  • Reinject dependencies of a freshly deserialized object

    - by NathanE
    If a program has literally just deserialized an object (doesn't really matter how, but just say BinaryFormatter was used). What is a good design to use for re-injecting the dependencies of this object? Is there a common pattern for this? I suppose I would need to wrap the Deserialize() method up to act as a factory inside the container. Thanks!

  • Hero Class, php classes

    - by John
    I am going to have different classes for a character that a user play. Like "Mage, Warrior" etc. I am thinking of a method like have some CharacterBase class (abstract?) and then I have a child class which is like WarriorClass or something like that. I think the approach is called Factory pattern or something like that. Anyone got a clue of what I'm trying to achieve here, and are there perhaps any better way to do this?

  • Is it ok to reference .Net assemblies liberally?

    - by panamack
    I'm building a WPF application and working with the MVVM pattern. I have 4 projects in my solution, 3 class libraries, Data, Model and ViewModel and the WPF executable View. Is there anything wrong with the Model referencing WindowsBase so that I can use ObservableCollection<T> for example or can I just make use of what I intuitively feel I need without worrying about the original purposes of the class in the framework e.g. collection databinding.

  • extract variables from an expression using javascript regexp

    - by powerboy
    For example, here is a string representing an expression: var str = 'total = sum(price * qty) * 1.09875'; I want to extract variables (i.e., 'total', 'price' and 'qty' but not 'sum' since 'sum' is a function name) from this expression. What is the regexp pattern in javascript? Variable name consists of letters, digits, or the underscore, beginning with letters or the underscore.

  • Dynamicall Rendering in a Scrollable Area

    - by James
    What is the generic algorithm or process that is commonly used to dynamically render portions of a scrolling area? For example, in Google Maps, when the user scrolls past the bounds of the currently rendered area, a grey checkerboard pattern is displayed within the not-yet-rendered portions while the application loads and renders those areas. I'm looking specifically for the approach, or the mathematics, related to filling a graphics area in chunks based on what has just come into view. If possible, I'm looking for anything relevant to the GDI+ process of doing so.

  • nodejs async.waterfall method

    - by user1513388
    Update 2 Complete code listing var request = require('request'); var cache = require('memory-cache'); var async = require('async'); var server = '172.16.221.190' var user = 'admin' var password ='Passw0rd' var dn ='\\VE\\Policy\\Objects' var jsonpayload = {"Username": user, "Password": password} async.waterfall([ //Get the API Key function(callback){ request.post({uri: 'http://' + server +'/sdk/authorize/', json: jsonpayload, headers: {'content_type': 'application/json'} }, function (e, r, body) { callback(null, body.APIKey); }) }, //List the credential objects function(apikey, callback){ var jsonpayload2 = {"ObjectDN": dn, "Recursive": true} request.post({uri: 'http://' + server +'/sdk/Config/enumerate?apikey=' + apikey, json: jsonpayload2, headers: {'content_type': 'application/json'} }, function (e, r, body) { var dns = []; for (var i = 0; i < body.Objects.length; i++) { dns.push({'name': body.Objects[i].Name, 'dn': body.Objects[i].DN}) } callback(null, dns, apikey); }) }, function(dns, apikey, callback){ // console.log(dns) var cb = []; for (var i = 0; i < dns.length; i++) { //Retrieve the credential var jsonpayload3 = {"CredentialPath": dns[i].dn, "Pattern": null, "Recursive": false} console.log(dns[i].dn) request.post({uri: 'http://' + server +'/sdk/credentials/retrieve?apikey=' + apikey, json: jsonpayload3, headers: {'content_type': 'application/json'} }, function (e, r, body) { // console.log(body) cb.push({'cl': body.Classname}) callback(null, cb, apikey); console.log(cb) }); } } ], function (err, result) { // console.log(result) // result now equals 'done' }); Update: I'm building a small application that needs to make multiple HTTP calls to a an external API and amalgamates the results into a single object or array. e.g. Connect to endpoint and get auth key - pass auth key to step 2 Connect to endpoint using auth key and get JSON results - create an object containing summary results and pass to step 3. Iterate over passed object summary results and call API for each item in the object to get detailed information for each summary line Create a single JSON data structure that contains the summary and detail information. The original question below outlines what I've tried so far! Original Question: Will the async.waterfall method support multiple callbacks? i.e. Iterate over an array thats passed from a previous item in the chain, then invoke multiple http requests each of which would have their own callbacks. e.g, sync.waterfall([ function(dns, key, callback){ var cb = []; for (var i = 0; i < dns.length; i++) { //Retrieve the credential var jsonpayload3 = {"Cred": dns[i].DN, "Pattern": null, "Recursive": false} console.log(dns[i].DN) request.post({uri: 'http://' + vedserver +'/api/cred/retrieve?apikey=' + key, json: jsonpayload3, headers: {'content_type': 'application/json'} }, function (e, r, body) { console.log(body) cb.push({'cl': body.Classname}) callback(null, cb, key); }); } }

  • Why and what for: java enum

    - by Mat Banik
    Today I was browsing through some question on this site and I found mention of enum being used in singleton pattern and that there are some thread safety benefits to such solution. I never used enums and I have been programing in java for more than couple a years now. And apparently they changed a lot and now they even do full blown support of OOP within them selfs. Now why and what for should I used enum in day to day programing?

  • Comparing route to current request in Symfony

    - by gruner
    For my site navigation I'd like to indicate the current page. If each page in the navigation has its own route is there a way to see if the current request matches the route? Something like: $request->getRoute() == '@my_route' Or, more generally, is there an idiomatic way of setting the active page when creating site navigation in Symfony?
