Example 1 with ODEStepHandler

use of org.hipparchus.ode.sampling.ODEStepHandler in project Orekit by CS-SI.

the class DSSTPropagator method afterIntegration.

/**
 * {@inheritDoc}
 */
@Override
protected void afterIntegration() throws OrekitException {
    // remove the special short periodics step handler if added before
    if (!isMeanOrbit()) {
        final List<ODEStepHandler> preserved = new ArrayList<ODEStepHandler>();

        for (final ODEStepHandler sp : integrator.getStepHandlers()) {
            if (!(sp instanceof ShortPeriodicsHandler)) {
                preserved.add(sp);
            }
        }
        // clear the list
        integrator.clearStepHandlers();
        // add back the step handlers that were important for the user
        for (final ODEStepHandler sp : preserved) {
