    • Method Detail

      • intValue

        public int intValue()
        Description copied from interface: ObservableNumberValue
        Returns the value of this ObservableNumberValue as an int . If the value is not an int, a standard cast is performed.
        Specified by:
        intValue in interface ObservableNumberValue
        Returns:
        The value of this ObservableNumberValue as an int
      • longValue

        public long longValue()
        Description copied from interface: ObservableNumberValue
        Returns the value of this ObservableNumberValue as a long . If the value is not a long, a standard cast is performed.
        Specified by:
        longValue in interface ObservableNumberValue
        Returns:
        The value of this ObservableNumberValue as a long
      • floatValue

        public float floatValue()
        Description copied from interface: ObservableNumberValue
        Returns the value of this ObservableNumberValue as a float. If the value is not a float, a standard cast is performed.
        Specified by:
        floatValue in interface ObservableNumberValue
        Returns:
        The value of this ObservableNumberValue as a float
      • doubleValue

        public double doubleValue()
        Description copied from interface: ObservableNumberValue
        Returns the value of this ObservableNumberValue as a double. If the value is not a double, a standard cast is performed.
        Specified by:
        doubleValue in interface ObservableNumberValue
        Returns:
        The value of this ObservableNumberValue as a double
      • floatExpression

        public static FloatExpression floatExpression​(ObservableFloatValue value)
        Returns a FloatExpression that wraps a ObservableFloatValue. If the ObservableFloatValue is already a FloatExpression, it will be returned. Otherwise a new FloatBinding is created that is bound to the ObservableFloatValue.
        Parameters:
        value - The source ObservableFloatValue
        Returns:
        A FloatExpression that wraps the ObservableFloatValue if necessary
        Throws:
        NullPointerException - if value is null
      • floatExpression

        public static <T extends NumberFloatExpression floatExpression​(ObservableValue<T> value)
        Returns a FloatExpression that wraps an ObservableValue. If the ObservableValue is already a FloatExpression, it will be returned. Otherwise a new FloatBinding is created that is bound to the ObservableValue.

        Note: this method can be used to convert an ObjectExpression or ObjectProperty of specific number type to FloatExpression, which is essentially an ObservableValue<Number>. See sample below.

           FloatProperty floatProperty = new SimpleFloatProperty(1.0f);
           ObjectProperty<Float> objectProperty = new SimpleObjectProperty<>(2.0f);
           BooleanBinding binding = floatProperty.greaterThan(FloatExpression.floatExpression(objectProperty));
         
        Note: null values will be interpreted as 0f
        Type Parameters:
        T - The type of Number to be wrapped
        Parameters:
        value - The source ObservableValue
        Returns:
        A FloatExpression that wraps the ObservableValue if necessary
        Throws:
        NullPointerException - if value is null
