Constructor Details

SecondaryEventLogger

public SecondaryEventLogger(PVCoordinatesProvider secondaryPVCoordinatesProvider,
 Action action)

Constructor.

Parameters:

secondaryPVCoordinatesProvider - provider for secondary trajectory

action - action to return when event occurs

SecondaryEventLogger

public SecondaryEventLogger(PVCoordinatesProvider secondaryPVCoordinatesProvider)

Constructor with default Action (CONTINUE).

Parameters:

secondaryPVCoordinatesProvider - provider for secondary trajectory

Method Details

clearLogs

public void clearLogs()

Method to clear logs.

copyLogs

public List<Pair<AbsolutePVCoordinates,PVCoordinates>> copyLogs()

Method to copy logs.

Returns:

copy of logs

getSecondaryPVCoordinatesProvider

public PVCoordinatesProvider getSecondaryPVCoordinatesProvider()

Getter for the secondary trajectory provider.

Returns:

secondary

init

public void init(SpacecraftState initialState,
 AbsoluteDate target,
 EventDetector detector)

Description copied from interface: EventHandler

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 EventHandler

Parameters:

initialState - initial state

target - target date for the propagation

detector - event detector related to the event handler

finish

public void finish(SpacecraftState finalState,
 EventDetector detector)

Description copied from interface: EventHandler

This method finalizes the event handler's job.

The default implementation does nothing

Specified by:

finish in interface EventHandler

Parameters:

finalState - state at propagation end

detector - event detector related to the event handler

eventOccurred

public 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
