  • Method Details

    • evaluateRule

      public void evaluateRule(String rule) throws RuleParsingException
      Evaluates a single rule provided as a string. The rule string is parsed, executed, and the results affect the associated linguistic variables.
      Parameters:
      rule - the string representation of the fuzzy rule
      Throws:
      RuleParsingException - if the rule syntax is invalid

    • evaluateRule

      public void evaluateRule(FuzzyRule rule)
      Evaluates a pre-parsed FuzzyRule object.
      Parameters:
      rule - the fuzzy rule to evaluate

    • evaluateRules

    • addRule

      public FuzzyRule addRule(String rule) throws RuleParsingException
      Parses and registers a new rule from its string representation.
      Parameters:
      rule - the rule string
      Returns:
      the created FuzzyRule object
      Throws:
      RuleParsingException - if the rule format is incorrect

    • addRule

      public FuzzyRule addRule(FuzzyRule rule)
      Registers an existing FuzzyRule object with the engine.
      Parameters:
      rule - the rule to add

    • addLinguisticVariable

      public void addLinguisticVariable(LinguisticVariable lv)
      Registers a Linguistic Variable (LV) with the engine. LVs represent concepts like "Temperature" or "Speed" with associated fuzzy sets.
      Parameters:
      lv - the linguistic variable to add

    • getLinguisticVariable

      public LinguisticVariable getLinguisticVariable(String lv)
      Retrieves a registered Linguistic Variable by its name.
      Parameters:
      lv - the name of the variable (e.g., "Pressure")
      Returns:
      the variable object, or null if not found

    • getNumRules
