Constructor & Destructor Documentation

StelObserver::StelObserver ( const StelLocation loc  ) 

Create a new StelObserver instance which is at a fixed Location.

Member Function Documentation

virtual void StelObserver::update ( double   )  [inline, virtual]

Update StelObserver info if needed. Default implementation does nothing.

Reimplemented in SpaceShipObserver.

Vec3d StelObserver::getCenterVsop87Pos ( void   )  const

Get the position of the home planet center in the heliocentric VSOP87 frame in AU.

double StelObserver::getDistanceFromCenter ( void   )  const

Get the distance between observer and home planet center in AU.

virtual const StelLocation& StelObserver::getCurrentLocation (  )  const [inline, virtual]

Get the informations on the current location.

virtual bool StelObserver::isObserverLifeOver (  )  const [inline, virtual]

Get whether the life of this observer is over, and therefore that it should be changed to the next one provided by the getNextObserver() method.

Reimplemented in SpaceShipObserver.

virtual bool StelObserver::isTraveling (  )  const [inline, virtual]

Get whether the location is a moving one.

Reimplemented in SpaceShipObserver.

virtual StelObserver* StelObserver::getNextObserver (  )  const [inline, virtual]

Get the next observer to use once the life of this one is over.

Reimplemented in SpaceShipObserver.
