<p>I had to make it because Eclipse doesn't recognize the method startActivity in the webviewclient class. tostizza is just showing a Toast because I can't do that either in the webviewclient class.

<p>Additionally, I have the following piece of code</p>
<pre><code>def reflect(p,dir):
if(dir == 'X'):
func = lambda (a,b) : (a * -1, b)
else:
func = lambda (a,b) : (a, b * -1)
p = map(func,p)
print 'got', p

<p><code>points</code> is an array of tuples such as: <code>[(1, 1), (-1, 1), (-1, -1), (1, -1)]</code></p>
<p>If I call the above function in such a manner:</p>
<pre><code>print points
reflect(points,'X')
print points
</code></pre>
<p>the list <code>points</code> does not change. Inside the function though, the print function properly prints what I want.</p>
<p>Could someone maybe point me in some direction where I could learn how all this passing by value / reference etc works in python, and how I could fix the above ? Or maybe I'm trying too hard to emulate Haskell in python...</p>
<p>Thanks</p>

<p>Say instead of <code>p = map(func,p)</code> I do </p>
<pre><code>for i in range(len(p)):
p[i] = func(p[i])

<p>The value of the list is updated outside of the function, as if working by reference. Ugh, hope this is clear :S</p>

Then after the doc is generated, ideally, I would like to give the user the option to either view the document or download it. If they choose to download, I'd like to display the Save As file dialog box with an appropriate default file name. If they choose to view, I'd like to view the document in a new window regardless of the users local settings for a PDF extension (I'm not sure if a user can control whether a pdf is opened in a new window or now like they can for MS Office file extensions.)</p>
<p>The following code generates the doc and presents the user with a dialog box to save, but the default dialog is the name of the web page(e.g. WebPageName.pdf) rather than a default file name that I would prefer.</p>
<p>Is there a way to control what the default file name that is used to prefilled the Save As Dialog box?</p>
<p>I'm not sure how to get all this functionality in one link.</p>

<p>The child page uses these values to run a report. When I switch to a new report, all is well. If I change the values in the master page the master page and the sub page load events fire. </p>
<p>The load event for the sub page fires first, picks up the values from the master page which are still the old values and then finally the master page events fire and all the new values are stored. The report hasn't changed as it still ran from the old values.</p>

3,235,906 | 3,235,907 | jquery get attribute value when property is not set | <p>I simply want to get the current value of a field's attribute.</p>
<p>This field has a default value like:</p>

<p>When i want to get the validation attribute, i don't know if it has been updated before or if this is still the default value.</p>
<p>So the property get with <code>prop()</code> return <code>undefined</code> when the property is not set (not yet updated), and the <code>attr()</code> method return always the default value (that's not true actually for maintainability but that will be in the future).</p>
<p>Is there a method that check:</p>

495,128 | 495,129 | Synchronizing on synchronized collections-> performance issue | <p>Based on the answers below :
It is Still not clear to me: What does the synchronized construct on the concurrentMap do, if anything. i.e. in the case of a concurrentmap, what is the difference if any between synchronized(map) versus non synchronizing. <b><i>I am not interested in the correctness or believed goodness of the solution</i></b>. Just an answer to the question:
Q:What is the difference between synchronizing on a concurrentmap and not synchronizing on the same? Specifically with regard to performance.. will suffice. Nothing more please.<br>
I am only interested in what happens and no supplementary advice.</p>
<p>I have a theoretical question which I am having a bit of a mental problem resolving:
Assume I have a Concurrent Collection class say=>ConcurrentHashMap map;</p>
<p>Assume I have three methods:</p>
<pre><code>method1: synchronized(map){
doSomethingWithThemap(); //Assume put integers 1.. 1000000
}
method2:doSomethingWithThemap(); //Note it is not synchronized
method3:doSomethingElseWithThemap(); //Assume put integers 2000000.. 3000000
</code></pre>
<p>Now assume 2 TestCases:</p>
<hr>
<ul>
<li>TestCase1: Spawn two threads A & B. A calls method1 and B calls method3.</li>
<li>TestCase2: Spawn two threads A' & B'. A' calls method2 and B' calls method3.</li>
</ul>
<p>From a performance point of view I would expect TestCase2 to win, since from what I understand, in TestCase1 B cannot add to the map, albeit concurrent, since the synchronized block will hold the lock on the map, and this is not the case in TestCase2.</p>
<p>My Unit Tests DO NOT validate this hypothesis.</p>
<p>Q: What am I missing here. i.e. Given a synchronized block on a concurrentcollection is performance impacted at all? </p>

4,423,335 | 4,423,336 | AlarmManager launching multiple times | <p>I am using this code to create an Alarm in a activity that can be launched by the user.</p>

4,698,560 | 4,698,561 | is it possible to implement Java arrays without ever using the special array token [ ] | <p>This is a Java style question. The brackets empty declare an array reference. With the 'new' keyword, they instantiate. Without the 'new' keyword, they index. </p>
<pre><code>char[] myArray = new char[100];
output.format("%c\n", myArray[43]);

<p>Of these uses of the brackets, the first case is an anomaly since it uses a special token to declare and does not look like a normal Java reserved word or Java identifier and has no number between the brackets. Is there an alternative that avoids this anomalous case?</p>
<p>Edit: Why might this matter? Arrays might be faster or use less memory than collections classes.</p>

3,423,486 | 3,423,487 | Issue with generic types of ArrayList and interface inheritence | <p>I'm having trouble understanding why the following doesn't work and I'm sure the answer is related to something basic I am not understanding and I'm driving myself nuts and hope someone can help.</p>
<p>I understand about using interfaces in an ArrayList such that if I have:</p>
<pre><code>public interface Weapon { ... }
public class Gun implements Weapon { ...}
public class Knife implements Weapon { ... }
</code></pre>
<p>you can then insert anything that implements Weapon into the an array of weapons:</p>
<pre><code>ArrayList<Weapon> collection = new ArrayList<Weapon>;
collection.add(new Gun());
collection.add(new Knife();
</code></pre>
<p>and that's fantastic. I get that, but what is confusing me is the understanding of why <code>ArrayList<Gun></code> isn't compatible with <code>ArrayList<Weapon></code> in other ways. To illustrate,
the following is legal:</p>
<pre><code>public void interfaceIsTheArgument(Weapon w) { ... }
...
interfaceIsTheArgument(new Gun());
interfaceIsTheArgument(new Knife());
</code></pre>
<p>but the following is not:</p>
<pre><code>public void interfaceIsTheArgument(ArrayList<Weapon> w) { ... }
...
interfaceIsTheArgument(new ArrayList<Gun>());
interfaceIsTheArgument(new ArrayList<Knife>());
</code></pre>
<p>because the last function call reports that the method isn't applicable for its arguments. </p>
<p>My question is why if the method knows it tasks an ArrayList with an interface as the generic type, why isn't it okay to pass in an array list of knifes in that last statement?</p>
