<div class="descr">
<h2>Detailed Description</h2>
<p>The Q3UrlOperator class provides common operations on URLs.</p>
<p>This class operates on hierarchical structures (such as filesystems) using URLs. Its API facilitates all the common operations:</p>
<table class="generic">
<thead><tr class="qt-style"><th >Operation</th><th >Function</th></tr></thead>
<tr valign="top" class="odd"><td >List files</td><td ><a href="q3urloperator.html#listChildren">listChildren</a>()</td></tr>
<tr valign="top" class="even"><td >Make a directory</td><td ><a href="q3urloperator.html#mkdir">mkdir</a>()</td></tr>
<tr valign="top" class="odd"><td >Remove a file</td><td ><a href="q3urloperator.html#remove">remove</a>()</td></tr>
<tr valign="top" class="even"><td >Rename a file</td><td ><a href="q3urloperator.html#rename">rename</a>()</td></tr>
<tr valign="top" class="odd"><td >Get a file</td><td ><a href="q3urloperator.html#get">get</a>()</td></tr>
<tr valign="top" class="even"><td >Put a file</td><td ><a href="q3urloperator.html#put">put</a>()</td></tr>
<tr valign="top" class="odd"><td >Copy a file</td><td ><a href="q3urloperator.html#copy">copy</a>()</td></tr>
</table>
<p>You can obtain additional information about the URL with <a href="q3urloperator.html#isDir">isDir</a>() and <a href="q3urloperator.html#info">info</a>(). If a directory is to be traversed using <a href="q3urloperator.html#listChildren">listChildren</a>(), a name filter can be set with <a href="q3urloperator.html#setNameFilter">setNameFilter</a>().</p>
<p>A Q3UrlOperator can be used like this, for example to download a file (and assuming that the FTP protocol is registered):</p>
<pre class="cpp"> <span class="type">Q3UrlOperator</span> <span class="operator">*</span>op <span class="operator">=</span> <span class="keyword">new</span> <span class="type">Q3UrlOperator</span>();
op<span class="operator">-</span><span class="operator">></span><a href="q3urloperator.html#copy">copy</a>( <span class="type"><a href="qstring.html">QString</a></span>(<span class="string">"ftp://ftp.qt.nokia.com/qt/source/qt-2.1.0.tar.gz"</span>)<span class="operator">,</span>
<span class="string">"file:///tmp"</span> );</pre>
<p>If you want to be notified about success/failure, progress, etc., you can connect to Q3UrlOperator's signals, e.g. to <a href="q3urloperator.html#start">start</a>(), <a href="q3urloperator.html#newChildren">newChildren</a>(), <a href="q3urloperator.html#createdDirectory">createdDirectory</a>(), <a href="q3urloperator.html#removed">removed</a>(), <a href="q3urloperator.html#data">data</a>(), <a href="q3urloperator.html#dataTransferProgress">dataTransferProgress</a>(), <a href="q3urloperator.html#startedNextCopy">startedNextCopy</a>(), <a href="q3urloperator.html#connectionStateChanged">connectionStateChanged</a>(), <a href="q3urloperator.html#finished">finished</a>(), etc. A network operation can be stopped with <a href="q3urloperator.html#stop">stop</a>().</p>
<p>The class uses the functionality of registered network protocols to perform these operations. Depending of the protocol of the URL, it uses an appropriate network protocol class for the operations. Each of the operation functions of Q3UrlOperator creates a <a href="q3networkoperation.html">Q3NetworkOperation</a> object that describes the operation and puts it into the operation queue for the network protocol used. If no suitable protocol could be found (because no implementation of the necessary network protocol is registered), the URL operator emits errors. Not every protocol supports every operation, but error handling deals with this problem.</p>
<p>To register the available network protocols, use the qInitNetworkProtocols() function. The protocols currently supported are:</p>
<ul>
<li><a href="q3ftp.html">FTP</a>,</li>
<li><a href="q3http.html">HTTP</a>,</li>
<li><a href="q3localfs.html">local file system</a>.</li>
</ul>

