<h2>37.1.1. IC Objects<a class="headerlink" href="#ic-objects" title="Permalink to this headline">¶</a></h2>
<p><a class="reference internal" href="#ic.IC" title="ic.IC"><code class="xref py py-class docutils literal notranslate"><span class="pre">IC</span></code></a> objects have a mapping interface, hence to obtain the mail address
you simply get <code class="docutils literal notranslate"><span class="pre">ic['MailAddress']</span></code>. Assignment also works, and changes the
option in the configuration file.</p>
<p>The module knows about various datatypes, and converts the internal IC
representation to a “logical” Python data structure. Running the <a class="reference internal" href="#module-ic" title="ic: Access to the Mac OS X Internet Config. (deprecated) (Mac)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">ic</span></code></a>
module standalone will run a test program that lists all keys and values in your
IC database, this will have to serve as documentation.</p>
<p>If the module does not know how to represent the data it returns an instance of
the <code class="docutils literal notranslate"><span class="pre">ICOpaqueData</span></code> type, with the raw data in its <code class="xref py py-attr docutils literal notranslate"><span class="pre">data</span></code> attribute.
Objects of this type are also acceptable values for assignment.</p>
<p>Besides the dictionary interface, <a class="reference internal" href="#ic.IC" title="ic.IC"><code class="xref py py-class docutils literal notranslate"><span class="pre">IC</span></code></a> objects have the following
methods:</p>

<dd><p>Parse the given URL, launch the correct application and pass it the URL. The
optional <em>hint</em> can be a scheme name such as <code class="docutils literal notranslate"><span class="pre">'mailto:'</span></code>, in which case
incomplete URLs are completed with this scheme. If <em>hint</em> is not provided,
incomplete URLs are invalid.</p>
</dd></dl>
<dl class="method">

<dd><p>Find a URL somewhere in <em>data</em> and return start position, end position and the
URL. The optional <em>start</em> and <em>end</em> can be used to limit the search, so for
instance if a user clicks in a long text field you can pass the whole text field
and the click-position in <em>start</em> and this routine will return the whole URL in
which the user clicked. As above, <em>hint</em> is an optional scheme used to complete
incomplete URLs.</p>

filename or an <code class="xref py py-func docutils literal notranslate"><span class="pre">FSSpec()</span></code> result, and which need not exist.</p>

is the entry version number, <em>type</em> is the 4-character filetype, <em>creator</em> is
the 4-character creator type, <em>postcreator</em> is the 4-character creator code of
an optional application to post-process the file after downloading, <em>flags</em> are
various bits specifying whether to transfer in binary or ascii and such,
<em>extension</em> is the filename extension for this file type, <em>appname</em> is the
printable name of the application to which this file belongs, <em>postappname</em> is
the name of the postprocessing application, <em>mimetype</em> is the MIME type of this
