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.

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

Dummy method that does nothing. See subclass implementation.

Reimplemented in BigStarCatalogExtension::HipZoneArray.
