  • creative way for implementing Data object with its corresponding business logic class in java

    - by ekeren
    I have a class that need to be serialized (for both persistentcy and client-server communication) for simplicity's sake let's call the classes Business a BusinessData and I prefix for their Interfaces. All the getter and setter are delegated from Business class to BusinessData class. I thought about implementing IBusinessData interface that will contain all the getter and setters and IBusiness interface that will extend it. I can either make Business extend BuisnessData so I will not need to implement all getter and setter delegates, or make some abstract class ForwardingBusinessData that will only delegate getter and setters. Any of the above option I lose my hierarchy freedom, do any of you have any creative solutions for this problem... I also reviewed DAO pattern: http://java.sun.com/blueprints/patterns/DAO.html

  • Object Oriented Programming Problem

    - by Danny Love
    I'm designing a little CMS using PHP whilst putting OOP into practice. I've hit a problem though. I have a page class, whos constructor accepts a UID and a slug. This is then used to set the properties (unless the page don't exist in which case it would fail). Anyway, I wanted to implement a function to create a page, and I thought ... what's the best way to do this without overloading the constructor. What would the correct way, or more conventional method, of doing this be? My code is below: <?php class Page { private $dbc; private $title; private $description; private $image; private $tags; private $owner; private $timestamp; private $views; public function __construct($uid, $slug) { } public function getTitle() { return $this->title; } public function getDescription() { if($this->description != NULL) { return $this->description; } else { return false; } } public function getImage() { if($this->image != NULL) { return $this->image; } else { return false; } } public function getTags() { if($this->tags != NULL) { return $this->tags; } else { return false; } } public function getOwner() { return $this->owner; } public function getTimestamp() { return $this->timestamp; } public function getViews() { return $this->views; } public function createPage() { // Stuck? } }

    - by Arto Uusikangas
    require 'sketchup' entities = Sketchup.active_model.entities summa = Hash.new for face in entities next unless face.kind_of? Sketchup::Face if (face.material) summa[face.material.display_name] += face.area end end Im trying to get the structure in the array as such: summa { "Bricks" = 500, "Planks" = 4000 } Making a ruby script for Google Sketchup btw But if I run this code i only get Error: #+' for nil:NilClass> C:\Program Files (x86)\Google\Google SketchUp 7\Plugins\test.rb:17 C:\Program Files (x86)\Google\Google SketchUp 7\Plugins\test.rb:14:ineach' C:\Program Files (x86)\Google\Google SketchUp 7\Plugins\test.rb:14 C:\Program Files (x86)\Google\Google SketchUp 7\Plugins\test.rb:8:in `call' As im used to using PHP and just doing $array['myownassoc'] += bignumber; But i guess this isnt the right approach when using Ruby? So any help in how i need to go would be nice.

  • Exception "Illegal attempt to associate a collection with two open sessions" when saving object

    - by Alex
    I am using CastleProject ActiveRecord and I use lazy load feature of this ORM. In order to make lazy load work, it is required to create SessionScope. I do this in Program.cs: public static SessionScope sessionScope; private static void InitializeActiveRecord() { ActiveRecordStarter.Initialize(); sessionScope = new SessionScope(); } This works fine for loading, however, when I try to save my objects, I get an exception saying "Illegal attempt to associate a collection with two open sessions". I guess this is due to the fact that I created one session myself. How to avoid this exception?

  • Position of object in database

    - by fl00r
    Hi! I have got model Team and I've got (i.e.) team = Team.first :offset => 20. Now I need to get number of position of my team in db table. I can do it in ruby: Team.all.index team #=> 20 But I am sure that I can write it on SQL and it will be less expensive for me with big tables.

  • Objective-C: when does an assigned object get deallocated

    - by Stefan Klumpp
    If I have a instance method and within this method I do something like this: NSString *peopleString = [peopleList componentsJoinedByString: @", "]; ... UILabel *likeLabel = [[UILabel alloc] initWithFrame:CGRectMake(16.0+6.0f, 4.0f, 252.0f, 12.0f)]; [likeLabel setText:peopleString]; [likeLabel setFont:[UIFont fontWithName:@"Arial" size:12]]; [likeRow addSubview:likeLabel]; [likeLabel release]; The componentsJoinedByString doesn't contain a new, copy or alloc, thus I don't have to release it. What I'm wondering though is, when my peopleString gets deallocated. Might it happen to early? Meaning, before I can set the text in my label. Should I better use a [[NSString alloc] initWithString:[peopleList componentsJoinedByString: @", "]]; and release it at the end of this method?