<p>Copies the file <i>from</i> to <i>to</i>. If <i>move</i> is true, the file is moved (copied and removed). <i>from</i> must point to a file and <i>to</i> must point to a directory (into which <i>from</i> is copied) unless <i>toPath</i> is set to false. If <i>toPath</i> is set to false then the <i>to</i> variable is assumed to be the absolute file path (destination file path + file name). The copying is done using the <a href="q3urloperator.html#get">get</a>() and <a href="q3urloperator.html#put">put</a>() operations. If you want to be notified about the progress of the operation, connect to the <a href="q3urloperator.html#dataTransferProgress">dataTransferProgress</a>() signal. Bear in mind that the <a href="q3urloperator.html#get">get</a>() and <a href="q3urloperator.html#put">put</a>() operations emit this signal through the <a href="q3urloperator.html" class="compat">Q3UrlOperator</a>. The number of transferred bytes and the total bytes that you receive as arguments in this signal do not relate to the whole copy operation; they relate first to the <a href="q3urloperator.html#get">get</a>() and then to the <a href="q3urloperator.html#put">put</a>() operation. Always check what type of operation the signal comes from; this is given in the signal's last argument.</p>
<p>At the end, <a href="q3urloperator.html#finished">finished</a>() (with success or failure) is emitted, so check the state of the network operation object to see whether or not the operation was successful.</p>
<p>Because a move or copy operation consists of multiple operations (<a href="q3urloperator.html#get">get</a>(), <a href="q3urloperator.html#put">put</a>() and maybe <a href="q3urloperator.html#remove">remove</a>()), this function doesn't return a single <a href="q3networkoperation.html" class="compat">Q3NetworkOperation</a>, but rather a list of them.

<p>Tells the network protocol to get data from <i>location</i> or, if it is empty, to get data from the location to which this URL points (see <a href="q3url.html#fileName">Q3Url::fileName</a>() and <a href="q3url.html#encodedPathAndQuery">Q3Url::encodedPathAndQuery</a>()). What happens then depends on the network protocol. The <a href="q3urloperator.html#data">data</a>() signal is emitted when data comes in. Because it's unlikely that all data will come in at once, it is common for multiple <a href="q3urloperator.html#data">data</a>() signals to be emitted. The <a href="q3urloperator.html#dataTransferProgress">dataTransferProgress</a>() signal is emitted while processing the operation. At the end, <a href="q3urloperator.html#finished">finished</a>() (with success or failure) is emitted, so check the state of the network operation object to see whether or not the operation was successful.</p>
<p>If <i>location</i> is empty, the path of this <a href="q3urloperator.html" class="compat">Q3UrlOperator</a> should point to a file when you use this operation. If <i>location</i> is not empty, it can be a relative URL (a child of the path to which the <a href="q3urloperator.html" class="compat">Q3UrlOperator</a> points) or an absolute URL.</p>
<p>For example, to get a web page you might do something like this:</p>
<pre class="cpp"> <span class="type"><a href="q3urloperator.html">Q3UrlOperator</a></span> op( <span class="string">"http://www.whatever.org/cgi-bin/search.pl?cmd=Hello"</span> );
op<span class="operator">.</span>get();</pre>
<p>For most other operations, the path of the <a href="q3urloperator.html" class="compat">Q3UrlOperator</a> must point to a directory. If you want to download a file you could do the following:</p>
<pre class="cpp"> <span class="type"><a href="q3urloperator.html">Q3UrlOperator</a></span> op( <span class="string">"ftp://ftp.whatever.org/pub"</span> );
<span class="comment">// do some other stuff like op.listChildren() or op.mkdir( "new_dir" )</span>
op<span class="operator">.</span>get( <span class="string">"a_file.txt"</span> );</pre>
<p>This will get the data of ftp://ftp.whatever.org/pub/a_file.txt.</p>
<p><i>Never</i> do anything like this:</p>
<pre class="cpp"> <span class="type"><a href="q3urloperator.html">Q3UrlOperator</a></span> op( <span class="string">"http://www.whatever.org/cgi-bin"</span> );
op<span class="operator">.</span>get( <span class="string">"search.pl?cmd=Hello"</span> ); <span class="comment">// WRONG!</span></pre>
<p>If <i>location</i> is not empty and relative it must not contain any queries or references, just the name of a child. So if you need to specify a query or reference, do it as shown in the first example or specify the full URL (such as http://www.whatever.org/cgi-bin/search.pl?cmd=Hello) as <i>location</i>.</p>
