    • Method Detail

      • numberExpression

        public static <S extends NumberNumberExpressionBase numberExpression​(ObservableNumberValue value)
        Returns an NumberExpressionBase that wraps a ObservableNumberValue. If the ObservableNumberValue is already an instance of NumberExpressionBase, it will be returned. Otherwise a new NumberBinding is created that is bound to the ObservableNumberValue.
        Type Parameters:
        S - The type of Number to be wrapped
        Parameters:
        value - The source ObservableNumberValue
        Returns:
        An NumberExpressionBase that wraps the ObservableNumberValue if necessary
        Throws:
        NullPointerException - if value is null
      • isEqualTo

        public BooleanBinding isEqualTo​(ObservableNumberValue other,
                                        double epsilon)
        Description copied from interface: NumberExpression
        Creates a new BooleanBinding that holds true if this and another ObservableNumberValue are equal (with a tolerance).

        Two operands a and b are considered equal if Math.abs(a-b) <= epsilon.

        Allowing a small tolerance is recommended when comparing floating-point numbers because of rounding-errors.

        Specified by:
        isEqualTo in interface NumberExpression
        Parameters:
        other - the second ObservableNumberValue
        epsilon - the tolerance
