3,636,880 | 3,636,881 | What is the difference in the way static methods and instance methods are used in Java. | <p>While reading a book, i came across this statement: </p>
<hr>
<p><em>The methods of an object define its behaviour. These methods are called instance methods. It is important to note that these methods pertain to each object of the class. <strong>This should not be confused with the implementation of the methods which is shared by all instances of the class.</em></strong></p>
<hr>
<p>I know what instance methods are, I know what static methods are (i.e. shared by all instances of the class). The above statement seem to suggest that the implementation of the methods is shared by all instances. What exactly does this mean? It doesnt sound like it is refering to static methods. </p>

<p><strong>Problem:</strong></p>
<p>creating the right paramter to use with <code>myCommmand(uint8 *pAddr)</code>, which will execute <code>send(pAddr, 6)</code>, which will use those parameters to loop the following 6 times:</p>
<p><code>write(reinterpret_cast<unsigned char*>(pAddr)[i]);</code></p>
<p>my trouble is, that pAddr has to point to an array of 6 bytes, which i most preferably would like to define as unsigned byte values (0-255) or as hex 00-FF.</p>
<p><strong>Restrictions</strong></p>
<p>Functions shall not be changed. It is just about creating the parameters.</p>
<p><strong>My attemps:</strong></p>
<pre><code>uint8 Addr[] = {00,22,122,205,16,04};
uint8 *pAddr = &Addr;
</code></pre>
<p>but this results in error C2440 (can't convert uint(*)[6] to uint8 *).</p>
<p><strong>Desired solution</strong></p>
<p>I would lik to know a <em>good</em>, wellformed way to create thise Addr-array or stream, or object to pass on to my functions, by writing their byte or hex values into my code - like in my attempt. I can use <em>boost</em>-libraries. Thanks to all helping me out with this!</p>

As I understand it, the main reasons against it are:</p>
<ul>
<li>It doesn't work very well/at all in IE </li>
<li>It is possible to run into conflict, such as if a framework uses <code>Document.prototype.hide</code> and a browser then implements a <code>hide</code> function on document elements</li>
<li>Browsers implement things in wildly different ways</li>
</ul>
<p>However, I haven't seen anyone ask these questions. </p>
<ol>
<li>If I wanted to extend the DOM, how would I do it safely? Besides the
obvious use of a wrapper, how would I natively add a function, such
as <code>hide</code> to the DOM as a whole, safely? </li>
<li>If it's not possible to implement it safely, what are the specific
reasons? Can I implement checks, such as checking <code>typeof
Document.prototype.hide == 'undefined'</code> before implementing my own
function on the prototype?</li>
</ol>
<p>In other words, explain to me how I can extend the DOM safely and what I could do to make sure that if a browser were to make the <code>hide</code> function, what I could do to not make my code have to be completely reworked. </p>

2,590,515 | 2,590,516 | What is the purpose of Session Data? | <p>I have searched many questions regarding <code>session_destroy</code> and the often response from the answerers involve quoting directly from the <a href="http://us.php.net/session_destroy" rel="nofollow">PHP manual</a> which states the following:</p>
<blockquote>
<p>session_destroy() destroys all of the data associated with the current
session. It does not unset any of the global variables associated with
the session, or unset the session cookie. To use the session variables
again, session_start() has to be called.</p>
<p>In order to kill the session altogether, like to log the user out, the
session id must also be unset. If a cookie is used to propagate the
session id (default behavior), then the session cookie must be
deleted. setcookie() may be used for that.</p>
</blockquote>
<p>In a question asking "<a href="http://stackoverflow.com/questions/4303311/what-is-the-difference-between-session-unset-and-session-destroy-in-php">What is the difference between session_unset() and session_destroy() in PHP?</a>", the answerer mentions about <code>$_SESSION</code> variable and session storage but never go deep enough.</p>
<p>I think a lot of confusion arising from the function <code>session_destroy</code> is due to the lack of understanding regarding session data and mixing it up with <code>$_SESSION</code> variable. I would like to know what is the actual purpose of session data if <code>$_SESSION</code> variable already contains that data?</p>
<p>Thanks.</p>

What is the best way to reference to this method? Everytime I call a function called <code>get</code> it should call <code>core::get()</code> and pass the same parameters.</p>
<p>All I could come up with was this:</p>

<p>On this page, click a block and see the black box that appears. The black box will appear on either the left or the right of the numbered blocks, depending on which side of the block has more room. You can resize your browser window and the blocks will re-arrange so there's only enough blocks on each line that will fit in the screen. So even when you re-size your browser window, the black box will still look to see which side of the block(that you clicked) has more room, and it will appear on that side.</p>
<p>I'm assuming this is done with jQuery, could someone describe the technique she used to do this? I couldn't really find and understand it from looking at her code. I would like to learn the technique to do this, so a description of how to do this would be fine, an example even better. Thanks! </p>

Its there a way to just cancel the AsyncTask if the user exit an activity? Because then the second time the user enter the same activity he wouldn't have to wait until previous finishes.

<p>When i run this it recurses through a remote share on the LAN and just simply displays the names of the folders found. This share primarily contains folders.</p>
