void	init(SpacecraftState s0, AbsoluteDate t) Initialize step handler at the start of a propagation.

Method Detail

init

void init(SpacecraftState s0,
        AbsoluteDate t)
          throws PropagationException

Initialize step handler at the start of a propagation.

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

Parameters:

s0 - initial state

t - target time for the integration

Throws:

PropagationException - if step handler cannot be initialized

handleStep

void handleStep(SpacecraftState currentState,
              boolean isLast)
                throws PropagationException

Handle the current step.

Parameters:

currentState - current state at step time

isLast - if true, this is the last integration step

Throws:

PropagationException - if step cannot be handled
