T - type of the field elementspublic class FieldAltitudeDetector<T extends org.hipparchus.CalculusFieldElement<T>> extends FieldAbstractDetector<FieldAltitudeDetector<T>,T>
This class finds altitude events (i.e. satellite crossing a predefined altitude level above ground).
The default implementation behavior is to continue propagation when ascending and to stop
propagation when descending. This can be changed by calling
FieldAbstractDetector.withHandler(FieldEventHandler) after construction.

This simple constructor takes default values for maximal checking
interval (FieldAbstractDetector.DEFAULT_MAXCHECK) and convergence threshold
(FieldAbstractDetector.DEFAULT_THRESHOLD).
altitude - threshold altitude valuebodyShape - body shape with respect to which altitude should be evaluatedpublic FieldAltitudeDetector(T maxCheck, T altitude, BodyShape bodyShape)
This simple constructor takes default value for convergence threshold
(FieldAbstractDetector.DEFAULT_THRESHOLD).
The maximal interval between altitude checks should be smaller than the half duration of the minimal pass to handle, otherwise some short passes could be missed.
maxCheck - maximal checking interval (s)altitude - threshold altitude value (m)bodyShape - body shape with respect to which altitude should be evaluatedpublic FieldAltitudeDetector(T maxCheck, T threshold, T altitude, BodyShape bodyShape)
The maximal interval between altitude checks should be smaller than the half duration of the minimal pass to handle, otherwise some short passes could be missed.

This constructor is not public as users are expected to use the builder
API with the various withXxx() methods to set up the instance
in a readable manner without using a huge amount of parameters.
