Interface FieldDetectorModifier<T extends CalculusFieldElement<T>>

Type Parameters:

T - type of the field element

All Superinterfaces:

FieldEventDetector<T>

All Known Implementing Classes:

public interface FieldDetectorModifier<T extends CalculusFieldElement<T>>
extends FieldEventDetector<T>

Base class for modifying an existing getDetector().

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

Since:

13.0

Method Details

getDetector

FieldEventDetector<T> getDetector()

Getter for wrapped detector.

Returns:

detector

init

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

Initialize event detector at the start of a propagation.

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

The default implementation initializes the handler.

Specified by:

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

Parameters:

s0 - initial state

t - target time for the integration

reset

default void reset(FieldSpacecraftState<T> state,
 FieldAbsoluteDate<T> target)

Reset the event detector during propagation when the state is modified by an event or an additional data provider.

The default implementation does nothing.

Specified by:

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

Parameters:

state - current state

target - target time for the integration

getEventFunction

default EventFunction getEventFunction()

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

Specified by:

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

Returns:

event function

g

default 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 CalculusFieldElement<T>>

Parameters:

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

Returns:

value of the switching function

getHandler

default FieldEventHandler<T> getHandler()

Get the handler.

Specified by:

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

Returns:

event handler to call at event occurrences

finish

default void finish(FieldSpacecraftState<T> state)

This method finalizes the event detector's job.

Specified by:

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

Parameters:

state - state at propagation end

getDetectionSettings

default FieldEventDetectionSettings<T> getDetectionSettings()

Getter for the settings.

Specified by:

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

Returns:

detection settings
