I have an app where I've pushed two items onto the navigation bar. The top item, which ends up as a 'back' button, should have the function to jump all the way back to the start page, which is a list of web news. The other one simply displays a logo. The boss wants a navigation bar look and feel but with a simple function, so the user ca...
@Embedded public class EmbedMe { private String prop1; private String prop2; } @Entity public class EncryptedEmbedded { @Embeddable private EmbedMe enc; } I am current using Jasypt for encryption. Is there a way to indicate that the @Embeddable in EncryptedEmbedded will use @Type(value = "newDeclaredTypeHere") per attr...
Can I somehow force a derived class to always call the overridden methods base? public class BaseClass { public virtual void Update() { if(condition) { throw new Exception("..."); // Prevent derived method to be called } } } And then in a derived class : public override void Update() { ...
I'm using the JQuery autocomplete plugin. I wish to override the implementation of the filllist() function. Can someone point me to an example of how to do this? ...
(Newbie to Java, old time C# guy.) I have noticed a lot of the use of @Override in Android example code. I thought that all Java methods were by default "Virtual"? What then does @Override do? Example: private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url)...
For example, using my UserProfile model: class UserProfile(models.Model): user = models.ForeignKey( User, unique=True ) blurb = models.CharField( max_length=200, null=True, blank=True ) public = models.BooleanField( default=True ) ... Thus, I end up with a field called "public". This doesn't jive in ActionScript be...
I'm having the following classes: class Base { public virtual void Print() { Console.WriteLine("Base"); } } class Der1 : Base { public new virtual void Print() { Console.WriteLine("Der1"); } } class Der2 : Der1 { public override void Print() { Console.WriteLine("Der2"); } } ...
Hay, i have a simple model class Manufacturer(models.Model): name = models.CharField() car_count = models.IntegerField() class Car(models.Model): maker = ForeignKey(Manufacturer) I want to update the car_count field when a car is added to a manufacturer, I'm aware i could just count the Manufacturer.car_set() to get the v...
What is the best way to override jre_lib classes? Let's say I need to store all ArrayLists not in RAM but on disk or anywhere else. I wanna write my own ArrayList class to code this functionality and make sure that every instantiations of ArrayList use my class. I thought about class loading mechanism to change order of classpath, but ...
C++ and Java support return-type covariance when overriding methods. Neither, however, support contra-variance in parameter types - instead, it translates to overloading (Java) or hiding (C++). Why is that? It seems to me that there is no harm in allowing that. I can find one reason for it in Java - since it has the "choose-the-most-sp...
I'm using a flex component that use a to load a .swf file. The loaded .swf - is passed to me as is and I can't edit - it has some as3 functions in it Is it possible in the "parent" application (the one with ) to override functions included in the "child" swf (the imported one)? And if it's possible, how? Thanks ...
How do I process a signal of in a subclass? Let's say my subclass is derived from QTextEdit and is interested in the signal textChanged. It seems silly to connect an object to itself, I should be able to simply override the textChange method -- but it isn't virtual. What is the accepted way to do this? ...
When overriding a method in Java is it possible to call the "original" one. For example: public class A extends B{ @Override public void foo(){ System.out.println("yep"); // Then execute foo() as it's defined in B } } ...
So I'm working on pypreprocessor which is a preprocessor that takes c-style directives and I've been able to make it work like a traditional preprocessor (it's self-consuming and executes postprocessed code on-the-fly) except that it breaks library imports. The problem is. The preprocessor runs through the file, processes' it, outputs t...
I would like to override bool's TryParse method to accept "yes" and "no." I know the method I want to use (below) but I don't know how to override bool's method. ... bool TryParse(string value, out bool result) { if (value == "yes") { result = true; return true; } else if (value == "no") { res...
Hi To resolve a jQuery slideDown/Up problem, I had to change one line in the jQuery file. I changed line 5738 from this.elem.style.display = "block"; to this.elem.style.display = "inline-block"; The block attribute messed up my lists when using slideDown/Up/Toggle. slideDown changes my list from display:inline to display:block during ...
I'd like to use the user updated values of a ManyToManyField in a model's overriden save() method when I save an instance in admin. It turns out that by design, django does not update the M2M field before calling save(), but only after the save() is complete as part of the form save... e.g. in both print commands bellow the values disp...
I was looking at this blog post and had following questions: Why do we need the new keyword, is it just to specify that a base class method is being hidden. I mean, why do we need it? If we don't use the override keyword, aren't we hiding the base class method? Why is the default in C# to hide and not override? Why have the designers i...
My current task is taking a Java project written and developed in Ubuntu NetBeans (extensively using the palette, which, it seems to me, locks me into continuing to use NB) and transferring it to XP, as it involves software that interfaces with a webcam and the client strictly uses XP. In Ubuntu, the project compiles correctly and compl...
