Constructor & Destructor Documentation

◆ LineListIndex()

LineListIndex::LineListIndex ( SkyComposite * parent,
const QString & name = "" )

Constructor Simply set the internal skyMesh, parent, and name.

parentPointer to the parent SkyComponent object
namename of the subclass used for debugging

Definition at line 34 of file linelistindex.cpp.

Member Function Documentation

◆ appendBoth()

void LineListIndex::appendBoth ( const std::shared_ptr< LineList > & lineList)

a convenience method that adds a lineList to both the lineIndex and the polyIndex.

Definition at line 100 of file linelistindex.cpp.

◆ appendLine()

void LineListIndex::appendLine ( const std::shared_ptr< LineList > & lineList)

Typically called from within a subclasses constructors.

Adds the trixels covering the outline of lineList to the lineIndex.

Definition at line 63 of file linelistindex.cpp.

◆ appendPoly()

void LineListIndex::appendPoly ( const std::shared_ptr< LineList > & lineList)

Typically called from within a subclasses constructors.

Adds the trixels covering the full lineList to the polyIndex.

Definition at line 82 of file linelistindex.cpp.

◆ draw()

void LineListIndex::draw ( SkyPainter * skyp)

The top level draw routine.

Draws all the LineLists for any subclass in one fell swoop which minimizes some of the loop overhead. Overridden by MilkWay so it can decide whether to draw outlines or filled. Therefore MilkyWay does not need to override preDraw(). The MilkyWay draw() routine calls all of the more specific draw() routines below.

Implements SkyComponent.

Reimplemented in MilkyWay.

Definition at line 158 of file linelistindex.cpp.

◆ drawBuffer()

virtual MeshBufNum_t LineListIndex::drawBuffer ( )

a callback overridden by NoPrecessIndex so it can use the drawing code with the non-reverse-precessed mesh buffer.

Reimplemented in NoPrecessIndex.

Definition at line 142 of file linelistindex.h.

◆ drawFilled()

void LineListIndex::drawFilled ( SkyPainter * skyp)

Draws all the lines in m_listList as filled polygons in float mode.

Definition at line 203 of file linelistindex.cpp.

◆ drawLines()

void LineListIndex::drawLines ( SkyPainter * skyp)

Draws all the lines in m_listList as simple lines in float mode.

Definition at line 180 of file linelistindex.cpp.

◆ getIndexHash()

const IndexHash & LineListIndex::getIndexHash ( LineList * lineList)

Returns an IndexHash from the SkyMesh that contains the set of trixels that cover lineList.

Overridden by SkipListIndex so it can pass SkyMesh an IndexHash indicating which line segments should not be indexed

lineListcontains the list of points to be covered.

Reimplemented in ConstellationLines, and MilkyWay.

Definition at line 42 of file linelistindex.cpp.

◆ intro()

void LineListIndex::intro ( )

displays a message that we are loading m_name.

Also prints out the message if skyMesh debug is greater than zero.

Definition at line 234 of file linelistindex.cpp.

◆ JITupdate()

void LineListIndex::JITupdate ( LineList * lineList)

this is called from within the draw routines when the updateID of the lineList is stale.

It is virtual because different subclasses have different update routines. NoPrecessIndex doesn't precess in the updates and ConstellationLines must update its points as stars, not points. that doesn't precess the points.

Reimplemented in ConstellationLines, and NoPrecessIndex.

Definition at line 129 of file linelistindex.cpp.

◆ label()

virtual LineListLabel * LineListIndex::label ( )

Definition at line 161 of file linelistindex.h.

◆ listList()

LineListList LineListIndex::listList ( ) const

Definition at line 163 of file linelistindex.h.

◆ name()

QString LineListIndex::name ( ) const

retrieve name of object

Definition at line 84 of file linelistindex.h.

◆ preDraw()

void LineListIndex::preDraw ( SkyPainter * skyp)

Gives the subclasses access to the top of the draw() method.

Typically used for setting the QPen, etc. in the QPainter being passed in. Defaults to setting a thin white pen.

Reimplemented in ConstellationLines, Equator, EquatorialCoordinateGrid, HorizontalCoordinateGrid, LocalMeridianComponent, and CoordinateGrid.

Definition at line 153 of file linelistindex.cpp.

◆ reindexLines()

void LineListIndex::reindexLines ( )

as the name says, recreates the lineIndex using the LineLists in the previous index.

Since we are indexing everything at J2000 this is only used by ConstellationLines which needs to reindex because of the proper motion of the stars.

Definition at line 108 of file linelistindex.cpp.

◆ removeLine()

void LineListIndex::removeLine ( const std::shared_ptr< LineList > & lineList)

Definition at line 47 of file linelistindex.cpp.

◆ skipList()

SkipHashList * LineListIndex::skipList ( LineList * lineList)

Also overridden by SkipListIndex.

Controls skipping inside of the draw() routines. The default behavior is to simply return a null pointer.

FIXME: I don't think that the SkipListIndex class even exists – hdevalence

Reimplemented in MilkyWay.

Definition at line 174 of file linelistindex.cpp.

◆ skyMesh()

SkyMesh * LineListIndex::skyMesh ( )

Returns the SkyMesh object.

Definition at line 99 of file linelistindex.h.

◆ summary()

void LineListIndex::summary ( )

prints out some summary statistics if the skyMesh debug is greater than 1.

Definition at line 241 of file linelistindex.cpp.
