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 76 of file ZoneArray.hpp.

Constructor & Destructor Documentation

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* 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 ZoneArray::draw ( StelPainter *  sPainter, int  index, bool  is_inside, const RCMag *  rcmag_table, int  limitMagIndex, StelCore *  core, int  maxMagStarName, float  names_brightness, const QVector< SphericalCap > &  boundingCaps  ) const

pure virtual

Pure virtual method. See subclass implementation.

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

unsigned int ZoneArray::getNrOfStars ( ) const

inline

Get the total number of stars in this catalog.

Definition at line 92 of file ZoneArray.hpp.

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

Initialize the ZoneData struct at the given index.

bool 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 109 of file ZoneArray.hpp.

static bool 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 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 SpecialZoneArray< Star >, SpecialZoneArray< Star2 >, SpecialZoneArray< Star3 >, and SpecialZoneArray< Star1 >.

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

inlinevirtual

Dummy method that does nothing. See subclass implementation.

Reimplemented in HipZoneArray.

Definition at line 95 of file ZoneArray.hpp.

Member Data Documentation

const QString ZoneArray::fname

File path of the catalog.

Definition at line 117 of file ZoneArray.hpp.

const int ZoneArray::level

Level in StelGeodesicGrid.

Definition at line 120 of file ZoneArray.hpp.

const int ZoneArray::mag_min

Lower bound of magnitudes in this level. Units: millimag. May be negative for brightest stars.

Definition at line 123 of file ZoneArray.hpp.

const int ZoneArray::mag_range

Range of magnitudes in this level. Units: millimags.

Definition at line 126 of file ZoneArray.hpp.

const int ZoneArray::mag_steps

Number of steps used to describe values in mag_range. Always positive. Individual stars have their mag entries from 0..mag_steps.

Definition at line 129 of file ZoneArray.hpp.
