How to call it
For using the GPOneAxisEllipsoid class, the developer has only to create such an object as is:
ellips = new GPOneAxisEllipsoid("My Ellipsoid");
It is also ,possible to limit the available frames using two possibilities:
- Using a specific constructor:
ellips = new GPOneAxisEllipsoid("My Ellipsoid", GPRefFrame.ITRF, GPRefFrame.TIRF);
- … or using the setAvailableFrames() method:
ellips.setAvailableFrames(GPRefFrame.ITRF, GPRefFrame.TIRF);
We also may initialize the widget with predefined values:
final double REQ = Constants.WGS84_EARTH_EQUATORIAL_RADIUS; final double FLAT = Constants.WGS84_EARTH_FLATTENING; final Frame ITRF = FramesFactory.getITRF(); final ExtendedOneAxisEllipsoid earth = new ExtendedOneAxisEllipsoid(REQ, FLAT, ITRF, "EARTH"); ellips = new GPOneAxisEllipsoid("My Ellipsoid", earth);

In the first case, we will get:
As with the limitation of available frames:
How to use it
To get a [PATRIUS] ExtendedOneAxisEllipsoid object, we will just have to call for the getPatriusObject() method as below:
ExtendedOneAxisEllipsoid extEllips = ellips.getPatriusObject();
How it is stored
Here is the XML format:
<OneAxisEllipsoid name="My_Ellipsoid"> <Real name="sma" unit="km">6.3781363E3</Real> <Real name="flatness">3.3536E-3</Real> <Frame name="frame"> <String name="name">ITRF</String> </Frame> <String name="name">My Ellipsoid</String> </OneAxisEllipsoid>
