The Template Method Design Pattern using C# .Net
- by nijhawan.saurabh
First of all I'll just put this pattern in context and describe its intent as in the GOF book: Template Method: Define the skeleton of an algorithm in an operation, deferring some steps to Subclasses. Template Method lets subclasses redefine certain steps of an algorithm without changing the Algorithm's Structure. Usage: When you are certain about the High Level steps involved in an Algorithm/Work flow you can use the Template Pattern which allows the Base Class to define the Sequence of the Steps but permits the Sub classes to alter the implementation of any/all steps. Example in the .Net framework: The most common example is the Asp.Net Page Life Cycle. The Page Life Cycle has a few methods which are called in a sequence but we have the liberty to modify the functionality of any of the methods by overriding them. Sample implementation of Template Method Pattern: Let's see the class diagram first: Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:8.0pt; mso-para-margin-left:0in; line-height:107%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:1.0pt; mso-ligatures:standard;} And here goes the code:EmailBase.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 public abstract class EmailBase 10 { 11 12 public bool SendEmail() 13 { 14 if (CheckEmailAddress() == true) // Method1 in the sequence 15 { 16 if (ValidateMessage() == true) // Method2 in the sequence 17 { 18 if (SendMail() == true) // Method3 in the sequence 19 { 20 return true; 21 } 22 else 23 { 24 return false; 25 } 26 27 } 28 else 29 { 30 return false; 31 } 32 33 } 34 else 35 { 36 return false; 37 38 } 39 40 41 } 42 43 protected abstract bool CheckEmailAddress(); 44 protected abstract bool ValidateMessage(); 45 protected abstract bool SendMail(); 46 47 48 } 49 } 50 EmailYahoo.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 public class EmailYahoo:EmailBase 10 { 11 12 protected override bool CheckEmailAddress() 13 { 14 Console.WriteLine("Checking Email Address : YahooEmail"); 15 return true; 16 } 17 protected override bool ValidateMessage() 18 { 19 Console.WriteLine("Validating Email Message : YahooEmail"); 20 return true; 21 } 22 23 24 protected override bool SendMail() 25 { 26 Console.WriteLine("Semding Email : YahooEmail"); 27 return true; 28 } 29 30 31 } 32 } 33 EmailGoogle.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 public class EmailGoogle:EmailBase 10 { 11 12 protected override bool CheckEmailAddress() 13 { 14 Console.WriteLine("Checking Email Address : GoogleEmail"); 15 return true; 16 } 17 protected override bool ValidateMessage() 18 { 19 Console.WriteLine("Validating Email Message : GoogleEmail"); 20 return true; 21 } 22 23 24 protected override bool SendMail() 25 { 26 Console.WriteLine("Semding Email : GoogleEmail"); 27 return true; 28 } 29 30 31 } 32 } 33 Program.cs 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace TemplateMethod 8 { 9 class Program 10 { 11 static void Main(string[] args) 12 { 13 Console.WriteLine("Please choose an Email Account to send an Email:"); 14 Console.WriteLine("Choose 1 for Google"); 15 Console.WriteLine("Choose 2 for Yahoo"); 16 string choice = Console.ReadLine(); 17 18 if (choice == "1") 19 { 20 EmailBase email = new EmailGoogle(); // Rather than newing it up here, you may use a factory to do so. 21 email.SendEmail(); 22 23 } 24 if (choice == "2") 25 { 26 EmailBase email = new EmailYahoo(); // Rather than newing it up here, you may use a factory to do so. 27 email.SendEmail(); 28 } 29 } 30 } 31 } 32 Final Words: It's very obvious that why the Template Method Pattern is a popular pattern, everything at last revolves around Algorithms and if you are clear with the steps involved it makes real sense to delegate the duty of implementing the step's functionality to the sub classes. Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:8.0pt; mso-para-margin-left:0in; line-height:107%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:1.0pt; mso-ligatures:standard;}Read the article

