        public DateBasedManeuverTriggers​(AbsoluteDate date,
                                 double duration)
        Simple constructor.
        Parameters:
        date - start (or end) data of the maneuver
        duration - maneuver duration (if positive, maneuver is from date to date + duration, if negative, maneuver will be from date - duration to date)

        public DateBasedManeuverTriggers​(String name,
                                 AbsoluteDate date,
                                 double duration)
        Simple constructor.
        Parameters:
        name - name of the trigger (used as prefix for start and stop parameters drivers)
        date - start (or end) data of the maneuver
        duration - maneuver duration (if positive, maneuver is from date to date + duration, if negative, maneuver will be from date - duration to date)

    • Method Detail

      • getName

        public String getName()
        Get the maneuver name.
        Returns:
        the maneuver name

      • getStartDate

        public AbsoluteDate getStartDate()
        Get the start date.
        Returns:
        the start date

      • getEndDate

        public AbsoluteDate getEndDate()
        Get the end date.
        Returns:
        the end date

      • getDuration

        public double getDuration()
        Get the duration of the maneuver (s). duration = endDate - startDate
        Returns:

      • convertIntervalDetector

        protected <D extends FieldEventDetector<S>,​S extends CalculusFieldElement<S>> D convertIntervalDetector​(Field<S> field,
                                                                                                              ParameterDrivenDateIntervalDetector detector)
        Convert a primitive firing intervals detector into a field firing intervals detector.

        The FieldEventDetectionSettings must be set up in conformance with the non-field detector.

        A skeleton implementation of this method to convert some XyzDetector into FieldXyzDetector, considering these detectors are created from a date and a number parameter is: 

        
     protected <D extends FieldEventDetector<S>, S extends CalculusFieldElement<S>>
         D convertIntervalDetector(final Field<S> field, final XyzDetector detector) {

         final FieldAbsoluteDate<S> date  = new FieldAbsoluteDate<>(field, detector.getDate());
         final S                    param = field.getZero().newInstance(detector.getParam());

         D converted = (D) new FieldXyzDetector<>(date, param).withDetectionSettings(field, detector.getDetectionSettings());
         return converted;

     }
        Specified by:
        convertIntervalDetector in class IntervalEventTrigger<ParameterDrivenDateIntervalDetector>
        Type Parameters:
        D - type of the event detector
        S - type of the field elements
        Parameters:
        field - field to which the state belongs
        detector - primitive firing intervals detector to convert
        Returns:
        converted firing intervals detector

      • getParametersDrivers

        public List<ParameterDriver> getParametersDrivers()
        Get the drivers for parameters.
        Returns:
        drivers for parameters
