All Implemented Interfaces:

java.lang.Cloneable, GlobalContributionOperatorInterface, java.io.Serializable

public class UnionGlobalContributionOperator

extends GlobalContributionOperator

implements java.io.Serializable

A class that provides a 'union' operator to combine fuzzy values when doing global contribution. For example, when a temperature fuzzy value is asserted by more than 1 rule, the existing fuzzy value and the new fuzzy value are combined to form a new fuzzy value that represents the desired way to combine both pieces of information. This will normally be the union of the 2 fuzzy values but can be set to other operations such as the summ of the fuzzy values (or it can also be set to perform no global combining and just replace the exiting value with the new one).

                                    XValueOutsideUODException

Class that implements the Union operator via an execute method that accepts 2 fuzzy values and returns a fuzzy value that is the result of doing the fuzzy union.

Specified by:

execute in interface GlobalContributionOperatorInterface

Parameters:

newFuzzyValue - should be the new FuzzyValue being asserted

existingFuzzyValue - should be the existing FuzzyValue

Returns:

FuzzyValue that is the result of doing a fuzzy union of the 2 values
