Constructor Detail

DateBasedManeuverTriggers

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)

DateBasedManeuverTriggers

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)

Since:

11.1

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:

the duration of the maneuver (s)

convertIntervalDetector

protected <D extends FieldEventDetector<S>,S extends CalculusFieldElement<S>> FieldAbstractDetector<D,S> convertIntervalDetector(Field<S> field,
                                                                                                                                 ParameterDrivenDateIntervalDetector detector)

Convert a primitive firing intervals detector into a field firing intervals detector.

There is not need to set up withMaxCheck, withThreshold, or withHandler in the converted detector, this will be done by caller.

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>>
         FieldAbstractDetector<D, S> 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());

         final FieldAbstractDetector<D, S> converted = (FieldAbstractDetector<D, S>) new FieldXyzDetector<>(date, param);
         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 maneuver triggers parameter drivers.

Returns:

maneuver triggers parameter drivers
