Typedefs
typedef QSharedPointer< Quasar >	QuasarP

Detailed Description

The Quasars plugin provides visualization of some quasars brighter than 16 visual magnitude. A catalogue of quasars compiled from "Quasars and Active Galactic Nuclei" (13th Ed.) (Veron+ 2010).

Quasars Catalog

The quasars catalog is stored on the disk in JSON format, in a file named "quasars.json". A default copy is embedded in the plug-in at compile time. A working copy is kept in the user data directory.

Configuration

The plug-ins' configuration data is stored in Stellarium's main configuration file (section [Quasars]).

Constructor & Destructor Documentation

◆ Quasar()

Quasar::Quasar ( const QVariantMap & map )

Parameters

id	The official designation for a quasar, e.g. "RXS J00066+4342"

Member Function Documentation

◆ getID()

QString Quasar::getID ( void ) const

inlineoverridevirtual

Returns a unique identifier for this object.

The ID should be unique for all objects of the same type, but may freely conflict with IDs of other types, so getType() must also be tested.

With this it should be possible to at least identify the same object in a different instance of Stellarium running the same version, but it would even be better if the ID provides some degree of forward-compatibility. For some object types (e.g. planets) this may simply return getEnglishName(), but better candidates may be official designations or at least (stable) internal IDs.

An object may have multiple IDs (different catalog numbers, etc). StelObjectMgr::searchByID() should search through all ID variants, but this method only returns one of them.

Implements StelObject.

◆ getInfoMap()

QVariantMap Quasar::getInfoMap ( const StelCore * core ) const

overridevirtual

Return a map like StelObject::getInfoMap(), but with a few extra tags also available in getMap().

◆ getInfoString()

		const InfoStringGroup &	flags
	)		const

overridevirtual

Get an HTML string to describe the object.

Parameters

core	A pointer to the core @flags a set of flags with information types to include.

Implements StelObject.

◆ getMap()

Get a QVariantMap which describes the Quasar.

◆ getObjectType()

QString Quasar::getObjectType ( void ) const

inlineoverridevirtual

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", ...
