  • Is dependency injection by hand a better alternative to composition and polymorphism?

    - by Drake Clarris
    First, I'm an entry level programmer; In fact, I'm finishing an A.S. degree with a final capstone project over the summer. In my new job, when there isn't some project for me to do (they're waiting to fill the team with more new hires), I've been given books to read and learn from while I wait - some textbooks, others not so much (like Code Complete). After going through these books, I've turned to the internet to learn as much as possible, and started learning about SOLID and DI (we talked some about Liskov's substitution principle, but not much else SOLID ideas). So as I've learned, I sat down to do to learn better, and began writing some code to utilize DI by hand (there are no DI frameworks on the development computers). Thing is, as I do it, I notice it feels familiar... and it seems like it is very much like work I've done in the past using composition of abstract classes using polymorphism. Am I missing a bigger picture here? Is there something about DI (at least by hand) that goes beyond that? I understand the possibility of having configurations not in code of some DI frameworks having some great benefits as far as changing things without having to recompile, but when doing it by hand, I'm not sure if it's any different than stated above... Some insight into this would be very helpful!

  • Is there a better way to organize my module tests that avoids an explosion of new source files?

    - by luser droog
    I've got a neat (so I thought) way of having each of my modules produce a unit-test executable if compiled with the -DTESTMODULE flag. This flag guards a main() function that can access all static data and functions in the module, without #including a C file. From the README: -- Modules -- The various modules were written and tested separately before being coupled together to achieve the necessary basic functionality. Each module retains its unit-test, its main() function, guarded by #ifdef TESTMODULE. `make test` will compile and execute all the unit tests, producing copious output, but importantly exitting with an appropriate success or failure code, so the `make test` command will fail if any of the tests fail. Module TOC __________ test obj src header structures CONSTANTS ---- --- --- --- -------------------- m m.o m.c m.h mfile mtab TABSZ s s.o s.c s.h stack STACKSEGSZ v v.o v.c v.h saverec_ f.o f.c f.h file ob ob.o ob.c ob.h object ar ar.o ar.c ar.h array st st.o st.c st.h string di di.o di.c di.h dichead dictionary nm nm.o nm.c nm.h name gc gc.o gc.c gc.h garbage collector itp itp.c itp.h context osunix.o osunix.c osunix.h unix-dependent functions It's compile by a tricky bit of makefile, m:m.c ob.h ob.o err.o $(CORE) itp.o $(OP) cc $(CFLAGS) -DTESTMODULE $(LDLIBS) -o $@ $< err.o ob.o s.o ar.o st.o v.o di.o gc.o nm.o itp.o $(OP) f.o where the module is compiled with its own C file plus every other object file except itself. But it's creating difficulties for the kindly programmer who offered to write the Autotools files for me. So the obvious way to make it "less weird" would be to bust-out all the main functions into separate source files. But, but ... Do I gotta?

  • NHibernate - joining on a subquery using ICriteria

    - by owensymes.mp
    I have a SQL query that I need to represent using NHibernate's ICriteria API. SELECT u.Id as Id, u.Login as Login, u.FirstName as FirstName, u.LastName as LastName, gm.UserGroupId_FK as UserGroupId, inner.Data1, inner.Data2, inner.Data3 FROM dbo.User u inner join dbo.GroupMember gm on u.Id = gm.UserAnchorId_FK left join ( SELECT di.UserAnchorId_FK, sum(di.Data1) as Data1, sum(di.Data2) as Data2, sum(di.Data3) as Data3 FROM dbo.DailyInfo di WHERE di.Date between '2009-04-01' and '2009-06-01' GROUP BY di.UserAnchorId_FK ) inner ON inner.UserAnchorId_FK = u.Id WHERE gm.UserGroupId_FK = 195 Attempts so far have included mapping 'User' and 'DailyInfo' classes (my entities) and making a DailyInfo object a property of the User object. However, how to map the foreign key relationship between them is still a mystery, ie <one-to-one></one-to-one> <one-to-many></one-to-many> <generator class="foreign"><param name="property">Id</param></generator> (!) Solutions on the web are generally to do with subqueries within a WHERE clause, however I need to left join on this subquery instead to ensure NULL values are returned for rows that do not join. I have the feeling that I should be using a Criteria for the outer query, then forming a 'join' with a DetachedCriteria to represent the subquery?