Is it a good practice to wrap all primitives and Strings?
- by Amogh Talpallikar
According to Jeff Bay's Essay on Object Callisthenics, One of the practices is set to be "Wrap all primitives and Strings" Can anyone elaborate on this ? In languages where we already have wrappers for primitives like C# and Java. and In languages where Collections can have generics where you are sure of what type goes into the collection, do we need to wrap string's inside their own classes ? Does it have any other advantage ?Read the article

Deserialize inherited classes into the same list in XNA
- by M0rgenstern
I am writing a Gui for a game (for what else ...). Therefor I wrote a class GuiElement which has some serializeable fields. From this class I deflect a Class "Button" which has one serializeable field more. Furthermore, I have a Class GuiWindow, which is as well deflected from "GuiElement". An Object of this Class has a Field "HandledElements" of the type "List". To know the layout of the Menues, I use XML-Files, which look like that (for example): <?xml version="1.0" encoding="utf-8" ?> <XnaContent xmlns:Generic="System.Collections.Generic"> <Asset Type="System.Collections.Generic.List[GUI.GuiWindow]"> <Item> <Position>0 0</Position> <AlternativeImagePath></AlternativeImagePath> <IsActive>true</IsActive> <Name>MainMenu</Name> <HandledElements> <Item> <Position>100 100</Position> <AlternativeImagePath></AlternativeImagePath> <IsActive>true</IsActive> <Name>Optionen</Name> <Caption>Optionen</Caption> </Item> </HandledElements> </Item> <Item> <Position>0 0</Position> <AlternativeImagePath></AlternativeImagePath> <IsActive>false</IsActive> <Name>Options</Name> <HandledElements> </HandledElements> </Item> </Asset> </XnaContent> As you can see, the first window has in its "HandledElements" List an Item with the Field . This is a field which only a Button has. The Problem is now: I can't deserialize this XML file, because GuiElement does not have this Field, it only has the few fields above. I thought it would know automatically which Class to use,but it doesn't. Do I really have to give my windows a list for each child class of GuiElement? Or can I do another workaround?Read the article

mongoDB Management Studio
- by Liam McLennan
This weekend I have been in Sydney at the MS Web Camp, learning about web application development. At the end of the first day we came up with application ideas and pitched them. My idea was to build a web management application for mongoDB. mongoDB I pitched my idea, put down the microphone, and then someone asked, “what’s mongo?”. Good question. MongoDB is a document database that stores JSON style documents. This is a JSON document for a tweet from twitter: db.tweets.find()[0] { "_id" : ObjectId("4bfe4946cfbfb01420000001"), "created_at" : "Thu, 27 May 2010 10:25:46 +0000", "profile_image_url" : "http://a3.twimg.com/profile_images/600304197/Snapshot_2009-07-26_13-12-43_normal.jpg", "from_user" : "drearyclocks", "text" : "Does anyone know who has better coverage, Optus or Vodafone? Telstra is still too expensive.", "to_user_id" : null, "metadata" : { "result_type" : "recent" }, "id" : { "floatApprox" : 14825648892 }, "geo" : null, "from_user_id" : 6825770, "search_term" : "telstra", "iso_language_code" : "en", "source" : "<a href="http://www.tweetdeck.com" rel="nofollow">TweetDeck</a>" } A mongodb server can have many databases, each database has many collections (instead of tables) and a collection has many documents (instead of rows). Development Day 2 of the Sydney MS Web Camp was allocated to building our applications. First thing in the morning I identified the stories that I wanted to implement: Scenario: View databases Scenario: View Collections in a database Scenario: View Documents in a Collection Scenario: Delete a Collection Scenario: Delete a Database Scenario: Delete Documents Over the course of the day the team (3.5 developers) implemented all of the planned stories (except ‘delete a database’) and also implemented the following: Scenario: Create Database Scenario: Create Collection Lessons Learned I’m new to MongoDB and in the past I have only accessed it from Ruby (for my hare-brained scheme). When it came to implementing our MongoDB management studio we discovered that their is no official MongoDB driver for .NET. We chose to use NoRM, honestly just because it was the only one I had heard of. NoRM was a challenge. I think it is a fine library but it is focused on mapping strongly typed objects to MongoDB. For our application we had no prior knowledge of the types that would be in the MongoDB database so NoRM was probably a poor choice. Here are some screens (click to enlarge):Read the article

