properties

问题 Is there a quick way to "super" deep clone a node, including its properties? (and methods, I guess) I've got something like this: var theSource = document.getElementById("someDiv") theSource.dictator = "stalin"; var theClone = theSource.cloneNode(true); alert(theClone.dictator); The new cloned object has no dictator property. Now, say I've got a thousand properties attached to theSource - how can I (non-explicitly) transfer/copy them to the clone? // EDIT @Fabrizio Your hasOwnProperty answer

问题 I am trying to load a properties file. The properites file is in the class path of the application. Properties p = new Properties(); p.load(new FileInputStream("classpath:mail.properties")); System.out.println(p.get("hi")); Now I say classpath, because another file called x.properties is referred in an xml file like this <property name="x"> <util:properties location="classpath:x.properties" /> </property> I placed my mail.properties in the same folder as x.properties, but my Java program is

问题 I want to duplicate a class. It is sufficient that I copy all properties of that class. Is it possible to: loop thru all properties of a class? assign each property to the other property, like a.prop := b.prop ? The getters and setters should take care of the underlying implementation details. EDIT: As Francois pointed out I did not word my question carefully enough. I hope the new wording of the question is better SOLUTION: Linas got the right solution. Find a small demo program below.

问题 Possible duplicate: Looping through properties in a class The problem is I have number of UILabels on each row upon a UITableView and I need to map the properties of my model class (which are of course NSStrings) to the label titles. As there are multiple labels(More than 12, and it might increase later in my project), hence I was using a for loop to allocate all the labels. But for mapping the variables to the labels I have to hard code each time for the corresponding label. Is there any way

问题 I want to create a login screen with localization option to translate the name and when i change from the default English to Arabic it crash here is the faces.config.xml <?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd" version="2.0"> <application> <locale-config> <default-locale>en<

问题 Is it possible to set a property of a class as a object? Like: class User { public $x = ""; public $y = new ErrorVO(); public $w = new array(); } 回答1: In the constructor, yes. class User { public $x = ""; public $y = null; public $w = array(); public function __construct() { $this->y = new ErrorVO(); } } Edit KingCrunch made a good point: You should not hard-code your dependencies. You should inject them to your objects (Inversion of Control (IoC)). class User { public $x = ""; public $y =

问题 guys. I'm studying up on properties for objects and one thing caught my eye on a source of info. There was this one part of the whole document that stated this about JS. Prototype Properties JavaScript objects inherit the properties of their prototype. The delete keyword does not delete inherited properties, but if you delete a prototype property, it will affect all objects inherited from the prototype. I'm kinda lost here... I know that sounds dumb but I need to understand exactly what that

问题 Yeah, I'm struggling with that. I cannot distinguish among them because every explanation I read is so unclear and philosophical enough. Can someone clear up these definitions for me ? Thanks guys. These definitions apply as much to procedural-programming as oop ? Thanks. 回答1: Function is a combination of instructions coupled together to achieve some result. It may take arguments and return result. If a function doesn't return a result it is usually called a procedure. Examples: function

问题 Because I didn't want to implement a communication protocol for my client-server based application, I implemented a RMI client and a RMI server on both sides for the information exchange between the two components. If I try to use my application by starting the two components on the same machine, everything is working fine. But if I split the components to two different computers (Kubuntu 9.04 within as a virtual machine within an Windows 7 RC environment with disabled firewall and a native
