Method Summary

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.
T	withCachedPositionAngleType(PositionAngleType positionAngleType)	Creates a new instance with the provided type used for caching.
T	withKeplerianRates()	Creates a new instance such that hasNonKeplerianRates() is false.

Method Details

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

T withKeplerianRates()

Creates a new instance such that hasNonKeplerianRates() is false.

Returns:

new object without rates

Since:

13.0

withCachedPositionAngleType

T withCachedPositionAngleType(PositionAngleType positionAngleType)

Creates a new instance with the provided type used for caching.

Parameters:

positionAngleType - position angle type to use for caching value

Returns:

new object

Since:

13.0
