg find argumet passed to a COM+ method

    - by G33kKahuna
    Generated a debug diagnostic dump file for a COM+ application. Upon analysis look like threads deadlocks at line OLE32!SwitchSTA. My symbol path is pointing to msdl.microsoft.com/download/symbols. Is there way to know what arguments were passed to this method? In general, how does one use Windbg to find the input argument value to the method call? thanks in advance

  • access exception when invoking method of an anonymous class using java reflection

    - by Asaf David
    Hello I'm trying to use an event dispatcher to allow a model to notify subscribed listeners when it changes. the event dispatcher receives a handler class and a method name to call during dispatch. the presenter subscribes to the model changes and provide a Handler implementation to be called on changes. Here's the code (I'm sorry it's a bit long). EventDispacther: package utils; public class EventDispatcher<T> { List<T> listeners; private String methodName; public EventDispatcher(String methodName) { listeners = new ArrayList<T>(); this.methodName = methodName; } public void add(T listener) { listeners.add(listener); } public void dispatch() { for (T listener : listeners) { try { Method method = listener.getClass().getMethod(methodName); method.invoke(listener); } catch (Exception e) { System.out.println(e.getMessage()); } } } } Model: package model; public class Model { private EventDispatcher<ModelChangedHandler> dispatcher; public Model() { dispatcher = new EventDispatcher<ModelChangedHandler>("modelChanged"); } public void whenModelChange(ModelChangedHandler handler) { dispatcher.add(handler); } public void change() { dispatcher.dispatch(); } } ModelChangedHandler: package model; public interface ModelChangedHandler { void modelChanged(); } Presenter: package presenter; public class Presenter { private final Model model; public Presenter(Model model) { this.model = model; this.model.whenModelChange(new ModelChangedHandler() { @Override public void modelChanged() { System.out.println("model changed"); } }); } } Main: package main; public class Main { public static void main(String[] args) { Model model = new Model(); Presenter presenter = new Presenter(model); model.change(); } } Now, I except to get the "model changed" message. However, I'm getting an java.lang.IllegalAccessException: Class utils.EventDispatcher can not access a member of class presenter.Presenter$1 with modifiers "public". I understand that the class to blame is the anonymous class i created inside the presenter, however I don't know how to make it any more 'public' than it currently is. If i replace it with a named nested class it seem to work. It also works if the Presenter and the EventDispatcher are in the same package, but I can't allow that (several presenters in different packages should use the EventDispatcher) any ideas?

  • Why do we need to use out keyword while calling a method

    - by Midhat
    When a method is defined with an out parameter, why do I have to specify the out keyword when calling it. Its already there in the method definition, and the runtime should know that any parameter passed will be an out parameter. It would make sense if the compiler will accept the argument with or without out keyword, with different semantic, but if you MUST add the keyword to make the code compile, whats the use? Shouldn't the compiler handle it automatically? Same for ref

  • Why is the setContextClassLoader() method placed on Thread ?

    - by Roman
    Why is the setContextClassLoader() method placed on thread ? What different thread have different classloaders? The question is what if i extended a classloader , loaded there some new classes. to the my custom classloader. Now , I want it to be the context classloader , so I call the method (Thread.currentThread().setContextClassLoader(loader)). Are these new classes awailable only in the context of the current Thread ? ( or how does it work ?) Thanks

  • Java method missing (ala Ruby) for decorating?

    - by cibercitizen1
    Is there any technique available in Java for intercepting messages (method calls) like the method_missing technique in Ruby? This would allow coding decorators and proxies very easily, like in Ruby: :Client p:Proxy im:Implementation ------- ---------- ----------------- p.foo() -------> method_missing() do_something im.foo() ------------------> do_foo p.bar() --------> method_missing() do_something_more im.bar() -------------------> do_bar (Note: Proxy only has one method: method_missing())

  • Avoid compiling when using Decimal.Round() method (C#/CF)

    - by Christian Almeida
    Is there a way to tell to VS2005 to get compiler error when using "some defined" method? It probably sounds strange, but I do not want to compile when using Decimal.Round(). Reason: CF does not round by "awayfromzero", so I created a method to do this job. But sometimes I (and team) forget that is not to use Decimal.Round. So I'd like to get a compiler error when using it.

  • In an extension method how do a create an object based on the implementation class

    - by Greg
    Hi, In an extension method how do a create an object based on the implementation class. So in the code below I wanted to add an "AddRelationship" extension method, however I'm not sure how within the extension method I can create an Relationship object? i.e. don't want to tie the extension method to this particular implementation of relationship public static class TopologyExtns { public static void AddNode<T>(this ITopology<T> topIf, INode<T> node) { topIf.Nodes.Add(node.Key, node); } public static INode<T> FindNode<T>(this ITopology<T> topIf, T searchKey) { return topIf.Nodes[searchKey]; } public static bool AddRelationship<T>(this ITopology<T> topIf, INode<T> parentNode, INode<T> childNode) { var rel = new RelationshipImp(); // ** How do I create an object from teh implementation // Add nodes to Relationship // Add relationships to Nodes } } public interface ITopology<T> { //List<INode> Nodes { get; set; } Dictionary<T, INode<T> > Nodes { get; set; } } public interface INode<T> { // Properties List<IRelationship<T>> Relationships { get; set; } T Key { get; } } public interface IRelationship<T> { // Parameters INode<T> Parent { get; set; } INode<T> Child { get; set; } } namespace TopologyLibrary_Client { class RelationshipsImp : IRelationship<string> { public INode<string> Parent { get; set; } public INode<string> Child { get; set; } } } public class TopologyImp<T> : ITopology<T> { public Dictionary<T, INode<T>> Nodes { get; set; } public TopologyImp() { Nodes = new Dictionary<T, INode<T>>(); } } thanks

  • Why does std queue not define a swap method specialisation

    - by Jamie Cook
    I've read that all stl containers provide a specialisation of the swap algorithm so as to avoid calling the copy constructor and two assignment operations that the default method uses. However, when I thought it would be nice to use a queue in some code I was working on I noticed that (unlike vector and deque) queue doesn't provide this method? I just decided to use a deque instead of a queue, but still I'm interested to know why this is?
