<hr/>
<p>I am a service you can add to an application.</p>
<p>I represent some chunk of functionality which may be bound to many or
no event sources. By adding an ApplicationService to an <a
href="twisted.internet.app.Application.html"
class="link"><code>Application</code></a>, it will be notified when the
Application starts and stops (or removes/shuts down the service). See the
<a href="twisted.internet.app.ApplicationService.html#startService"
class="link"><code>startService</code></a> and <a
href="twisted.internet.app.ApplicationService.html#stopService"
class="link"><code>stopService</code></a> calls.</p>
Since services may want to incorporate certain other elements, notably
Perspective Broker (remote invocation) accessibility and authentication,
derivatives of ApplicationService exist in <a
href="twisted.cred.service.Service.html"
class="link"><code>twisted.cred.service</code></a> and <a
href="twisted.spread.pb.Service.html"
class="link"><code>twisted.spread.pb</code></a>. These may be more
suitable for your service than directly subclassing
ApplicationService.