  • C# - Rollback SqlTransaction in catch block - Problem with object accessability

    - by Marks
    Hi there. I've got a problem, and all articles or examples i found seem to not care about it. I want to do some database actions in a transaction. What i want to do is very similar to most examples: using (SqlConnection Conn = new SqlConnection(_ConnectionString)) { try { Conn.Open(); SqlTransaction Trans = Conn.BeginTransaction(); using (SqlCommand Com = new SqlCommand(ComText, Conn)) { /* DB work */ } } catch (Exception Ex) { Trans.Rollback(); return -1; } } But the problem is, that the SqlTransaction Trans is declared inside the try block. So it is not accessable in the catch() block. Most examples just do Conn.Open() and Conn.BeginTransaction() before the try block. But i think thats a bit risky, since both can throw multiple exceptions. Am I wrong, or do most people just ignore this risk? Whats the best solution to be able to rollback, if an exception happens. Thanks in advance, Marks

  • Convert a "by" object to a data frame in R

    - by lorin
    I'm using the "by" function in R to chop up a data frame and apply a function to different parts, like this: pairwise.compare <- function(x) { Nright <- ... Nwrong <- ... Ntied <- ... return(c(Nright=Nright, Nwrong=Nwrong, Ntied=Ntied)) } Z.by <- by(rankings, INDICES=list(rankings$Rater, rankings$Class), FUN=pairwise.compare) The result (Z.by) looks something like this: : 4 : 357 Nright Nwrong Ntied 3 0 0 ------------------------------------------------------------ : 8 : 357 NULL ------------------------------------------------------------ : 10 : 470 Nright Nwrong Ntied 3 4 1 ------------------------------------------------------------ : 11 : 470 Nright Nwrong Ntied 12 4 1 What I would like is to have this result converted into a data frame (with the NULL entries not present) so it looks like this: Rater Class Nright Nwrong Ntied 1 4 357 3 0 0 2 10 470 3 4 1 3 11 470 12 4 1 How do I do that?

  • Setting date from selectInputDate to object

    - by DD
    I have a date controller which does various things. Once a calendar date is set, I want to pass the value from the date controller to another bean. The problem I have is that the setPropertyActionListener gets called before the user clicks on a date. Is there a way to get the date from the selectInputDate after selection and pass to a bean? This is what I tried: <ice:selectInputDate popupDateFormat="dd-MMM-yyyy" renderAsPopup="true" value="#{dateRangeDateContoller.end}" > <f:setPropertyActionListener target="#{searchParameters.endDate}" value="#{dateRangeDateContoller.end}" /> </ice:selectInputDate>

  • Comparing Object properties using reflection

    - by Kumar
    I have two classes Address and Employee as follows: public class Address { public string AddressLine1 { get; set; } public string AddressLine2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { public string FirstName { get; set; } public string MiddleName { get; set; } public string LastName { get; set; } public Address EmployeeAddress { get; set; } } I have two employee instances as follows: var emp1Address = new Address(); emp1Address.AddressLine1 = "Microsoft Corporation"; emp1Address.AddressLine2 = "One Microsoft Way"; emp1Address.City = "Redmond"; emp1Address.State = "WA"; emp1Address.Zip = "98052-6399"; var emp1 = new Employee(); emp1.FirstName = "Bill"; emp1.LastName = "Gates"; emp1.EmployeeAddress = emp1Address; var emp2Address = new Address(); emp2Address.AddressLine1 = "Gates Foundation"; emp2Address.AddressLine2 = "One Microsoft Way"; emp2Address.City = "Redmond"; emp2Address.State = "WA"; emp2Address.Zip = "98052-6399"; var emp2 = new Employee(); emp2.FirstName = "Melinda"; emp2.LastName = "Gates"; emp2.EmployeeAddress = emp2Address; Now how can I write a method which compares these two employees and returns the list of properties which have different values. So in this example I would like the result to be FirstName and Address.AddressLine1 .

  • JavaFX MouseEvent continues when I remove the object it happened on

    - by Kyle
    It took me a while to realize what was going on with mouse events going through my blocking dialog boxes when I closed them, but I finally figured out why. I still don't know any good way to fix it. I have a custom dialog box (that blocks the mouse) with a close button. When I click the close button, I remove the dialog box from the scene, but JavaFx is still processing the MouseEvent and now it finds that there is nothing blocking the screen behind where the cancel button was, so that component receives a MouseEvent. How do I make the mouseEvent stop processing when I see that they pressed cancel and remove the dialog box? Or, is there a way to make the removing of the dialog box not happen until after it is done processing the MouseEvent? Example Code for the problem: import javafx.stage.Stage; import javafx.scene.Scene; import javafx.scene.shape.Rectangle; import javafx.scene.input.MouseEvent; import javafx.scene.control.Button; var theScene:Scene; var btn:Button; Stage { title: "Application title" scene: theScene= Scene { width: 500 height: 200 content: [ Rectangle{ width: bind theScene.width height: bind theScene.height onMouseClicked: function(e:MouseEvent):Void{ println("Rectangle");} }, Button{ layoutX: 20 layoutY: 50 blocksMouse: true text: "JustPrint" action:function():Void{ println("JustPrint");} }, btn = Button{ layoutX: 20 layoutY: 20 blocksMouse: true text: "Cancel" action:function():Void{ println("Cancel"); delete btn from theScene.content;} }, ] } } When you press "JustPrint" you get: JustPrint When you press "Cancel" you get: Cancel Rectangle