  • Error Connecting to Oracle Database from Pentaho Report Designer

    - by knt
    Hi all, I am new to Pentaho, and I am struggling to set up a new database connection. I am trying to connect to an Oracle 10g database, but whenever I test the connection, I get the below error. It doesn't really seem to list any specific error message so I'm not really sure what to do or where to go from this point. I placed ojdbc jar's in my tomcat lib folder, but maybe there is another place those should go. Any help/hints would be greatly appreciated.

  • How to use NInject (or other DI / IoC container) with the model binder in ASP.NET MVC 2 ?

    - by Andrei Rinea
    Let's say I have an User entity and I would want to set it's CreationTime property in the constructor to DateTime.Now. But being a unit test adopter I don't want to access DateTime.Now directly but use an ITimeProvider : public class User { public User(ITimeProvider timeProvider) { // ... this.CreationTime = timeProvider.Now; } // ..... } public interface ITimeProvider { public DateTime Now { get; } } public class TimeProvider : ITimeProvider { public DateTime Now { get { return DateTime.Now; } } } I am using NInject 2 in my ASP.NET MVC 2.0 application. I have a UserController and two Create methods (one for GET and one for POST). The one for GET is straight forward but the one for POST is not so straight and not so forward :P because I need to mess with the model binder to tell it to get a reference of an implementation of ITimeProvider in order to be able to construct an user instance. public class UserController : Controller { [HttpGet] public ViewResult Create() { return View(); } [HttpPost] public ActionResult Create(User user) { // ... } } I would also like to be able to keep all the features of the default model binder. Any chance to solve this simple/elegant/etc? :D

  • How to use EJB 3.1 DI in Servlet ? (Could not inject session bean by @EJB from web application)

    - by kislo_metal
    I am tying to merging web application(gwt, jpa) to an separate 2 application(business login in ejb/jpa and web client in gwt). Currently i can`t inject my beans from web application (simple servlet) I am using glassfish v3. module limbo(ejb jar) is in dependency of module lust (war). If I use lust with compiler output of limbo everything work perfect (if ejb in web application and the are deploying together as one application). Have I messed some container configuration ?

  • is right to implement a business logic in the type binding DI framwork?

    - by Martino
    public IRedirect FactoryStrategyRedirect() { if (_PasswordExpired) { return _UpdatePasswordRedirectorFactory.Create(); } else { return _DefaultRedirectorFactory.Create(); } } This strategy factory method can be replaced with type binding and when clause: Bind<IRedirect>.To<UpdatePasswordRedirector>.When(c=> c.kernel.get<SomeContext>().PasswordExpired()) Bind<IRedirect>.To<DefaultRedirector>.When(c=> not c.kernel.get<SomeContext>().PasswordExpired()) I wonder which of the two approaches is the more correct. What are the pros and cons. Especially in the case in which the logic is more complex with more variables to test and more concrete classes to return. is right to implement a business logic in the binding?

  • Stereo images rectification and disparity: which algorithms?

    - by alessandro.francesconi
    I'm trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted images plus their depth information by looking at their disparity. Actually I've found lots of papers about these two methods, like: "Computing Rectifying Homographies for Stereo Vision" (Zhang - seems one of the best for rectification only) "Three-step image recti?cation" (Monasse) "Rectification and Disparity" (slideshow by Navab) "A fast area-based stereo matching algorithm" (Di Stefano - seems a bit inaccurate) "Computing Visual Correspondence with Occlusions via Graph Cuts" (Kolmogorov - this one produces a very good disparity map, with also occlusion informations, but is it efficient?) "Dense Disparity Map Estimation Respecting Image Discontinuities" (Alvarez - toooo long for a first review) Anyone could please give me some advices for orienting into this wide topic? What kind of algorithm/method should I treat first, considering that I'll work on a very simple input: a pair of left and right images and nothing else, no more information (some papers are based on additional, pre-taken, calibration infos)? Speaking about working implementations, the only interesting results I've seen so far belongs to this piece of software, but only for automatic rectification, not disparity: http://stereo.jpn.org/eng/stphmkr/index.html I tried the "auto-adjustment" feature and seems really effective. Too bad there is no source code...

