<h2>Detailed Description</h2>
<p>The QContactManagerEngineFactory class provides the interface for plugins that implement <a href="qcontactmanagerengine.html">QContactManagerEngine</a> functionality.</p>
<p>This class provides a simple interface for the creation of manager engine instances. Each factory has a specific id associated with it, which forms the <tt>managerName</tt> parameter when creating <a href="qcontactmanager.html">QContactManager</a> objects.</p>
<p>More information on writing a contacts engine plugin is available in the <a href="contactsengines.html">Qt Contacts Manager Engines</a> documentation.</p>

<p>This function is called by the <a href="qcontactmanager.html">QContactManager</a> implementation to create an instance of the engine provided by this factory.</p>
<p>The <i>parameters</i> supplied can be ignored or interpreted as desired.</p>
<p>If a supplied parameter results in an unfulfillable request, or some other error occurs, this function may return a null pointer, and the client developer will get an invalid <a href="qcontactmanager.html">QContactManager</a> in return. Any error should be stored in the supplied <i>error</i> reference.</p>
<p>This function was introduced in Qt Mobility 1.0.</p>

<p>This function should return a unique string that identifies the engines provided by this factory.</p>
<p>Typically this would be of the form "com.nokia.qt.contacts.engines.memory", with the appropriate domain and engine name substituted.</p>
<p>This function was introduced in Qt Mobility 1.0.</p>

<p>This function should return a list of versions of the engine which this factory can instantiate.</p>
