Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`PositionAngleType`	`getCachedPositionAngleType()`	Get the cached `PositionAngleType`.
`boolean`	`hasNonKeplerianRates()`	Tells whether the instance holds rates (first-order time derivatives) for dependent variables that are incompatible with Keplerian motion.
`PositionAngleBased`	`withKeplerianRates()`	Create a new instance such that `hasNonKeplerianRates()` is false.

- Method Detail
  - getCachedPositionAngleType
```
PositionAngleType getCachedPositionAngleType()
```
    Get the cached PositionAngleType.
    
    Returns:
    
    cached type of position angle
  - hasNonKeplerianRates
```
boolean hasNonKeplerianRates()
```
    Tells whether the instance holds rates (first-order time derivatives) for dependent variables that are incompatible with Keplerian motion.
    
    Returns:
    
    true if and only if holding non-Keplerian rates
    
    Since:
    
    13.0
  - withKeplerianRates
```
PositionAngleBased withKeplerianRates()
```
    Create a new instance such that hasNonKeplerianRates() is false.
    
    Returns:
    
    new object without rates
