All Implemented Interfaces:

Comparator, Serializable

public class ContourCell

extends Object

implements Comparator, Serializable

Data structure internal to JClass Chart 3D. Stores contour information on a per cell basis.

Serialized Form

Field Summary

protected ArrayList[]	corners A contour intersection list for each corner of the cell.
protected boolean	hole Does this cell correspond to a hole?
protected com.klg.jclass.chart3d.Intersection	newIntersection A place to temporarily store new Intersections.
protected int	nIntersections The number of contour intersections for this cell.
protected ArrayList	side A contour intersection list for the side of the cell (either vertical or horizontal, it can't be both).
static int	SIDE

Method Summary

protected void	addIntersection(com.klg.jclass.chart3d.Intersection intersection, int place) Adds an intersection to one of the four corner lists or the side list.
int	compare(Object o1, Object o2) Generic segment sorting routine, for all four corners, and sides (left-to-right or top-to-bottom).
ArrayList	getIntersectionList(int place)
protected com.klg.jclass.chart3d.Intersection	getNewIntersection() Gets the newest intersection (possibly still under construction).
int	getNIntersections() Retrieves the number of contour intersections for this cell.
protected boolean	isHole() Does this cell correspond to a hole?
protected void	setHole(boolean hole) Sets whether this cell corresponds to a hole or not.
protected void	setNewIntersection(com.klg.jclass.chart3d.Intersection newIntersection) Sets the newest intersection.
protected void	sortIntersectionLists() Sorts the contour intersection lists of each of the four corners and the side list.

Constant Field Values

hole

protected boolean hole

Does this cell correspond to a hole?

nIntersections

protected int nIntersections

The number of contour intersections for this cell.

corners

protected ArrayList[] corners

A contour intersection list for each corner of the cell.

side

protected ArrayList side

A contour intersection list for the side of the cell (either vertical or horizontal, it can't be both).

newIntersection

protected com.klg.jclass.chart3d.Intersection newIntersection

A place to temporarily store new Intersections.

Method Detail

setHole

protected void setHole(boolean hole)

Sets whether this cell corresponds to a hole or not.

Parameters:

hole -

isHole

protected boolean isHole()

Does this cell correspond to a hole?

addIntersection

protected void addIntersection(com.klg.jclass.chart3d.Intersection intersection,
                               int place)

Adds an intersection to one of the four corner lists or the side list.

Parameters:

intersection -

place -

getNIntersections

public int getNIntersections()

Retrieves the number of contour intersections for this cell.

getNewIntersection

protected com.klg.jclass.chart3d.Intersection getNewIntersection()

Gets the newest intersection (possibly still under construction).

setNewIntersection

protected void setNewIntersection(com.klg.jclass.chart3d.Intersection newIntersection)

Sets the newest intersection.

Parameters:

newIntersection -

getIntersectionList

public ArrayList getIntersectionList(int place)

Parameters:

place -

sortIntersectionLists

protected void sortIntersectionLists()

Sorts the contour intersection lists of each of the four corners and the side list.

compare

public int compare(Object o1,
                   Object o2)

Generic segment sorting routine, for all four corners, and sides (left-to-right or top-to-bottom). Each of these has a list of intersections that need to be sorted. We know that all edges have the same side1 and side2, so the sorting is easy.

Specified by:

compare in interface Comparator

Parameters:

o1 -

o2 -
