5,838,475 | 5,838,476 | Apply jQuery function to one element and *NOT* its descendants | <p>I want to add certain classes to the various levels of my websites nav header. So I'll have something in the end like</p>
<pre><code>$('#navCol > ul > li > ul > li > ul').addClass('lvl2');
// Each ‘li > ul’ past the first ‘ul’ indicates another sub-level.
</code></pre>
<p>to add the <code>lvl2</code> class to the second level, etc. Having said that, not only does it apply said class to the second level, it also adds it to the other <code>ul</code>s beneath it. Is there a way to specify that I only want to include the element and not its descendants.</p>

3,551,113 | 3,551,114 | Handling large strings in Android (OutOfMemeryError) | <p>I am currently working on an Android application and has encountered an OutOfMemoryError on a Motorola Defy. </p>
<p>The place where the error occurs, is where I convert a 5MP image to a Base64 encoded string which subsequently is sent to a web service contained in a SOAP document. </p>
<p>I am aware, that both the actual encoding of the image, and using SOAP both are overheads - and would prefer myself to eliminate those - but that is not possible right now. </p>
<p>My question goes more on how to handle the large strings, being not to much into Java and Memory handling I need a little assistance. </p>
<p>The code is approx like this: </p>
<pre><code>String soapMessage = registration.createSoapRequest();
//In this method a StringBuilder is used to build the message, and returns it
//as new String(soap.toString();
//At this point I have to objects in memory using approx 6 and 9 MB each.
//I would expect it to be the StringBuilder and the string soapMessage.
//But I can't figure out how to GC the StringBuilder - which I don't need to use
//any more.
//Declaring the entity to post
StringEntity entity = new StringEntity(soapMessage, HTTP.UTF_8);
//By declaring the entity, I receive my OutOfMemoryException, due to having
//the 6-7 MB string now replicated 3 times - giving 21 MB alone.
entity.setContentType("text/xml");
//Creating client
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://MYSERVER/services/registration.svc");
post.setHeader("Content-Type","text/xml; charset=utf-8");
post.setHeader("SOAPAction", "http://tempuri.org/IRegistration/PostRegistration");
post.setEntity(entity);
BasicHttpResponse response = (BasicHttpResponse)client.execute(post);
</code></pre>
<p>The obvious Memory issue here seems to make me able to only hold one instance of the string in memory. </p>
<p>How would I do this?</p>
<p>I hope somebody can help me through this as I feel stuck in Java Memory handling.</p>
<p>Best regards
/Anders</p>

<p>Many times I see the use of this kind of code and even I use the same. But, there are still few things unclear. </p>
<ol>
<li>The above is a call to <code>someFunction</code> as soon as the page loads, right. But, aren't we supposed to call a function with brackets <code>()</code>?</li>
<li>From my understanding, we are just assigning <code>someFunction</code> to <code>window.onload</code>, therefore can we or shouldn't we call <code>window.onload()</code>;</li>
<li>Are there such cases, when <code>functionName()</code> and <code>functionName</code> becames interchangeable. Because at many places, and in various API, I have seen calling the function without brackets.</li>

5,298,633 | 5,298,634 | A case where named constants are not needed over magic numbers | <p>Obviously the point of using named constants over magic numbers is for code clarity and for not having to go through code changing numbers throughout.</p>
<p>However, what do you do if you just have a number used just once in a function? Say you have a short member function that uses an object's velocity (which we'll say won't change) to calculate its motion, but this is the only function that uses that velocity. Would you...</p>
<p>A) Give the class a named static constant to use</p>
<p>B) Put a named constant in the function</p>
<p>C) Use the magic number but comment it</p>
<p>D) Other...</p>
<p>I am kind of leaning towards using a magic number and commenting it if the number is ONLY BEING USED ONCE, but I'd like to hear others' thoughts.</p>
<p>Edit: Does putting a named constant in a function called many times and assigning to it have performance implications? If it does I guess the best approach would be to put the constant in a namespace or make it a class variable, etc.</p>

<p>I'm first checking to see if the <code>eform</code> object has the property specified by the variable <code>funcName</code>. If it does, then I need to check whether that property has an <code>init</code> method.</p>
<p>Is there any way to combine these into a single <code>if</code> statement? Or perhaps something even more elegant than that?</p>

857,721 | 857,722 | Create a flattened representation of an class based on its MRO | <p>How would I create a flattened representation of a class that is composed of multiple base classes/mixins. Is there a library for doing such a thing? For example:</p>
<pre class="lang-py prettyprint-override"><code>class Foo(object):
def a(self):
return
class Bar(object):
def b(self):
return
class Baz(Foo, Bar):
pass
</code></pre>
<p>I want to be able to create a text representation of the flattened class that would look like this:</p>
<pre class="lang-py prettyprint-override"><code>class Baz(object):
def a(self):
return
def b(self):
return
</code></pre>
<p>The idea would be to create a text editor plugin (ST2 in my case) to allow the user to right-click on a class name and select an option to have a tab open with the flattened class displayed for reference.</p>
<p>Of course the tool would need to be smart enough to treat super calls as basically includes.</p>

<p>Initially i used <code>MyDialog.setCanceledOnTouchOutside(true);</code> But these will only dismiss and in my case, at the same time i want to call some functions whenever user click outside of dialog.

2,222,435 | 2,222,436 | Android Location Listener (or Android Events in general) | <p>I have a general question about LocationListener in Android. Perhaps this is about Android or Java events in general, but not sure. </p>
<p>There seems to be a million ways to set up a LocationListener, and they all seem pretty ugly (mainly because of lack of reusability). Here is an example from android found <a href="http://developer.android.com/guide/topics/location/obtaining-user-location.html" rel="nofollow">here</a>:</p>
<pre><code>// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
</code></pre>
<p>This works, but, I'm really surprised that this is a standard way of writing OOP code...</p>
<p>What I would really like to see is a simple a <em>reusable</em> way to implement LocationListener. Anybody know of a simple tutorial on how this could be done? My goal would be to be able to implement this easily any Activities that need to be updated with gps information... perhaps a Service? Thanks!</p>
