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.

Definition at line 78 of file ZoneArray.hpp.

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 ( StelProjectorP  projector, class StelRenderer *  renderer, 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 >, BigStarCatalogExtension::SpecialZoneArray< Star1 >, and BigStarCatalogExtension::SpecialZoneArray< BigStarCatalogExtension::Star1 >.

unsigned int BigStarCatalogExtension::ZoneArray::getNrOfStars ( ) const

inline

Get the total number of stars in this catalog.

Definition at line 94 of file ZoneArray.hpp.

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

Definition at line 110 of file ZoneArray.hpp.

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

staticprotected

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

Pure virtual method. See subclass implementation.

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

virtual void BigStarCatalogExtension::ZoneArray::updateHipIndex ( HipIndexStruct  hipIndex[] ) const

inlinevirtual

Dummy method that does nothing. See subclass implementation.

Reimplemented in BigStarCatalogExtension::HipZoneArray.

Definition at line 97 of file ZoneArray.hpp.
