Detailed Description

Manages all ZoneData structures of a given StelGeodesicGrid level.

An instance of this class is never created directly; the named constructor returns an instance of one of its subclasses. All it really does is bootstrap the loading process.

Constructor & Destructor Documentation

BigStarCatalogExtension::ZoneArray::ZoneArray	(	const QString &	fname,
		QFile *	file,
		int	level,
		int	mag_min,
		int	mag_range,
		int	mag_steps
	)			`[protected]`

Protected constructor. Initializes fields and does not load anything.

Member Function Documentation

static ZoneArray* BigStarCatalogExtension::ZoneArray::create	(	const QString &	extended_file_name,
		bool	use_mmap
	)			`[static]`

Named public constructor for ZoneArray.

Opens a catalog, reads its header info, and creates a SpecialZoneArray or HipZoneArray for loading.

Parameters:

	extended_file_name	path of the star catalog to load from
	use_mmap	whether or not to mmap the star catalog

Returns:: an instance of SpecialZoneArray or HipZoneArray

virtual void BigStarCatalogExtension::ZoneArray::draw	(	StelPainter *	sPainter,
		int	index,
		bool	is_inside,
		const float *	rcmag_table,
		StelCore *	core,
		unsigned int	maxMagStarName,
		float	names_brightness
	)			const `[pure virtual]`

Pure virtual method. See subclass implementation.

Implemented in BigStarCatalogExtension::SpecialZoneArray< Star >, BigStarCatalogExtension::SpecialZoneArray< Star2 >, BigStarCatalogExtension::SpecialZoneArray< Star3 >, and BigStarCatalogExtension::SpecialZoneArray< Star1 >.

unsigned int BigStarCatalogExtension::ZoneArray::getNrOfStars ( ) const [inline]

Get the total number of stars in this catalog.

void BigStarCatalogExtension::ZoneArray::initTriangle	(	int	index,
		const Vec3f &	c0,
		const Vec3f &	c1,
		const Vec3f &	c2
	)

Initialize the ZoneData struct at the given index.

bool BigStarCatalogExtension::ZoneArray::isInitialized ( void ) const [inline]

Get whether or not the catalog was successfully loaded.

Returns:: true if at least one zone was loaded, otherwise false

static bool BigStarCatalogExtension::ZoneArray::readFile	(	QFile &	file,
		void *	data,
		qint64	size
	)			`[static, protected]`

Load a catalog and display its progress on the splash screen.

Returns:: true if successful, or false if an error occurred

virtual void BigStarCatalogExtension::ZoneArray::searchAround	(	const StelCore *	core,
		int	index,
		const Vec3d &	v,
		double	cosLimFov,
		QList< StelObjectP > &	result
	)			`[pure virtual]`
