factory

问题 I have made several changes to both debug and release settings and now I want to return to factory settings. How could I do that? 回答1: There is no easy way to go back to the default configuration for a project file. When you create a new project it's based off a template located in your Visual Studio directory (e.g. C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplates\CSharp\Windows\1033\ClassLibrary.zip) and VS has no way of reapplying the template. However, you

问题 I have created an Enum to define certain actions. Programming against a external API I am forced to use an Integer to express this action. That's why I have added an integer instance field to my Enum. This should be d'accord with Joshua Bloch's Effective Java, instead of relying on ordinal() or the order of the Enum constants using values()[index] . public enum Action { START(0), QUIT(1); public final int code; Protocol(int code) { this.code = code; } } I get an integer value what from the

问题 I am trying to generate a bean that would represent java.nio.file.Path using a static method Paths.get(String path) . my current Spring setup looks as follows: <bean id="myPath" class="java.nio.file.Paths" factory-method="get"> <constructor-arg value="c:\\tmp\\" /> </bean> but it comes back with an excpetion No matching factory method found: factory method 'get' . Any ideas why that is the case? 回答1: java.nio.file.Paths.get expects URI. Besides, this is xml not java don't use \\ Try as file:

问题 I'm perfectly willing to play with this until I get it right, but was hoping someone might give me a hint. The parameter is declared in the docs (gen-dartdocs/dart-mirrors/ClassMirror/newInstance.html) as InstanceMirror newInstance(Symbol constructorName, List positionalArguments, [Map<Symbol,dynamic> namedArguments]); There is a nice writeup on the format of positionalArguments and namedArguments in the docs. However, it is just a little on the abstract side of my current tolerance level. A

问题 I am trying to use Guice 3.0 AssistedInject , and it won't instantiate the factory. SSCCE Code: Parent class public class ParentClass() { @Inject private MyFactory myFactory; private final Foo foo; private final Bar bar; public ParentClass() { if(myFactory == null) System.err.println("Error: I should have injected by now!"); foo = myFactory.create(new Map<String, Object>()); // etc. } } Factory Interface public interface MyFactory { Foo create(Map<String, Object> mapA); Bar create(Map<String,

问题 I am working on hiding or showing elements based on user role from an api. The directive works when I set the data.roleName in the code but when I try to set it by I service I need to resolve a promise before loading the rest of the directive though I keep getting "cannot read property of undefined errors Here's the code. .js app.directive('restrictTo', ['SecuritySvc', function (SecuritySvc) { return { restrict: 'EA', replace: true, transclude: true, scope: {}, controller: ['$scope', '$attrs'

问题 i have the problem in writing a C++ framework, that users should have less overhead than possible to use it. Users can publish their work to the frameworks by creating a shared library that contains a class, which is derived by a frameworks' BaseClass and implementing an extern "C" createInstance()-method in order to return an instance its' derived class. So the framework can access the user class by calling the createInstance-Method through the shared library with dlsym(). class BaseClass{}

问题 I am using windsor castle as my IoC container, and has run in to a bit of a problem. This is best explained in code, so I´ll give it a try. I have a factory class, that should provide me with implementations of a certain interface: public interface IObjectCreatorFactory { IObjectCreator GetObjectCreator(Type objectType); } public interface IObjectCreator { T CreateObject<T>(IDataRow data); bool SupportsType(Type type); } Implementation of the factory class could look like this, though I am

问题 I am attempting to call multiple $http request in a factory which I Am using to flush out multiple inputs with data and set default selections. I Want to then call a promise once all 3 of these are done to call in the real form data (if there is any, sometimes there will not be in which case it will do nothing) to overwrite the defaults in place. So here is my attempt at this - the factory I set up a factory to call all 3 inputs and their defaults (I am being sent them individually, i cannot

问题 I am currently stuck at trying to write a factory class that doesn't rely on service location. The only other alternative I can think of is to use constructor injection to inject all possible instances, but that may lead to surprises as classes are passed via reference. It is also possibly going to be costly and messy once the number of possible providers grow. The providers themselves are full complex classes that have their own dependencies so manual construction is out of the picture.
