Class JColor

java.lang.Object

salvo.jesus.graph.javax.swing.JColor

All Implemented Interfaces:

Serializable

public class JColor
extends Object
implements Serializable

Encapsulates a Color object so that the Color can be changed without changing reference to the JColor object.

This class was created because the Color class has no method to change its existing Color composition, making it difficult to change a color without creating another Color object.

Therefore, programs should make a refernece to a JColor object instead of a Color object, allowing changing of the encapsulated Color object without changing the reference to the JColor object.
