architecture

问题 It is possible to check if an app bundle's binary process is running in 32 or 64 bit mode, as answered in this question, but I can verify that it only works with GUI processes. However, I need to also check processes that don't have a GUI and is not part of a bundle. So, programmatically, without calling system functions or other executables , how can I test if any process is running in 32 or 64 bit mode, given the process pid? 回答1: Ok, so I finally found the answer was already on SO here,

问题 I'm trying to find out the system architecture using Java and I've tried out: operatingSystemMXBean.getArch() and String sys1=System.getProperty("sun.arch.data.model") but I get amd64 when I'm using an Intel 64 bit processor. I've read this article on Wiki to clear up my concepts. Am I missing something? Also, how can I get the actual System architecture using Java so that I get an output saying Intel 64? Thanks! 回答1: Intel 64-Bit-Processors use the amd-architecture. That's why many systems

问题 I am using Dependency Injection. Say that I has an OrderService class like this: public class OrderService{ public OrderService( IOrderValidator validator , IOrderRepository repository , IOrderNotificator notificator){ //assign global fields } public void SubmitOrder(Order ord){ if(validator.IsOrderValid(ord)){ repository.InsertNew(ord); notificator.Notify(ord); } } } Now I wonder to create a facade class for example TypeAOrderService , as inherited by OrderService, with components declared

问题 How do you expose an aggregate member for the purpose of presentation, while at the same time preventing that member from getting modified directly? So, I need something like read-only access to that member for the purpose of showing it on UI, For example: class A { B b; void doSomething() { b.update(); } } class B { String getTitle() { return title; } Items getItems() { return items; } void update() { ... } } interface SomeView { void show(Items items); } The quick-and-dirty solution would

问题 This is a design related question. Lets say we have a public API called ClientAPI with a few web methods like CreateAccount, GetAccount. Depending on the customer, we use a number of different providers to fulfil these requests. So say we have ProviderA and ProviderB and ProviderC. ProviderA has a method signature/implementation of CreateAccount that needs (Firstname, Lastname) only and creates an account with ProviderA. ProviderB has a method signature/implementation of CreateAccount that

问题 I've got a web project, where I need to model some basic JavaScript classes and put them into a separate javascript file. Now I want to use them locally on a page and add them into a master view model, which acts as binding object. My question is, how do you realize the connections between model class and master view model? This is the class model from the api: Namespace.Problem = function() { var self = this; self.identifier = ko.observable(); self.summary = ko.observable(); self.title = ko

问题 I currently have a fairly large application (about 30k lines of code). I generated a dependency graph using the architecture tool within VS2010. I am trying to export it to XPS, as it states I can, and it will stop at about 300KB, and will not open in XPS viewer. Any ideas on why it is stopping the export and corrupting the file, or is it? Thanks! 回答1: You can pass by another structure before converting your diagram to XPS, for example save it as an image, to do it : Right-click the graph

问题 I'm trying to build libFLAC to use in a project of mine, however when it comes to linking, GCC ignores the library because it says it was not built for the current architecture (i386). When I compile the program in 64-bit, it links the library properly which means the library was compiled for x86_64 architecture. Unfortunately, my program wont work in 64-bit, so I need to compile libFLAC as i386. I've tried using ./configure --build=i386 however it didn't seem to change anything. So far, I've
