public class ClassPattern
extends java.awt.Rectangle
implements java.lang.Comparable

Represents the class pattern. Class patterns express conditions on filtered subsets of instances of the specific class and are populated with one or more slot patterns.
Class patterns are associated with a class box and have a number of slot patterns, which are stored in a vector. Each slot pattern is stored in a separate line and is identified by the slot name.
Each class pattern is associated with four (4) points that represent:

• the positive incoming connection point
• the negative incoming connection point
• the positive outgoing connection point
• the negative outgoing connection point
