All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class PaintMap
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable

A storage structure that maps Comparable instances with Paint instances.

To support cloning and serialization, you should only use keys that are cloneable and serializable. Special handling for the Paint instances is included in this class.

Since:

1.0.3