CAM v2.0 ships – all new foundation version
- by drrwebber
The latest release of the CAM editor toolset is now available on Sourceforge.net – search NIEM. In this all new version the support from Oracle has enabled a transformation of the editor underpinning Java framework and results in 3x performance improvement and 50% better memory utilization. The result of nearly six months of improvements are catalogued in the release notes. http://sourceforge.net/projects/camprocessor/files/CAM%20Editor/Releases/2.0/CAM_Editor_2-0_Release_Notes.pdf/download However here I’d like to talk about the strategic vision and highlight specific new go to features that make a difference for exchange schema designers and with a focus on the NIEM community. So why is this a foundation version? Basically the new drag and drop designer tool allows you to tailor your own dictionary collection of components and then simply select and position those into your resulting exchange structure. This is true global reuse enabled from a canonical domain dictionary collection. So instead of grappling with XSD Schema syntax, or UML model nuances – this is straightforward direct WYSIWYG visual engineering – using familiar sets of business components. Then the toolkit writes the complex XSD Schema for you, along with test samples, documentation, XMI/UML models, Mindmaps and more. So how do you get a set of business components? The toolkit allows you to harvest these from existing schema collections or enterprise data models, or as in the case of NIEM, existing domain dictionary collections. I’ve been using this for the latest IEEE/OASIS/NIST initiative on a Common Data Format (CDF) for elections management systems. So you can download those from OASIS and see how this can transform how you build actual business exchanges – improving the quality, consistency and usability – and dramatically allowing automated generation of artifacts you only dreamed of before – such as a model of your entire major exchange collection components. http://www.oasis-open.org/committees/documents.php?wg_abbrev=election So what we have here is a foundation version – setting the scene and the basis for changing how people can generate and manage information exchanges. A foundation built using the OASIS CAM standard combined with aspects of the NIEM Naming and Design Rules and the UN/CEFACT Core Components specifications and emerging work on OASIS CIQ name and address and ANSI/ISO code list schema. We still have a raft of work to do to integrate this into SOA best practices and extend the dictionary capabilities to assist true community development. Answering questions such as: - How good is my canonical component collection? - How much reuse is really occurring? - What inconsistencies and extensions are there in the dictionary components? Expect us to begin tackling these areas now that the foundation is in place. The immediate need is to develop training and self-start materials – so we will be focusing there for the next couple of months and especially leading up to the IJIS industry event in July in New Jersey, and the NIEM NTE event in August in Philadelphia. http://sourceforge.net/projects/camprocessorRead the article

Stuff I learned at Innovate 2011
- by David Dorf
After returning from the NRF Innovate 2011 conference, I picked up few nuggets I thought I'd share here. These thoughts are a bit random, but I hope they're useful nonetheless.Kevin Kelly opened the conference with six verbs that represent the future. They were Screening, Interacting, Sharing, Accessing, Flowing, and Generating. It struck me that these are all ways in which we merge the digital and physical worlds. The internet of things continues to gain momentum.Some buzzwords: deal economy, subscription commerce, discovery (instead of search), curationThat last one, curation, came up over and over. Retailers, especially those in fashion, are finding value in helping their customers organize and present their own collections. Social media has made sharing such collections easy, and mobile lets them take those ideas into the stores. Mannequins are becoming less relevant.I heard from both HauteLook and Gilt Groupe (flash sale retailers) that a large percentage of their visits come from mobile devices, and most of those are iOS devices. I find it interesting that even though Android has passed iPhone in units shipped (and will eventually pass iOS as a whole), its still the Apple crowd that leads the way.RadioShack mentioned their Holiday Heroes campaigned was very successful. They asked their Foursquare users to check-in at a gym, coffee shop, and transportation hub as part of being a hero. For this feat, customers were awarded a special badge that was worth 20% off at their next store visit. They claim a 3.5x increase in ticket size vs. regular check-in customers, and a 5x increase vs those that don't check-in at all.I also learned of RadioShack's #28 campaign, which is apparently one of the largest Twitter trends ever. Their partnership with LIVESTRONG has gotten them followers, impressions, and credit for supporting the fight against cancer.The guys at Invodo showed the importance of video to e-commerce. They gave compelling examples of how video can show customers the value of products better than just words.The highlight of the show was Guy Kawasaki's talk on innovation, which was not only informative but also peppered with humor and personality. Back in the early days of the internet boom, Guy turned down the CEO position at Yahoo! because the commute was too long. By his calculation, that was a $2B mistake.There are other good accounts of the conference at the NRF Blog.Read the article

