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  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_namepath of the star catalog to load from
use_mmapwhether 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
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
