Inherits: <a href="../kio/KIO.SlaveBase.html">KIO.SlaveBase</a><br />
Namespace: <a href="../kio/KIO.html">KIO</a><br />
<h2>Detailed Description</h2>
<p>There are two classes that specifies the protocol between application (job)
and kioslave. SlaveInterface is the class to use on the application end,
SlaveBase is the one to use on the slave end.
</p>
<p>
Slave implementations should simply inherit SlaveBase
</p>
<p>
A call to foo() results in a call to slotFoo() on the other end.
