Constructor Detail

FieldLongitudeExtremumDetector

public FieldLongitudeExtremumDetector(Field<T> field,
                                      BodyShape body)

Build a new detector.

The new instance uses default values for maximal checking interval (FieldAbstractDetector.DEFAULT_MAX_CHECK) and convergence threshold (FieldAbstractDetector.DEFAULT_THRESHOLD).

Parameters:

field - the type of numbers to use.

body - body on which the longitude is defined

FieldLongitudeExtremumDetector

public FieldLongitudeExtremumDetector(FieldEventDetectionSettings<T> detectionSettings,
                                      FieldEventHandler<T> handler,
                                      BodyShape body)

Constructor with full parameters.

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.

Parameters:

detectionSettings - event detection settings

handler - event handler to call at event occurrences

body - body on which the longitude is defined

Since:

13.0

Method Detail

getEventFunction

public LongitudeExtremumEventFunction getEventFunction()

Get the event function. It defines g both for double and Field.

Specified by:

getEventFunction in interface FieldEventDetector<T extends CalculusFieldElement<T>>

Overrides:

getEventFunction in class FieldAbstractDetector<FieldLongitudeExtremumDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>

Returns:

event function

create

protected FieldLongitudeExtremumDetector<T> create(FieldEventDetectionSettings<T> detectionSettings,
                                                   FieldEventHandler<T> newHandler)

Build a new instance.

Specified by:

create in class FieldAbstractDetector<FieldLongitudeExtremumDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>

Parameters:

detectionSettings - detection settings

newHandler - event handler to call at event occurrences

Returns:

a new instance of the appropriate sub-type

g

public T g(FieldSpacecraftState<T> s)

Compute the value of the switching function. This function must be continuous (at least in its roots neighborhood), as the integrator will need to find its roots to locate the events.

Parameters:

s - the current state information: date, kinematics, attitude

Returns:

value of the switching function

toEventDetector

public LongitudeExtremumDetector toEventDetector(EventHandler eventHandler)

Description copied from class: FieldAbstractDetector

Build non-Field instance.

Overrides:

toEventDetector in class FieldAbstractDetector<FieldLongitudeExtremumDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>

Parameters:

eventHandler - event handler

Returns:

event detector
