<h2 id="details">Detailed Description</h2>
<p>The <a href="qsensormanager.html">QSensorManager</a> class handles registration and creation of sensor backends.</p>
<p>Sensor plugins register backends using the <a href="qsensormanager.html#registerBackend">registerBackend</a>() function.</p>
<p>When <a href="qsensor.html#connectToBackend">QSensor::connectToBackend</a>() is called, the <a href="qsensormanager.html#createBackend">createBackend</a>() function will be called.</p>

<p>Create a backend for <i>sensor</i>. Returns null if no suitable backend exists.</p>

<p>Returns true if the backend identified by <i>type</i> and <i>identifier</i> is registered.</p>
<p>This is a convenience method that helps out plugins doing dynamic registration.</p>
<!-- @@@isBackendRegistered -->
<!-- $$$registerBackend[overload1]$$$registerBackendconstQByteArray&constQByteArray&QSensorBackendFactory* -->

<p>Register a sensor for <i>type</i>. The <i>identifier</i> must be unique.</p>
<p>The <i>factory</i> will be asked to create instances of the backend.</p>
<!-- @@@registerBackend -->
<!-- $$$setDefaultBackend[overload1]$$$setDefaultBackendconstQByteArray&constQByteArray& -->

<p>Sets or overwrite the sensor <i>type</i> with the backend <i>identifier</i>.</p>
<!-- @@@setDefaultBackend -->
<!-- $$$unregisterBackend[overload1]$$$unregisterBackendconstQByteArray&constQByteArray& -->

<p>Unregister the backend for <i>type</i> with <i>identifier</i>.</p>
<p>Note that this only prevents new instance of the backend from being created. It does not invalidate the existing instances of the backend. The backend code should handle the disappearance of the underlying hardware itself.</p>
