Method Summary

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

- Method Detail
  - getCachedPositionAngleType
```
PositionAngleType getCachedPositionAngleType()
```
    Get the cached PositionAngleType.
    
    Returns:
    
    cached type of position angle
  - hasRates
```
boolean hasRates()
```
    Tells whether the instance holds rates (first-order time derivatives) for dependent variables.
    
    Returns:
    
    true if and only if holding rates
  - removeRates
```
PositionAngleBased removeRates()
```
    Create a new instance such that hasRates() is false.
    
    Returns:
    
    new object without rates
