<p><b>Nouvelle page</b></p><div>== What is an Event ? ==<br />
<br />
An [{{JavaDoc4.5.1}}/fr/cnes/sirius/patrius/propagation/events/EventDetector.html EventDetector] corresponds to an object that will allow to a propagator to determine when this event will occurred.<br />
<br />
<font color=#556B2F>'''PATRIUS'''</font> will already propose a great amount of predefined events (anomaly, <font color=#FF8C00 title="Argument Of Latitude">AOL</font>, altitude, eclipse, ...). These events may be called with "by default" values or may be customized by defining:<br />
* its maximum check interval (in seconds)<br />
* the threshold value below which the convergence is acquired (in seconds)<br />
* the fact that the event will be checked several time or not.<br />
<br />
The following code example shows how to define an anomaly detector with all these possibilities.<br />

== Using AbstractDetector class ==<br />
<br />
If you have not found a predefined event detector into the <font color=#556B2F>'''PATRIUS'''</font> list, you can build yourself you own detector using the [{{JavaDoc4.5.1}}/fr/cnes/sirius/patrius/propagation/events/AbstractDetector.html AbstractDetector] class.<br />
<br />
In such a case, you will have to redefined:<br />
* <font color=#4169E1>eventOccurred()</font> method ; when the event has occured, this method will be called by the propagator and will return the appropriate action<br />
* <font color=#4169E1>g()</font> method ; this method will return a double value which trigger the event when it will reach zero (+/- the threshold)<br />
* <font color=#4169E1>shouldBeRemoved()</font> method<br />
<br />

<br />
== Using EventDetector interface ==<br />
<br />
if you want to customize deeper your event detector, rather than to use AbstractDetector class, you may use EventDetector interface.<br />
<br />
In such a case, you will have to redefined:<br />
* <font color=#4169E1>eventOccurred()</font> method ; when the event has occured, this method will be called by the propagator and will return the appropriate action<br />
* <font color=#4169E1>getMaxCheckInterval()</font> method ; this method will return a double value which trigger the event when it will reach zero (+/- the threshold)<br />
* <font color=#4169E1>getMaxIterationCount()</font> method<br />
* <font color=#4169E1>getSlopeSelection()</font> method<br />
* <font color=#4169E1>getThreshold()</font> method<br />
* <font color=#4169E1>init()</font> method<br />
* <font color=#4169E1>resetState()</font> method<br />
* <font color=#4169E1>shouldBeRemoved()</font> method<br />
