Constructor Detail

AbstractBodyAttraction

protected AbstractBodyAttraction(CelestialBody body)

Simple constructor.

Parameters:

body - the third body to consider

Method Detail

getBodyName

public String getBodyName()

Getter for the body's name.

Returns:

the body's name

getBody

protected CelestialBody getBody()

Protected getter for the body.

Returns:

the third body considered

dependsOnPositionOnly

public boolean dependsOnPositionOnly()

Check if force model depends on position only at a given, fixed date.

Specified by:

dependsOnPositionOnly in interface ForceModel

Returns:

true if force model depends on position only, false if it depends on velocity, either directly or due to a dependency on attitude

getParametersDrivers

public List<ParameterDriver> getParametersDrivers()

Get the drivers for parameters.

Specified by:

getParametersDrivers in interface ParameterDriversProvider

Returns:

drivers for parameters
