Member Function Documentation

appendListObject()

void ListComponent::appendListObject

(

SkyObject *

object

)

Add an object to the Object list.

This method is a handy wrapper, which automatically appends the given SkyObject to m_ObjectList and inserts references with all common names (name, name2, longname) into the m_ObjectHash QHash to enable a faster findbyname.

findByName()

SkyObject * ListComponent::findByName ( const QString &  name, bool  exact = true  )

overridevirtual

Search the children of this SkyComponent for a SkyObject whose name matches the argument name the name to be matched exact If true, it will return an exact match, otherwise it can return a partial match.

Returns

a pointer to the SkyObject whose name matches the argument, or a nullptr pointer if no match was found.

Note

This function simply returns the nullptr pointer; it is reimplemented in various sub-classes

Reimplemented from SkyComponent.

objectNearest()

SkyObject * ListComponent::objectNearest ( SkyPoint *  p, double &  maxrad  )

overridevirtual

Find the SkyObject nearest the given SkyPoint.

Look for a SkyObject that is nearer to point p than maxrad. If one is found, then maxrad is reset to the separation of the new nearest object. p pointer to the SkyPoint to search around maxrad reference to current search radius in degrees

Returns

a pointer to the nearest SkyObject

Note

This function simply returns a nullptr pointer; it is reimplemented in various sub-classes.

Reimplemented from SkyComponent.

Reimplemented in StarComponent, and SupernovaeComponent.

update()

void ListComponent::update ( KSNumbers *  num = nullptr )

overridevirtual

Update the sky positions of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of the objects in this component. If the KSNumbers* argument is not nullptr, this function also recomputes precession and nutation for the date in KSNumbers. num Pointer to the KSNumbers object

Note

By default, the num parameter is nullptr, indicating that Precession/Nutation computation should be skipped; this computation is only occasionally required.

Reimplemented from SkyComponent.

Reimplemented in SupernovaeComponent, StarComponent, and SolarSystemListComponent.
