Example 6 with RecordAndContinue

use of org.orekit.propagation.events.handlers.RecordAndContinue in project Orekit by CS-SI.

the class CloseEventsAbstractTest method testFastSwitching.

/**
 * test the g function switching with a period shorter than the tolerance. We don't
 * need to find any of the events, but we do need to not crash. And we need to
 * preserve the alternating increasing / decreasing sequence.
