Interface GlobalContributionOperatorInterface

All Known Implementing Classes:

GlobalContributionOperator

public interface GlobalContributionOperatorInterface

An interface for classes that provide an operator to globally combine the fuzzy values of the output of fuzzy rules. By default the union operator is used, but commonly the sum operator is also used. There may also be other operators added as required.

Method Summary

nrc.fuzzy.FuzzyValue

execute(nrc.fuzzy.FuzzyValue newFuzzyValue, nrc.fuzzy.FuzzyValue existingFuzzyValue) Classes that implement the GlobalContributionOperatorInterface must provide an execute method that accepts 2 fuzzy values and returns a fuzzy value that is the result of doing the operation that the class implements (e.g.

execute

public nrc.fuzzy.FuzzyValue execute(nrc.fuzzy.FuzzyValue newFuzzyValue,
                                    nrc.fuzzy.FuzzyValue existingFuzzyValue)
                             throws IncompatibleFuzzyValuesException,
                                    XValueOutsideUODException

Classes that implement the GlobalContributionOperatorInterface must provide an execute method that accepts 2 fuzzy values and returns a fuzzy value that is the result of doing the operation that the class implements (e.g. union or sum or none).

Parameters:

newFuzzyValue - should be the new FuzzyValue being asserted

existingFuzzyValue - should be the existing FuzzyValue

Returns:

FuzzyValue that is the result of applying the operator to the 2 values
