Class Catalog2D

java.lang.Object

  +--stsci.sky.Catalog2D

All Implemented Interfaces:

ArcObjCont, java.util.EventListener, java.awt.event.ItemListener

Direct Known Subclasses:

CompassCatalog

public class Catalog2D

extends java.lang.Object

implements ArcObjCont, java.awt.event.ItemListener

This represebts a continer for all stars retreived from a particular Archive at a particular time. * @author This decides which color is used for plotting the points.This will actually call back up to the SkyArea toget x,y positions so stars can do the plotting - this is because the SkyArea knows the coordinate system but the star remembers where it was last time and the Catalog contains the color information

Constructor Summary

Catalog2D()

Catalog2D(SourceArchive arc, SkyArea sky)

Method Summary

void	add(ArchiveObject o)
java.awt.Color	color() The color to use plotting this catalog.
boolean	filter(Star2D s) Apply the criteria to the given star.
Star2D	findNear(int x, int y) Find the star plotted near the given screen coordinates - this came from Hipparcos - it assumes stars are ordered in RA comming from the catalog and does a binary searc based on that assumption.
Star2D	findStar(java.lang.String id)
java.util.Iterator	getStars()
void	init(double a, double d, double r) This gets called when we want to populate the sky.
void	itemStateChanged(java.awt.event.ItemEvent arg0)
void	moveStars(int year)
java.lang.String	name()
void	plot() Plot all Stars matching the criteria.
void	plot(Star2D s, java.awt.Rectangle r) Plot individual Star if it matches criteria.
protected void	replot() Unplot Stars no longer matching the criteria but plot thoose which do.
void	reScale() Scale changed so all stars must have positions recalcuolated * @return void
void	setCol(java.awt.Color c)
void	setCrit(Criteria c)
void	setPlot(boolean v) Plot this catlog or not ? * @param v
void	setPos(Star2D s) Set the X,Y coordinate on screen of the star.
void	setServerSideFilter(boolean v) Apply the criteria on the serverside or not - cuts down data transfer but allows less flexibility in the client.
void	unplot() unplot all stars from this catalogue * @return void

findNear

public Star2D findNear(int x,
                       int y)

Find the star plotted near the given screen coordinates - this came from Hipparcos - it assumes stars are ordered in RA comming from the catalog and does a binary searc based on that assumption. This is done none recursivly. * @param x

Parameters:

y -

Returns:

findStar

public Star2D findStar(java.lang.String id)

color

public java.awt.Color color()

The color to use plotting this catalog. * @return Color

Throws:

-

init

public void init(double a,
                 double d,
                 double r)

This gets called when we want to populate the sky. * @param a

Parameters:

d -

r -

Returns:

void

Throws:

-

setServerSideFilter

public void setServerSideFilter(boolean v)

Apply the criteria on the serverside or not - cuts down data transfer but allows less flexibility in the client. * @param v

Returns:

void

Throws:

-

reScale

public void reScale()

Scale changed so all stars must have positions recalcuolated * @return void

Throws:

-

setPos

public void setPos(Star2D s)

Set the X,Y coordinate on screen of the star. Only needs to be don after a rescale or the first time a star is loaded. * @param s

Returns:

void

Throws:

-

getStars

public java.util.Iterator getStars()

Returns:

Iterator

Throws:

-

filter

public boolean filter(Star2D s)

Apply the criteria to the given star. this is used before plotting moving etc. This is overridden by CompassCatalog since it needs to cast the object to a CompasOnject to apply the CompassFilter. * @param s

Returns:

boolean

Throws:

-
