Is it possible? Normally, it requires two lines: $instance = new MyClass(); $variable = $instance->method(); Is something like this possible in PHP?: $variable = new MyClass()->method(); Of course, the first code is better for readability and clean code, etc., but I was just curious if you can shrink it. Maybe it could be useful, ...

Say you have two different classes where each have their own implementation of Equals; which one is used? What if only one of them have one? Or none of them? Are any of the following lines equivalent? object .Equals( first, second ) first .Equals( second ) second .Equals( first ) I'm guessing that the first two might be equivalent, bu...

Hey everyone, So I have been working on a 2 player Tic-Tac-Toe game in java that utilizes sockets. All of the socket stuff is working, and I am sending data back and forth successfully between 2 clients and a server. I have the following classes: Requester, Provider, and TBoard (which extends Serializable). In the Requester (client) c...
I think this is more of a polymorphism question but it applies to SubSonic table objects... Here's the thing (and I love this one): TblUser userObj = new TblUser(1); Which fills userObj's properties with all of PK=1's goodies. Now, I'd like to add more properties to the existing user object, for example, an ArrayList property of say,...

I have a list of objects that I would like to store in a file as small as possible for later retrieval. I have been carefully reading this tutorial, and am beginning (I think) to understand, but have several questions. Here is the snippet I am working with: static bool writeHistory(string fileName) { fstream historyFile; historyFi...
I have a table of data on my page. The columns are "start", "end", "comment", and "options". Within the options column is a button to delete the row, and a button that makes a row of the table editable. This allows the values of "start", "end", and "comment" to be changed. Clicking it again finishes the editing process. Finally, there is...

This is something that has been bugging me since I took up AS3 a year ago. Example. I make a class that extends a Movie Clip and call it "LoaderBar" all it is is some text that says "Loading" and below it another movie clip that is a plain rectangle that I call "lBar" When I call a function to load my image I add the Loader to the st...
This code only works when async is set to false, why? var contact = { XMLHttp : null, XMLDoc : null, TXTDoc : null, getData : function(dataSource) { contact.XMLHttp = new XMLHttpRequest(); contact.XMLHttp.open("GET", dataSource, false); contact.XMLHttp.onreadystatechange = contact.storeData; contact.XMLHttp.send(null); }...
Assuming both objects are not value types and both represent types which have overridden the Equals(...) method, is there any functional difference between: Calling obj1.Equals(obj2) Calling Object.Equals(obj1, obj2) ...or are they functionally the same? The Apress book I'm reading (Pro C# 2008), which is actually quite good, refers ...
We all get "TypeError #1009 Cannot access a property or method of a null object reference" now and then - no big deal, but sometimes frustrating to debug. Flash gives you the call stack (which is a start), but leaves it up to you to figure out where the null object is - is it possible to find out exactly which reference is throwing the...
Please see the following script: var x = function(param){ this.data=param; this.y = function(){ alert(this.data) } return this; } /* x.prototype.z = function(){ alert(this.data); } */ x(123).y(); x(123).z(); // This should behave same as y() When I call x(123).y() then message displays 123. ...

To me Object role modeling makes a lot more sense. Could you make a brief but easy to understand comparison if they can be compared. Cheers ...

I have an object which itself has multiple objects as fields. The question I have is, I have two objects of these kind and I want to compare these two. I know I can do equals, comparator etc. but is there a way to use reflection to get the properties of the object and make comparison. for example, if I have a Car object, which as wheel...
