Constructor & Destructor Documentation

◆ StarBlock()

StarBlock::StarBlock ( int  nstars = 100)
explicit

Constructor.

Initializes values of various parameters and creates nstars number of stars

Parameters
nstarsNumber of stars to hold in this StarBlock

Definition at line 33 of file starblock.cpp.

Member Function Documentation

◆ addStar()

StarObject * StarBlock::addStar ( const StarData data)

Initialize another star with data.

FIXME: StarObject::init doesn't reset object name(s). It shouldn't be issue since stars which are swapped in/out do not have names.

Parameters
datadata to initialize star with.
Returns
pointer to star initialized with data. nullptr if block is full.

Definition at line 85 of file starblock.cpp.

◆ contents()

QVector<StarBlockEntry>& StarBlock::contents ( )
inline
Returns
a reference to the internal container of this
Note
This is bad – is there a way of providing non-const access to the list's elements without allowing altering of the list alone?

Definition at line 108 of file starblock.h.

◆ getBrightMag()

float StarBlock::getBrightMag ( ) const
inline

Return the magnitude of the brightest star in this StarBlock.

Returns
Magnitude of the brightest star

Definition at line 116 of file starblock.h.

◆ getFaintMag()

float StarBlock::getFaintMag ( ) const
inline

Return the magnitude of the faintest star in this StarBlock.

Returns
Magnitude of the faintest star

Definition at line 123 of file starblock.h.

◆ getStarCount()

int StarBlock::getStarCount ( ) const
inline

Return the number of stars currently filled in this StarBlock.

Returns
Number of stars filled in this StarBlock

Definition at line 130 of file starblock.h.

◆ isFull()

bool StarBlock::isFull ( ) const
inline

Returns true if the StarBlock is full.

Returns
true if full, false if not full

Definition at line 81 of file starblock.h.

◆ reset()

void StarBlock::reset ( )

Reset this StarBlock's data, for reuse of the StarBlock.

Definition at line 43 of file starblock.cpp.

◆ size()

int StarBlock::size ( ) const
inline

Return the capacity of this StarBlock.

This is different from nStars. While nStars indicates the number of stars that this StarBlock actually holds, this method returns the number of stars for which we have allocated memory. Thus, this method should return a number >= nStars.

Returns
The number of stars that this StarBlock can hold

Definition at line 92 of file starblock.h.

◆ star()

StarBlockEntry* StarBlock::star ( int  i)
inline

Return the i-th star in this StarBlock.

Parameters
iIndex of StarBlock to return
Returns
A pointer to the i-th StarObject
