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.

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

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
