Method Summary

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`finish(SpacecraftState finalState)`	Method called at end of propagation.
`Vector3D`	`getImpulse(SpacecraftState state, boolean isForward)`	Method returning the impulse to be applied.
`default void`	`init(SpacecraftState initialState, AbsoluteDate targetDate)`	Method called at start of propagation.
`static ImpulseProvider`	`of(Vector3D forwardImpulse)`	Get a provider returning a given vector for forward propagation and its opposite for backward.

- Method Detail
  - getImpulse
```
Vector3D getImpulse(SpacecraftState state,
                    boolean isForward)
```
    Method returning the impulse to be applied.
    
    Parameters:
    
    state - state before the maneuver is applied if isForward is true, after otherwise
    
    isForward - flag on propagation direction
    
    Returns:
    
    impulse in satellite's frame
  - init
```
default void init(SpacecraftState initialState,
                  AbsoluteDate targetDate)
```
    Method called at start of propagation.
    
    Parameters:
    
    initialState - state at start of propagation
    
    targetDate - target end date
  - finish
```
default void finish(SpacecraftState finalState)
```
    Method called at end of propagation.
    
    Parameters:
    
    finalState - state at end of propagation
  - of
```
static ImpulseProvider of(Vector3D forwardImpulse)
```
    Get a provider returning a given vector for forward propagation and its opposite for backward. The attitude comes from the state directly.
    
    Parameters:
    
    forwardImpulse - forward impulse vector
    
    Returns:
    
    constant provider