Why do camera's aspect ratio look good on computer but not on Android devices?
- by Pooya Fayyaz
I'm developing a game for Android devices and I have a script that solves the aspect-ratio problem for computer screens but not for my intended target platform. It looks perfect on computer, even when re-sizing the game screen, but not when running my game in landscape mode on mobile phones. This is my script using UnityEngine; using System.Collections; using System.Collections.Generic; public class reso : MonoBehaviour { void Update() { // set the desired aspect ratio (the values in this example are // hard-coded for 16:9, but you could make them into public // variables instead so you can set them at design time) float targetaspect = 16.0f / 9.0f; // determine the game window's current aspect ratio float windowaspect = (float)Screen.width / (float)Screen.height; // current viewport height should be scaled by this amount float scaleheight = windowaspect / targetaspect; // obtain camera component so we can modify its viewport Camera camera = GetComponent<Camera>(); // if scaled height is less than current height, add letterbox if (scaleheight < 1.0f && Screen.width <= 490 ) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } else // add pillarbox { float scalewidth = 1.0f / scaleheight; Rect rect = camera.rect; rect.width = scalewidth; rect.height = 1.0f; rect.x = (1.0f - scalewidth) / 2.0f; rect.y = 0; camera.rect = rect; } } } I figured that my problem occurs in this part of the script: if (scaleheight < 1.0f) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } Its look like this on my mobile phone (portrait): and on landscape mode:Read the article

How to make an object move again after being stopped by collision in Unity?
- by Matthew Underwood
I have a player object which position is always centered on the main camera's viewport. This object has a Rigidbody 2D, a box and circle collider. The player moves around a level, the level has a polygon collider attached. I move the camera until the object hits against the collider, which stops the movement of the camera by setting its speed to 0. The problem happens when I want to move the camera / player object away from the collider. As the speed is already at 0, it cannot move away from the collider. The script attached to the player object, checks for collisions and applies the speed to 0 on the main camera's test script. using UnityEngine; using System.Collections; public class move : MonoBehaviour { public float speed; public test testing; // Use this for initialization void Start () { speed = 10F; testing = Camera.main.GetComponent<test>(); } // Update is called once per frame void FixedUpdate () { Vector3 p = Camera.main.ViewportToWorldPoint(new Vector3(0.5F, 0.5F, Camera.main.nearClipPlane)); transform.position = new Vector3(p.x, p.y, -1); } void OnCollisionEnter2D(Collision2D col) { testing.speed = 0; } void OnCollisionExit2D(Collision2D col) { testing.speed = 10F; } } This is the script attached to the main camera; just a simple script that changes the camera's position. using UnityEngine; using System.Collections; public class test : MonoBehaviour { public float speed; public float translationY; public float translationX; // Use this for initialization void Start () { speed = 10F; } void FixedUpdate () { translationY = Input.GetAxis("Vertical") * speed * Time.deltaTime; translationX = Input.GetAxis("Horizontal") * speed * Time.deltaTime; transform.Translate(translationX, translationY, 0); } } The player object isn't kinematic and is a fixed angle, the colliders aren't triggers and the polygon collider isn't a trigger either. The player is the red square, the collider is the pink area. -- EDIT -- From the latest change the collider set up for the player So if the X speed was disabled. It wouldnt move into the side of the polygon colider which is good, but yet you couldnt move away from it. And moving down would move inside the colider.Read the article
