Class Pattern

java.lang.Object
  |
  +--jess.Pattern
All Implemented Interfaces:
jess.Groupable, java.io.Serializable

public class Pattern
extends java.lang.Object
implements jess.Groupable, java.io.Serializable

Pattern represents a single conditional element on a rule LHS. A Pattern consists mainly of a two-dimensional array of Test1 structures. Each Test1 contains information about a specific characteristic of a slot.
