public class FieldDateDetector<T extends RealFieldElement<T>> extends FieldAbstractDetector<FieldDateDetector<T>,T> implements FieldTimeStamped<T>
This class finds date events (i.e. occurrence of some predefined dates).
As of version 5.1, it is an enhanced date detector:
FieldDateDetector(RealFieldElement, RealFieldElement, FieldTimeStamped...)
)addEventDate(FieldAbsoluteDate)
)The gap between the added dates must be more than the maxCheck.
The default implementation behavior is to stop
propagation at the first event date occurrence. This can be changed by calling
FieldAbstractDetector.withHandler(FieldEventHandler)
after construction.

First event dates are set here, but others can be
added later with addEventDate(FieldAbsoluteDate)
.

public FieldDateDetector(FieldAbsoluteDate<T> target)
This constructor is dedicated to single date detection.
max check interval
is set to 1.0e10, so almost
no other date can be added. Tolerance is set to 1.0e-9.
