<p>Sources that represent physical devices should implement this interface.
It exposes the ability to eject the device, and also can be used to
implement some <a class="link" href="RBSource.html" title="RBSource"><span class="type">RBSource</span></a> methods by using details from a <a href="/usr/share/gtk-doc/html/gio/GVolume.html#GVolume-struct"><span class="type">GVolume</span></a> or
<a href="/usr/share/gtk-doc/html/gio/GMount.html#GMount-struct"><span class="type">GMount</span></a> accessed via 'volume' and 'mount' properties on the source object.
Devices that are not based on a <a href="/usr/share/gtk-doc/html/gio/GVolume.html#GVolume-struct"><span class="type">GVolume</span></a> or <a href="/usr/share/gtk-doc/html/gio/GMount.html#GMount-struct"><span class="type">GMount</span></a> can still use the
interface, but they must provide implementations of the <em class="parameter"><code>can_eject</code></em>
