Package org.orekit.propagation.events.handlers

Class FieldRecordAndContinue<T extends CalculusFieldElement<T>>

java.lang.Object

org.orekit.propagation.events.handlers.FieldRecordAndContinue<T>

Type Parameters:

T - type of the field element

All Implemented Interfaces:

FieldEventHandler<T>

public class FieldRecordAndContinue<T extends CalculusFieldElement<T>>
extends Object
implements FieldEventHandler<T>

Handler that will record every time an event occurs and always return Action.CONTINUE.

As this handler stores all observed events it may consume large amounts of memory depending on the duration of propagation and the frequency of events.

Since:

9.3

Constructor Details

FieldRecordAndContinue

public FieldRecordAndContinue()

Create a new handler using an ArrayList to store events.

FieldRecordAndContinue

public FieldRecordAndContinue(List<FieldRecordAndContinue.Event<T>> events)

Create a handler using the given collection to store events.

Parameters:

events - collection.

Method Details

getEvents

public List<FieldRecordAndContinue.Event<T>> getEvents()

Get the events passed to this handler.

Note the returned list of events is in the order the events were passed to this handler by calling eventOccurred(FieldSpacecraftState, FieldEventDetector, boolean). This may or may not be chronological order.

Also not that this method returns a view of the internal collection used to store events and calling any of this handler's methods may modify both the underlying collection and the returned view. If a snapshot of the events up to a certain point is needed create a copy of the returned collection.

Returns:

the events observed by the handler in the order they were observed.

clear

public void clear()

Clear all stored events.

eventOccurred

public Action eventOccurred(FieldSpacecraftState<T> s,
 FieldEventDetector<T> detector,
 boolean increasing)

Description copied from interface: FieldEventHandler

Handle an event.

Specified by:

eventOccurred in interface FieldEventHandler<T extends CalculusFieldElement<T>>

Parameters:

s - SpaceCraft state to be used in the evaluation

detector - object with appropriate type that can be used in determining correct return state

increasing - with the event occurred in an "increasing" or "decreasing" slope direction

Returns:

the Action that the calling detector should pass back to the evaluation system
