Constructor Details

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

DateBasedManeuverTriggers

public DateBasedManeuverTriggers(String name,
 AbsoluteDate date,
 double duration,
 EventDetectionSettings detectionSettings)

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)

detectionSettings - date detection settings (warning: choose with care, as poor settings might miss the maneuver)

Since:

13.0

Method Details

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 <S extends CalculusFieldElement<S>>
FieldParameterDrivenDateIntervalDetector<S> 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 default implementation is provided but might need to be overridden in specific cases.

Overrides:

convertIntervalDetector in class IntervalEventTrigger<ParameterDrivenDateIntervalDetector>

Type Parameters:

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.

By default, no drivers is defined.

Returns:

drivers for parameters
