  • In Eclipse, how do I change the default modifiers in the class/type template?

    - by gustafc
    Eclipse's default template for new types (Window Preferences Code Style Code Templates New Java Files) looks like this: ${filecomment} ${package_declaration} ${typecomment} ${type_declaration} Creating a new class, it'll look something like this: package pkg; import blah.blah; public class FileName { // Class is accessible to everyone, and can be inherited } Now, I'm fervent in my belief that access should be as restricted as possible, and inheritance should be forbidden unless explicitly permitted, so I'd like to change the ${type_declaration} to declare all classes as final rather than public: package pkg; import blah.blah; final class FileName { // Class is only accessible in package, and can't be inherited } That seems easier said than done. The only thing I've found googling is a 2004 question on Eclipse's mailing list which was unanswered. So, the question in short: How can I change the default class/type modifiers in Eclipse? I'm using Eclipse Galileo (3.5) if that matters.

  • How to call javascript function when url variable is sent

    - by mattlarkin
    Hello, heres basically what I need to get done. I have a jsp page which allows me to add/modify/delete an item. The items are stored in a database which I have controller classes to access(dont worry bout that part) When an item gets selected and deleted the id of the item gets sent to the controller to be processed. The item will not always be deleted if their is a foreign key constraint so I send either a delete=true or delete=false through url back to the jsp page. I would like to have it so a javascript function gets called displaying an alert saying the item was deleted or the item was not deleted. can someone please tell me the best way to do this? thank you

  • VB.NET Abstract Property

    - by ElPresidente
    I have an abstract "GridBase" class with two types of derived classes "DetailGrid" and "HeaderGrid". Respectively, one is comprised of "DetailRow" objects and the other "HeaderRow" objects. Both of those inherit from a "RowBase" abstract class. What I am trying to do is the following: Public MustInherit Class GridBase Private pRows As List(Of RowBase) Public ReadOnly Property Rows As List(Of RowBase) Get Return pRows End Get End Property End Class Public Class DetailGrid Inherits GridBase End Class In this scenario, I want DetailGrid.Rows to return a list of DetailRow. I want HeaderRow.Rows to return a list of HeaderRow. Am I on the right track with this or should the Rows property not be included in the GridBase class?

  • CakePHP Form Helper - Show error class, but not error message

    - by Jeremy Penrod
    I'm attempting to customize the error output on the CakePHP 2.0 form helper. Currently, the form renders error messages below the input and applies an 'error' class to the input's label. I have found that I can either disable error reporting altogether for an input, or output the error class and message. I would like the error class to be applied to the label of the offending inputs WITHOUT any message below. How do you turn off the error message outputting for a form, BUT still apply error classes to offending labels?

  • Java combine parents of two large inheritance chains

    - by Soylent Green
    I have two parent classes in a huge project, let's say ClassA and ClassB. Each class has many subclasses, which in turn have many subclasses, which in turn have many subclasses, etc. My task is to "marry" these two "families" so that both inherit from a SINGLE parent. I need to essentially make ClassA and ClassB one class (parent) to both of their combined subclasses (children). ClassA and ClassB both currently implement Serializable. I am currently trying to make both inheritance chains inherit from ClassA, and then copy all functions and data members from ClassB into ClassA. This is tedious, and I think a terrible solution. What would be the CORRECT way to solve this problem?

  • Elegant way to add functionallity to previously defined functions

    - by Bastiaan
    How to combine two functions together I have a class controlling some hardware: class Heater() def set_power(self,dutycycle, period) ... def turn_on(self) ... def turn_off(self) And a class that connects to a database and handles all data logging fuctionallity for an experiment: class DataLogger() def __init__(self) # Record measurements and controls in a database def start(self,t) # Starts a new thread to aqcuire and reccord measuements every t secconds Now, in my program recipe.py I want to do something like: log = DataLogger() @DataLogger_decorator H1 = Heater() log.start(60) H1.set_power(10,100) H1.turn_on() sleep(10) H1.turn_off() etc Where all actions on H1 are recorded by the datalogger. I can change any of the classes involved, just looking for an elegant way to do this. Ideally the hardware functions remain separated from the database and DataLogger functions. And ideally the DataLogger is reusable for other controls and measurements.

  • How to hide/show div using jQuery without altering dimensions?

    - by Byron S
    I have a div that is holding a google chart: <div id="chart_div" style="width: 600px; height: 300px;"></div> It has one CSS property: display: none. On the click of a button, I would like to have the chart be displayed using jQuery hide() and show(). It's working, however, the chart's dimensions are set to something different than I have specified and refuse to change to what I have specified. Here is my jquery code: $(document).ready(function(){ var chart = $('#chart_div'); $('#submit').click(function(){ chart.show('slow'); }); }); Let me know if theres any more code you would like to see. By the way, the chart div is not being contained in anything else so that isn't the problem.

  • What features can I use during log in/out

    - by thecoshman
    I know that this question is going to be painfully vague, but here it is any way. I have made an small console application designed to be run on Windows XP Pro computers. It will be run at log in and log out. The command to run this program will be set via GPO and will include command line operators to control what data the program sends. I have used a few built in C# classes to find out information about the computer, which is then sent of to a server as a web request. I need to know which of the following will have issues on a restricted user account on a domain. Enviroment ManagementObjectSearcher ManagmentObjectCollection System.Diagnostics.PerformanceCounter <-- side note, this class dosent seem to accept be saying using System.Diagnostics ComputerInfo WebRequest

  • Is there a way to expose multiple WCF services through a single endpoint?

