Detailed Description

A Star (Star1,Star2,Star3,...) cannot be a StelObject.

The additional overhead of having a dynamic type would simply be too much. Therefore the StarWrapper is needed when returning Stars as StelObjects, e.g. for searching, and for constellations. The StarWrapper is destroyed when it is not needed anymore, by utilizing reference counting. So there is no chance that more than a few hundreds of StarWrappers are alive simultanousely. Another reason for having the StarWrapper is to encapsulate the differences between the different kinds of Stars (Star1,Star2,Star3).

Member Function Documentation

◆ getInfoString()

QString StarWrapperBase::getInfoString ( const StelCore core,
const InfoStringGroup &  flags 
) const
overrideprotectedvirtual

StarWrapperBase supports the following InfoStringGroup flags.

  • Name
  • Magnitude
  • RaDecJ2000
  • RaDec
  • AltAzi
  • PlainText
Parameters
corethe StelCore object
flagsa set of InfoStringGroup items to include in the return value.
Returns
a QString containing an HTML encoded description of the StarWrapperBase.

Implements StelObject.

Reimplemented in StarWrapper1.

◆ getObjectType()

QString StarWrapperBase::getObjectType ( void  ) const
inlineoverrideprotectedvirtual

Return object's type.

It should be English lowercase name of the astronomical type of the object. The purpose of this string is a distinction or further refinement over object class name retrieved with getType(): Planet objects can be planets, moons, or even the Sun. The Sun should however return "star". Nebula objects should return their actual type like "open cluster", "galaxy", "nebula", ...