  • C++ Printing: Printer jams, what am I doing wrong?

    - by Kleas
    I have a problem with printing in C++. As far as I know, this code used to work on my previous printer, but ever since I got another one (an HP C7280) it started giving problems. Whenever I try to print anything, even an empty page, the page JAMS the printer. I have to manualy remove the page from the printer. I have no clue why this is happening. Am I doing something wrong, is it a driver problem, are there better ways to print in C++? I am using Windows 7 64 bit, but this problem also presented itself when I was using Windows Vista 64 bit. I use the following code: PRINTDLG pd; ZeroMemory(&pd, sizeof(pd)); pd.lStructSize = sizeof(pd); pd.hwndOwner = mainWindow; pd.hDevMode = NULL; pd.hDevNames = NULL; pd.Flags = PD_USEDEVMODECOPIESANDCOLLATE | PD_RETURNDC; pd.nCopies = 1; pd.nMinPage = 1; pd.nMaxPage = 0xFFFF; if (PrintDlg(&pd)==TRUE) { DOCINFO di; di.cbSize = sizeof(DOCINFO); di.lpszDocName = "Rumitec en Roblaco Print"; di.lpszOutput = (LPTSTR)NULL; di.fwType = 0; // Start printing StartDoc(pd.hDC, &di); StartPage(pd.hDC); initPrinter(pd.hDC); // ... // Do some drawing // ... // End printing EndPage(pd.hDC); EndDoc(pd.hDC); DeleteDC(pd.hDC); } Am I doing something wrong? Alternatively, is there a better, easier, more modern way to do it?

  • Fluent NHibernate Mapping and Formulas/DatePart

    - by Alessandro Di Lello
    Hi There, i have a very simple table with a Datetime column and i have this mapping in my domain object. MyDate is the name of the datetime column in the DB. public virtual int Day { get; set; } public virtual int Month { get; set; } public virtual int Year { get; set; } public virtual int Hour { get; set; } public virtual int Minutes { get; set; } public virtual int Seconds { get;set; } public virtual int WeekNo { get; set; } Map(x => x.Day).Formula("DATEPART(day, Datetime)"); Map(x => x.Month).Formula("DATEPART(month, Datetime)"); Map(x => x.Year).Formula("DATEPART(year, Datetime)"); Map(x => x.Hour).Formula("DATEPART(hour, Datetime)"); Map(x => x.Minutes).Formula("DATEPART(minute, Datetime)"); Map(x => x.Seconds).Formula("DATEPART(second, Datetime)"); Map(x => x.WeekNo).Formula("DATEPART(week, Datetime)"); This is working all great .... but Week Datepart. I saw with NHProf the sql generating for a select and here's the problem it's generating all the sql correctly but for week datepart.. this is part of the SQL generated: ....Datepart(day, MyDate) ... ....Datepart(month, MyDate) ... ....Datepart(year, MyDate) ... ....Datepart(hour, MyDate) ... ....Datepart(minute, MyDate) ... ....Datepart(second, MyDate) ... ....Datepart(this_.week, MyDate) ... where this_ is the alias for the table that nhibernate uses. so it's treating the week keyword for the datepart stuff as a column or something like that. To clarify there's no column or properties that is called week. some help ? cheers Alessandro

  • WCF Webservices and FaultContract - Client's receiving SoapExc insted of FaultException<TDetails>

