Class PointArrayTable

  mr3d.debug.ErrorHandling
      mr3d.PointArrayTable

All Implemented Interfaces:

Debugable

public class PointArrayTable

extends ErrorHandling

implements Debugable

The point array table manages the 3D-points of a 3D-scene. It is a collection of 3D-points. It also is an administrative object that ensures that 3D-points are only stored once and it gives all classes an interface to access the points.

PointArrayTable is a Singleton.

Field Detail

instance

private static PointArrayTable instance

Reference to the only instance of the class.

nrOfInstances

private static int nrOfInstances

Stores the number of instances of ObjectArray. This is neccessary to make sure there is only one instance.

points

private java.util.Vector points

vector containing all 3D-points of the scene

Constructor Detail

PointArrayTable

private PointArrayTable()

Creates a new PointArrayTable. The constructor is private for PointArrayTable is a Singleton.

Method Detail

addPoint

public void addPoint(Point3D newPoint)

Adds a 3D-point to the point vector.

Parameters:

newPoint - point to be added

clearPoints

public void clearPoints()

Clears out the point array table. This is needed when a new scene should be loaded.

createInstance

public static PointArrayTable createInstance()

Creates one instance of the PointArrayTable. This method checks the nrOfInstances value to ensure only one instance is running. If nrOfIntances is greater then 0 the instance referenced in instance is returned.

Returns:

an instance of PointArrayTable

getPoint

public Point3D getPoint(int index)

Returns the 3D-point at the specified index

Parameters:

index - point array index of the point

size

public int size()

Returns the number of points in the point array table.

toConsole

public void toConsole()

Description copied from interface: Debugable

Prints the contents of the object to the Java console. How the information will be displayed depends on what data the object contains. Depending on structure and contents every implementation of this function produces a different result on the console.

Description copied from interface: Debugable

Prints the contents of the object to the Java console together with an information string. How the information will be displayed depends on what data the object contains. Depending on structure and contents every implementation of this function produces a different result on the console.
