Class FieldAdapterDetector<T extends org.hipparchus.CalculusFieldElement<T>>

java.lang.Object

org.orekit.propagation.events.FieldAdapterDetector<T>

Type Parameters:

T - type of the field element

All Implemented Interfaces:

FieldEventDetector<T>

public class FieldAdapterDetector<T extends org.hipparchus.CalculusFieldElement<T>>
extends Object
implements FieldEventDetector<T>

Base class for adapting an existing detector.

This class is intended to be a base class for changing behaviour of a wrapped existing detector. This base class delegates all its methods to the wrapped detector. Classes extending it can therefore override only the methods they want to change.

Since:

12.0

Constructor Detail

FieldAdapterDetector

public FieldAdapterDetector(FieldEventDetector<T> detector)

Build an adaptor wrapping an existing detector.

Parameters:

detector - detector to wrap

Method Detail

getDetector

public FieldEventDetector<T> getDetector()

Get the wrapped detector.

Returns:

wrapped detector

init

public void init(FieldSpacecraftState<T> s0,
                 FieldAbsoluteDate<T> t)

Initialize event handler at the start of a propagation.

This method is called once at the start of the propagation. It may be used by the event handler to initialize some internal data if needed.

The default implementation does nothing

Specified by:

init in interface FieldEventDetector<T extends org.hipparchus.CalculusFieldElement<T>>

Parameters:

s0 - initial state

t - target time for the integration

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.

Specified by:

g in interface FieldEventDetector<T extends org.hipparchus.CalculusFieldElement<T>>

Parameters:

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

Returns:

value of the switching function

getThreshold

public T getThreshold()

Get the convergence threshold in the event time search.

Specified by:

getThreshold in interface FieldEventDetector<T extends org.hipparchus.CalculusFieldElement<T>>

Returns:

convergence threshold (s)

getMaxCheckInterval

public FieldAdaptableInterval<T> getMaxCheckInterval()

Get maximal time interval between switching function checks.

Specified by:

getMaxCheckInterval in interface FieldEventDetector<T extends org.hipparchus.CalculusFieldElement<T>>

Returns:

maximal time interval (s) between switching function checks

getMaxIterationCount

public int getMaxIterationCount()

Get maximal number of iterations in the event time search.

Specified by:

getMaxIterationCount in interface FieldEventDetector<T extends org.hipparchus.CalculusFieldElement<T>>

Returns:

maximal number of iterations in the event time search

getHandler

public FieldEventHandler<T> getHandler()

Get the handler.

Specified by:

getHandler in interface FieldEventDetector<T extends org.hipparchus.CalculusFieldElement<T>>

Returns:

event handler to call at event occurrences
