Class SimpleRule

java.lang.Object
  org.opensubsystems.patterns.listdata.data.SimpleRule

All Implemented Interfaces:

java.io.Serializable

public class SimpleRule
extends java.lang.Object
implements java.io.Serializable

This class represents set of data conditions which are connected with logical operation and can be used to filter or match data object. Since only single operator such as AND or OR is used to connect all data condition it is considered to be a simple rule (as oposed to complex rule where these operations could be mixed).