    - by Alessandro Di Lello
    Hi All, i'm developing a WCF Webservice and consuming it within a mvc2 application. My problem is that i'm using FaultContracts on my methods with a custom FaultDetail and i'm throwing manyally the faultexception but when the client receive the exception , it receives a normal SoapException instead of my FaultException that i throwed from the service side. Here is some code: Custom Fault Detail Class: [DataContract] public class MyFaultDetails { [DataMember] public string Message { get; set; } } Operation on service contract: [OperationContract] [FaultContract(typeof(MyFaultDetails))] void ThrowException(); Implementation: public void ThrowException() { var details = new MyFaultDetails { Message = "Exception Test" }; throw new FaultException<MyFaultDetails >(details , new FaultReason(details .Message), new FaultCode("MyFault")); } Client side: try { // Obv proxy init etc.. service.ThrowException(); } catch (FaultException<MyFaultDetails> ex) { // stuff } catch (Exception ex) { // stuff } What i expect is to catch the FaultException , instead that catch is skipped and the next catch is taken with an exception of type SoapException. Am i missing something ? i red a lot of threads about using faultcontracts within wcf and what i did seems to be good. I had a look at the wsdl and xsd generated and they look fine. here's a snippet regarding this method: <wsdl:operation name="ThrowException"> <wsdl:input wsaw:Action="http://tempuri.org/IAnyJobService/ThrowException" message="tns:IAnyJobService_ThrowException_InputMessage" /> <wsdl:output wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionResponse" message="tns:IAnyJobService_ThrowException_OutputMessage" /> <wsdl:fault wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionAnyJobServiceFaultExceptionFault" name="AnyJobServiceFaultExceptionFault" message="tns:IAnyJobService_ThrowException_AnyJobServiceFaultExceptionFault_FaultMessage" /> </wsdl:operation> <wsdl:operation name="ThrowException"> <soap:operation soapAction="http://tempuri.org/IAnyJobService/ThrowException" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> <wsdl:fault name="AnyJobServiceFaultExceptionFault"> <soap:fault use="literal" name="AnyJobServiceFaultExceptionFault" namespace="" /> </wsdl:fault> </wsdl:operation> Any help ?

  • Reasoner Conversion Problems:

