• Android @Override usage

  - by BahaiResearch.com

  (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 "Virutal"? What then does @Override do? Example: private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } }

• PHP Speed - Many Echos vs Building a String

  - by Chris

  Wondering if anyone knows if either of these methods would produce an output faster: Method 1 for ($i=1;$i<99999;$i++) { echo $i, '<br>'; } or Method 2 for ($i=1;$i<99999;$i++) { $string .= $i . '<br>'; } echo $string; Thanks for any input you have.

• Passing Request Object into Service Layer

  - by SpringTrickery

  In a spring mvc + spring core app, we have have a view layers, a facade, a service layer, a dao layer and a stored-proc based persistance layer. The service layer is unaware of the clients that utilitize its methods. Is it fine to propagate raw http requests into the service layer? Or is it bad practice and a violation of the loose coupling principles? If it is, then what's a clean workaround?

• Auto comment all public members in a file

  - by ooo

  I have turned on warnings as errors and now i need to XML comment all of my public methods. just to get my program compiling, i just want to put placeholders for now. Is there anyway to automatically add XML comments to all of the public members in a class or a file. I see ghost doc which gives you good autogenerated XML comments but it still looks like it only does one member at a time.

• Accessing weakly typed facebook sdk result object properties in .NET 3.5 using the API?

  - by John K

  Consider the following in .NET 3.5 (using the Bin\Net35\Facebook*.dll assemblies): var app = new FacebookApp(); var result = app.Get("me"); // want to access result properties with no dynamic ... in the absence of the C# 4.0 dynamic keyword this provides only a generic object. How best should I access the properties of this result value? Are there helper or utility methods or stronger types in the facebook C# sdk, or should I use standard .NET reflection techniques?

• How should I lay-out my PHP login class?

  - by ThinkingInBits

  So, there is going to be one login form; however 1 of 3 types of members will be signing in member_type_a, member_type_b, member_type_c all of whom have some of the same properties, and some whom may have specific methods and/or properties to them. I want the class to be saved to a session variable for use with member area pages. Any suggestions on applicable design patterns?

• Detect if a method was overridden using Reflection (C#)

  - by Andrey

  Say I have a base class TestBase where I define a vistual method TestMe() class TestBase { public virtual bool TestMe() { } } Now I inherit this class: class Test1 : TestBase { public override bool TestMe() {} } Now, using Reflection, I need to find if the method TestMe has been overriden in child class - is it possible? What I need it for - I am writing a designer visualizer for type "object" to show the whole hierarchy of inheritance and also show which virtual methods were overridden at which level.

• a design to avoid circular reference in this scenario

  - by BDotA

  Here is our dependency tree: BigApp - Child Apps - Libraries ALL of our components are HEAVILY using one of the Libraries as above ( LibA). But it has a ‘few’ public methods that require classes from ‘higher-level’ assemblies and we want to avoid CIRCULAR references. What do you propose as a good design for this?

• Undefined function in php

  - by Bidyut

  I wrote three methods in a class and one is calling another, but when I call the function outside through the object, it is showing an undefined function error for the second function. Here's my code: function resize_image(){ } function image_resize(){ $a = resize_image(); } When I run this, it shows resize_image() as undefined. Here's the error: Fatal error: Call to undefined function resize_image() in /home/vacayge/public_html/Major/Alpha1/classes/cUserImages.php on line 2090

  I need to produce demonstration video screencasts for my iPhone app... I'm referring to those such as this one for the Reddit iPhone app (the one on the right, not the YouTube video). I'm assuming the best way to do this is to record the simulator using a screen recording utility, does anyone have any other methods? What tools have you used successfully?

  Using VS2010, I can't seem to add additional test methods. If I set up my project like this [TestMethod] public void Test1() { Assert.AreNotEqual(0,1); } [TestMethod] public void Test2() { Assert.AreNotEqual(0,1); } The only test that shows up in my Test View is Test1. How do I make sure Test2 gets in to that list?

• group member dropdown in visual studio 2008

  - by knittl

  in visual studio is the member dropdown, where you can select all members of the current type alphabetically ordered. is there an option which allows grouping of the members? i.e. all constructors before all methods before all properties before all events before all fields? if there is not, bad for me, i guess—it would really enhance productivity

• Problem with RSA-encrypting a string in PHP and passing it to .NET service

  - by jonasaxelsson

  I need to call a web service that requires a login url containing an RSA encrypted, base_64 encoded and url-encoded login data. I don't have a formal php training, but even for me it seems like an easy task, however when calling the service I get an 'Invalid Format' response. What am I doing wrong and is there another way to come up with the encrypted string? Code example below. Thank you for your help! http://www.edsko.net/misc/ for encryption. $message = '?id=112233&param1=hello&[email protected]&name=Name'; $keyLength = '2048'; $exponent = '65537'; $modulus = '837366556729991345239927764652........'; $encryptedData = rsa_encrypt($message, $exponent, $modulus, $keyLength); $data = urlencode(base64_encode($encryptedData)); $loginurl = 'http://www.somedomain.com/LoginWB.aspx?Id=9876&Data='.$data; echo '<iframe src="'.$loginurl.'" width="570px" height="800px">'; echo '</iframe>'; ?

• How to add a method to an existing class in PHP?

  - by sombe

  I'm using WordPress as a CMS, and I want to extend one of its classes without having to inherit from another class; i.e. I simply want to "add" more methods to that class: class A { function do_a() { echo 'a'; } } then: function insert_this_function_into_class_A() { echo 'b'; } (some way of inserting the latter into A class) and: A::insert_this_function_into_class_A(); # b Is this even possible in tenacious PHP?

• How can I map a String to a function in Java?

  - by Bears will eat you

  Currently, I have a bunch of Java classes that implement a Processor interface, meaning they all have a processRequest(String key) method. The idea is that each class has a few (say, <10) member Strings, and each of those maps to a method in that class via the processRequest method, like so: class FooProcessor implements Processor { String key1 = "abc"; String key2 = "def"; String key3 = "ghi"; // and so on... String processRequest(String key) { String toReturn = null; if (key1.equals(key)) toReturn = method1(); else if (key2.equals(key)) toReturn = method2(); else if (key3.equals(key)) toReturn = method3(); // and so on... return toReturn; } String method1() { // do stuff } String method2() { // do other stuff } String method3() { // do other other stuff } // and so on... } You get the idea. This was working fine for me, but now I need a runtime-accessible mapping from key to function; not every function actually returns a String (some return void) and I need to dynamically access the return type (using reflection) of each function in each class that there's a key for. I already have a manager that knows about all the keys, but not the mapping from key to function. My first instinct was to replace this mapping using if-else statements with a Map<String, Function>, like I could do in Javascript. But, Java doesn't support first-class functions so I'm out of luck there. I could probably dig up a third-party library that lets me work with first-class functions, but I haven't seen any yet, and I doubt that I need an entire new library. I also thought of putting these String keys into an array and using reflection to invoke the methods by name, but I see two downsides to this method: My keys would have to be named the same as the method - or be named in a particular, consistent way so that it's easy to map them to the method name. This seems WAY slower than the if-else statements I have right now. Efficiency is something of a concern because these methods will tend to get called pretty frequently, and I want to minimize unnecessary overhead. TL; DR: I'm looking for a clean, minimal-overhead way to map a String to some sort of a Function object that I can invoke and call (something like) getReturnType() on. I don't especially mind using a 3rd-party library if it really fits my needs. I also don't mind using reflection, though I would strongly prefer to avoid using reflection every single time I do a method lookup - maybe using some caching strategy that combines the Map with reflection. Thoughts on a good way to get what I want? Cheers!