    - by mafutrct
    I currently offer a service with many methods via WCF. I'd like to refactor so the single service is split into multiple classes, each offering a different set of functionality. However, I'd prefer to still have a single connection to the client. Is this possible? I guess the answer is No, so how should I solve this issue? Is there a workaround? Or is my idea completely stupid and I should change the design of the application?

  • What's the syntax to import a class in a default package in Java?

    - by Lord Torgamus
    Possible Duplicate: How to access java-classes in the default-package? Is it possible to import a class in Java which is in the default package? If so, what is the syntax? For example, if you have package foo.bar; public class SomeClass { // ... in one file, you can write package baz.fonz; import foo.bar.SomeClass; public class AnotherClass { SomeClass sc = new SomeClass(); // ... in another file. But what if SomeClass.java does not contain a package declaration? How would you refer to SomeClass in AnotherClass?

  • Need help on how to setup package structure and project

    - by jax
    I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

  • How do I replace "this" in Java with something that works.

    - by Luke Alderton
    I'm looking to get the showGUI() method work, the compiler says "this" is not a static variable and cannot be referenced from a static context, what would I use to replace "this"? I've tried test.main (test being the package it's in). The reason I'm using the static method showGUI() is because I need the method to be called from another static method, as well as the startup() method. Below are my two main classes. public class Main extends SingleFrameApplication { @Override protected void startup() { showGUI(); } @Override protected void configureWindow(java.awt.Window root) { } public static Main getApplication() { return Application.getInstance(Main.class); } public static void main(String[] args) { launch(Main.class, args); } public static void showGUI() { show(new GUI(this)); } } public class GUI extends FrameView { public GUI(SingleFrameApplication app) { super(app); initComponents(); } private void initComponents() { //all the GUI stuff is somehow defined here } }

  • How can I fix Grails error: "No domain class found for name PrivacyOptions. Please try again and e

    - by ?????
    I'm just getting started with Groovy/Grails. I added a new domain controller to my project, and generate-controller doesn't like it. There are other indications something's wrong: If I run the app no table is actually created in the database for this. I've reduced the DomainController to one String field and no constraints, just to make sure there wasn't something wrong with my specification. I also tried renaming it, just in case there was something about the original name (Privacy) that conflicted with something. I'm sure I have the correct name, and that the file is called PrivacyOptions.groovy and inside the class is also called PrivacyOptions. Here's the error: Running script /opt/local/grails/scripts/GenerateController.groovy Environment set to development Domain class not found in grails-app/domain, trying hibernate mapped classes... No domain class found for name PrivacyOptions. Please try again and enter a valid domain class name

  • how to set and access variable values from another classess

    I am modifying QuartzDemo example app and want to do set and read values of integer type variables in other classes which are already included. For example, in MainViewController.m I want to set a numeric value (simple numbers from 1-100) to a variable which is then going to be called (read) in file QuartzImages.m. Question is how to define variable properly, set and access (read) the value. I am a beginner with Obj C and iPhone SDK in general and have some experience with Delphi and VB but this doesn't help at all :) Thank you, whoever and wherever you are, person who will take me out of this endless googling loop.

  • How to use jquery .animate() to mock 'text-align:right'

    - by mrwienerdog
    I am building a very simple jquery menu. On hover, I have a menu on the right easing to the left margin of my menu container. This is easy, as the text is left aligned within said container. However, I also have a menu on the left, and because the links (left justified) are of differing length, the best I can do is adjust the padding to ease the text a uniform amount between links. Therefor, long link text goes to the right edge of the container, buy short text only makes it about half way. In reading about this, I have learned that you can not modify the text align property as it is non numeric. Is there any other way to do this? I of course tried to go with: $('#selector').css('text-align':'right') but that made the text jump to the right instead of ease. Is there any way to ensure all links ease to the rightmost margin of the container?

  • How to parse the multipart data in a restful service...

    - by AXS
    I have written a restful web service in c# and .net using the Restful Starter Kit that receives a mime multipart form via a stream. The multipart form contains a small xml fragment and a small file binary. I have read the stream in, and I have also written some code to parse the data to obtain the XML and the file binary. However, I feel that there should be some methods already written in the .net classes to allow me to access the two parts of the multipart form without having to parse the data myself. Does anyone have any ideas on how to do this?

  • In C#: How to declare a generic Dictionary whose key and value types have a common constraint type?

    - by Marcel
    Hi all, I want to declare a dictionary that stores typed IEnumerable's of a specific type, with that exact type as key, like so: private IDictionary<T, IEnumerable<T>> _dataOfType where T: BaseClass; //does not compile! The concrete classes I want to store, all derive from BaseClass, therefore the idea to use it as constraint. The compiler complains that it expects a semicolon after the member name. If it would work, I would expect this would make the later retrieval from the dictionary simple like: IEnumerable<ConcreteData> concreteData; _sitesOfType.TryGetValue(typeof(ConcreteType), out concreteData); How to define such a dictionary?