    I have this code right here in Java and I wanted to translate it in C++, but I had some problems going: this is the java code: import java.io.*; import java.util.*; public class ClueReasoner { private int numPlayers; private int playerNum; private int numCards; private SATSolver solver; private String caseFile = "cf"; private String[] players = {"sc", "mu", "wh", "gr", "pe", "pl"}; private String[] suspects = {"mu", "pl", "gr", "pe", "sc", "wh"}; private String[] weapons = {"kn", "ca", "re", "ro", "pi", "wr"}; private String[] rooms = {"ha", "lo", "di", "ki", "ba", "co", "bi", "li", "st"}; private String[] cards; public ClueReasoner() { numPlayers = players.length; // Initialize card info cards = new String[suspects.length + weapons.length + rooms.length]; int i = 0; for (String card : suspects) cards[i++] = card; for (String card : weapons) cards[i++] = card; for (String card : rooms) cards[i++] = card; numCards = i; // Initialize solver solver = new SATSolver(); addInitialClauses(); } private int getPlayerNum(String player) { if (player.equals(caseFile)) return numPlayers; for (int i = 0; i < numPlayers; i++) if (player.equals(players[i])) return i; System.out.println("Illegal player: " + player); return -1; } private int getCardNum(String card) { for (int i = 0; i < numCards; i++) if (card.equals(cards[i])) return i; System.out.println("Illegal card: " + card); return -1; } private int getPairNum(String player, String card) { return getPairNum(getPlayerNum(player), getCardNum(card)); } private int getPairNum(int playerNum, int cardNum) { return playerNum * numCards + cardNum + 1; } public void addInitialClauses() { // TO BE IMPLEMENTED AS AN EXERCISE // Each card is in at least one place (including case file). for (int c = 0; c < numCards; c++) { int[] clause = new int[numPlayers + 1]; for (int p = 0; p <= numPlayers; p++) clause[p] = getPairNum(p, c); solver.addClause(clause); } // If a card is one place, it cannot be in another place. // At least one card of each category is in the case file. // No two cards in each category can both be in the case file. } public void hand(String player, String[] cards) { playerNum = getPlayerNum(player); // TO BE IMPLEMENTED AS AN EXERCISE } public void suggest(String suggester, String card1, String card2, String card3, String refuter, String cardShown) { // TO BE IMPLEMENTED AS AN EXERCISE } public void accuse(String accuser, String card1, String card2, String card3, boolean isCorrect) { // TO BE IMPLEMENTED AS AN EXERCISE } public int query(String player, String card) { return solver.testLiteral(getPairNum(player, card)); } public String queryString(int returnCode) { if (returnCode == SATSolver.TRUE) return "Y"; else if (returnCode == SATSolver.FALSE) return "n"; else return "-"; } public void printNotepad() { PrintStream out = System.out; for (String player : players) out.print("\t" + player); out.println("\t" + caseFile); for (String card : cards) { out.print(card + "\t"); for (String player : players) out.print(queryString(query(player, card)) + "\t"); out.println(queryString(query(caseFile, card))); } } public static void main(String[] args) { ClueReasoner cr = new ClueReasoner(); String[] myCards = {"wh", "li", "st"}; cr.hand("sc", myCards); cr.suggest("sc", "sc", "ro", "lo", "mu", "sc"); cr.suggest("mu", "pe", "pi", "di", "pe", null); cr.suggest("wh", "mu", "re", "ba", "pe", null); cr.suggest("gr", "wh", "kn", "ba", "pl", null); cr.suggest("pe", "gr", "ca", "di", "wh", null); cr.suggest("pl", "wh", "wr", "st", "sc", "wh"); cr.suggest("sc", "pl", "ro", "co", "mu", "pl"); cr.suggest("mu", "pe", "ro", "ba", "wh", null); cr.suggest("wh", "mu", "ca", "st", "gr", null); cr.suggest("gr", "pe", "kn", "di", "pe", null); cr.suggest("pe", "mu", "pi", "di", "pl", null); cr.suggest("pl", "gr", "kn", "co", "wh", null); cr.suggest("sc", "pe", "kn", "lo", "mu", "lo"); cr.suggest("mu", "pe", "kn", "di", "wh", null); cr.suggest("wh", "pe", "wr", "ha", "gr", null); cr.suggest("gr", "wh", "pi", "co", "pl", null); cr.suggest("pe", "sc", "pi", "ha", "mu", null); cr.suggest("pl", "pe", "pi", "ba", null, null); cr.suggest("sc", "wh", "pi", "ha", "pe", "ha"); cr.suggest("wh", "pe", "pi", "ha", "pe", null); cr.suggest("pe", "pe", "pi", "ha", null, null); cr.suggest("sc", "gr", "pi", "st", "wh", "gr"); cr.suggest("mu", "pe", "pi", "ba", "pl", null); cr.suggest("wh", "pe", "pi", "st", "sc", "st"); cr.suggest("gr", "wh", "pi", "st", "sc", "wh"); cr.suggest("pe", "wh", "pi", "st", "sc", "wh"); cr.suggest("pl", "pe", "pi", "ki", "gr", null); cr.printNotepad(); cr.accuse("sc", "pe", "pi", "bi", true); } } how can I convert this?

  • MySQL + MyISAM table size question

    - by alessandro ferrucci
    Hello, I have a test table. The test table is as follows: CREATE TABLE mytest ( num1 int(10) unsigned NOT NULL, KEY key1 (num1) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; I inserted 50 million rows in this table. When I do show table status the avg_row_length is 7. I was expecting to see 4 since mySQL uses 4 bytes for integers. Does the key have an effect on the avg_row_length? When I look at my .MYD file the size is 334 MB which is exactly what it should be given that the avg_row_length is 7, however I was really expecting to see 190 MB given that I only have an int. +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | mytest | MyISAM | 10 | Fixed | 50000000 | 7 | 350000000 | 1970324836974591 | 600518656 | 0 | NULL | 2010-05-22 09:15:06 | 2010-05-22 19:32:53 | NULL | latin1_swedish_ci | NULL | | | I have included the output of show table status for mytest table. Sorry about the formatting :D Thanks in advance! Alessandro Ferrucci
