Class RecordAndContinue

java.lang.Object

org.orekit.propagation.events.handlers.RecordAndContinue

All Implemented Interfaces:

EventHandler

public class RecordAndContinue
extends Object
implements EventHandler

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.

Constructor Detail

RecordAndContinue

public RecordAndContinue()

Create a new handler using an ArrayList to store events.

RecordAndContinue

public RecordAndContinue(List<RecordAndContinue.Event> events)

Create a handler using the given collection to store events.

Parameters:

events - collection.

Method Detail

getEvents

public List<RecordAndContinue.Event> 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(SpacecraftState, EventDetector, 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 org.hipparchus.ode.events.Action eventOccurred(SpacecraftState s,
                                                      EventDetector detector,
                                                      boolean increasing)

Description copied from interface: EventHandler

Handle an event.

Specified by:

eventOccurred in interface EventHandler

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
