Triggering API</title><shortdesc>The Location Triggering API enables a client application to create
and manage location based triggers. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>Location based triggers notify a client application when a device enters
or leaves a specified geographical area. For example, an end user could set
a trigger so that their device notifies them when they are in the vicinity
of a specific train station. </p>
<p>A trigger has various attributes, including a triggering condition and
a system reaction. The triggering condition determines when the trigger is
fired. The system reaction determines how the client application is notified
when the triggering condition is met.</p>
<p>Typical use cases include:</p>
<ul>
<li><p>Creating a trigger</p></li>
<li><p>Modifying a trigger</p></li>
<li><p>Deleting a trigger</p></li>
<li><p>Handling a trigger firing event.</p></li>
</ul>
<p>For detailed information about the Location Triggering API, see the Location
Triggering API Specification document.</p>
