All Implemented Interfaces:

AdditionalDataProvider<double[]>
```
public abstract class AbstractStateModifier
extends Object
implements AdditionalDataProvider<double[]>
```
Abstract base class for modifying state during propagation.
This class is a specialized implementation of AdditionalDataProvider with a name set to the empty string and returning a null additional state.

Beware that changing the state undercover from the propagator may have many side effects. Using this class should therefore be done cautiously.

12.1

- Method Detail
  - getName
```
public String getName()
```
    Get the name of the additional data.
    If a provider just modifies one of the basic elements (orbit, attitude or mass) without adding any new data, it should return the empty string as its name.
    
    Specified by:
    
    getName in interface AdditionalDataProvider<double[]>
    
    Returns:
    
    name of the additional data (names containing "orekit" with any case are reserved for the library internal use)
  - getAdditionalData
```
public double[] getAdditionalData(SpacecraftState state)
```
    Get the additional data.
    
    Specified by:
    
    getAdditionalData in interface AdditionalDataProvider<double[]>
    
    Parameters:
    
    state - spacecraft state to which additional data should correspond
    
    Returns:
    
    additional state corresponding to spacecraft state
  - update
```
public SpacecraftState update(SpacecraftState state)
```
    Update a state.
    
    Specified by:
    
    update in interface AdditionalDataProvider<double[]>
    
    Parameters:
    
    state - spacecraft state to update
    
    Returns:
    
    updated state
  - change
```
public abstract SpacecraftState change(SpacecraftState state)
```
    Change main state.
    
    Parameters:
    
    state - spacecraft state to change
    
    Returns:
    
    changed state
