Is there a way to access the super object when extending objects using $.extend?
I would like to extend an object, override a method, but call the overridden superclass method in the subclass method.
In my adventures studying the boost libraries, I've come across function signatures that have parameters which are a reference to a reference to an object.
Example:
void function(int && i);
What is the purpose/benefit of doing it this way rather than simply taking a reference to an object? I assume there is one if it's in boost.
I need some help defining the following object hierarchy/ database relationship in Hibernate
From the object sense – Agent is inherited from Person and Agency is inherited from Organization. they are inherited from Party which can have multiple Addresses associated with it
The database consists of
Agent
- ID
- Name
-PartyID (references Party.ID)
Agency
-ID
-Name
-PartyID (references Party.ID)
Address
-AddrID
-PartyID (references Party.ID)
-Street
Party.
-PartyID
I know this is kind of a dumb question, but does anyone have an elegant (or non-elegant) LINQ approach to transform a 2D array (object[,]) into a 1D array (object[]) comprised of the first dimension of the 2D array?
Hi All,
I want to know if I can find/reach UI components of running application under Android OS.
it is possible to catch the Button/DDL/.. that was clicked by the user in real-time,
example from other subject(web):
In browser I can listen to the events and catch the DOM object that was clicked,
in this way I can save the DOM object data.
catching UI components that was changed by the user will give the option to save UI componentdata, and to perform the user actions automatic.
Thanks.
This is something I encounter frequently, but I don't know the elegant way of doing. I have a collection of Foo objects. Foo has a method bar() that may return null or a Bar object. I want to scan the collection, calling each object's bar() method and stop on the first one returning an actual reference and return that reference from the scan.
Obviously:
foos.find(_.bar != null).bar
does the trick, but calls #bar twice.
hello,
I made a web application that I connect to it from a mobile device
and I used Ajax Request Object but the status of the object returned data is 500
and after search I found that this means Internel Server Error 500
Is there any suggestions what may be the reason ??
thanks
What classes do you use to make string placeholders work?
String template = "You have %1 tickets for %d",
Brr object = new Brr(template, {new Integer(1), new Date()});
object.print();
Hello everyone,
I have a 3D object with about 2000 or 3000 triangles. I want to reduce the number of triangle without affecting shape of object.
for eg, I have two triangles,
(1,1.5,2) (1.5,1.5,2) (1.7,2,2)
(1.5,1.5,2) (1.7,2,2) (2,1.5,2)
In this case these two triangle is same as a single triangle -
(1,1.5,2) (2,1.5,2) (1.7,2,2)
I dont want the manual method, But if there is any direct function or such thing which will reduce my triangle list.
Thank You.
Hi,
I'm using jQuery's selectors, especially id selector:
$("#elementId")...
How should I determine whether jQuery has found the element or not?
Even If the element with the specified id doesn't exist the next statement give me: [object Object]
alert($("#idThatDoesnotexist"));
So a collection in VB6 keeps track of a key for each object, and you can look up the object by its key.
Does that mean collections are implemented as some sort of hashtable under the hood? I realize you can have multiple items with the same key in a collection, hence the SOME SORT.
Anybody know what type data structure a VB6 collection is supposed to represent?
.NET contains its own equality comparison functionality, however I don't really understand how it works.
If the desired Equals() and == behaviour is to verify that every field of an object is equal to every field of another object, is it necessary to override Equals() with a method that does this explicitly?
Hi,
In the constructor of an object i need to create a WPF mediaElement object:
m_videoMedia = new MediaElement();
but the class can also be instantiated from a other thread so i need to use
Dispatcher.Invoke(DispatcherPriority.Normal,
(Action)(() => { m_videoMedia = new MediaElement(); }));
But how can I get the right dispatcher instance in that constructor :s
I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?
From the docs:
You usually access to-many
relationships using
mutableSetValueForKey:, which returns
a proxy object that both mutates the
relationship and sends appropriate
key-value observing notifications for
you.
So this returns an "intelligent" NSMutableSet which automatically lets the context delete objects when they get deleted from the set, and reverse? Is that a proxy object?
For instance:
private final Object o;
public void doSomething(){
final Object local = this.o;
//access methods of local;
}
This practice is followed in lots of java classes (such as ArrayBlockingQueue). What's the benefit of this?
hi all,
I found this structure called OBJECT_ATTRIBUTE in one of the nt dll functions..I was curious to know about that structure and I went through its documentation(msdn)...In the OBJECT_ATTRIBUTE structure there is a parameter called PUNICODE_STRING objectName...As per the msdn documentation..it says that the objectName "the name of the object for which a handle is to be opened" which is actually a name or some root directory,am confused with this.Can anybody explain this term "name of the object"(root directory).what it represents.
I'm trying to access the number in the below element, but I'm having trouble getting the value out of it.
echo $object->0; //returns Parse error: syntax error, unexpected T_LNUMBER, expecting T_STRING or T_VARIABLE or '{' or '$'
SimpleXMLElement Object (
[0:public] => 15810
)
Any ideas on how I can get that value?
Hi!
I would like implement spring acl for my object fields.
does anyone has an idea what do i have to implment for it?
for example, i have Purchase object.
i would like admin_role to have read on all the fields, and secretary_role to have read only on username and address field
Consider this piece of code:
public abstract class Validator
{
protected Validator()
{
}
protected abstract void ValidateCore(object instance, string value, IList<ValidationResult> results);
public void Validate(object instance, string value, IList<ValidationResult> results)
{
if (null == instance) throw new ArgumentNullException("instance");
if (null == results) throw new ArgumentNullException("results");
ValidateCore(instance, value, results);
}
}
Look at the Validate() overload, how can an abstract class have definitions like this?
i am displaying a object detail through display tag.

or any other way so that i can delete or edit perticular record

Is it possible to select certain data in a JSON Object using other data in the same JSON Object. Similar to MySQL. For example:
myObj = {"elements" : [ { "name" : "Hydrogen", "symbol" : "H" }, { "name" : "Silver", "symbol" : "Ag" }]};
I want to select "Hydrogen" where the symbol is "H". Instead of having to put in something like this:
document.getElementByID("TEST").innerHTML = myObj.elements[0].name;
Thank you in advance.
Hi,
I have a J2ME application - which generates XML data (from an object) and needs to get it sent across to a remote server/machine. How do I get this xml or the object through to the remote server please? Thanks. Just in case it might help, the receiving application on the remote server is PHP powered. Thanks again.
Hi all
I wanted to ask if there is a formal way of describing the following code, whereby we can access the same object repeatedly without re-typing the object's identifier:
myObj.render(1).render(2).print();
I didn't know how to describe it when trying to form a question; I wanted to know whether or not something like this is possible in javascript, I know that I can do it in VB:
myObj.render(1)
if(foo == 'bar')
.render(2)
.print();
Thanks!
I have a class that inherits from a generic dictionary as follows:
Class myClass : System.Collections.Generic.Dictionary<int, Object>
I have added a list of values to this in a particular order, but I now wish to change that order. Is there any way (without removing and re-adding) that I could effectively re-index the values; so change the object at index 1 to now be at index 10 for example? For example, this doesn't work:
myClass[1].Index = 10;
