fromJSON method

FuzzyRule fromJSON(Map<String, dynamic> json, Map<String, FuzzySet> fuzzySets)

Restores this instance from the given JSON object.

Implementation

FuzzyRule fromJSON(Map<String,dynamic> json, Map<String,FuzzySet> fuzzySets ) {

	parseTerm( termJSON ) {

			// atomic term -> FuzzySet
			final uuid = termJSON;
			return fuzzySets[uuid];
		}
      else {
			// composite term
			final type = termJSON['type'];

			dynamic term;

			switch ( type ) {

					term = FuzzyAND();
					break;
				case 'FuzzyOR':
					term = FuzzyOR();
					break;
				case 'FuzzyVERY':
					term = FuzzyVERY();
					break;
				case 'FuzzyFAIRLY':
					term = FuzzyFAIRLY();
					break;
				default:
					yukaConsole.error( 'YUKA.FuzzyRule: Unsupported operator type: $type' );
					return;
			}

			final termsJSON = termJSON.terms;

			for ( int i = 0, l = termsJSON.length; i < l; i ++ ) {
				// recursively parse all subordinate terms
				term.terms.add( parseTerm( termsJSON[ i ] ) );
			}

			return term;
