    • Method Detail

      • serialize

        public String serialize​(Object value)
        Serialize a DoubleScalar value to text in such a way that it can be deserialized with the corresponding deserializer. In this case, it serializes the class name of the Scalar, followed by a hash sign, followed by the printed value of the scalar including the unit. So a Length of 12.5 kilometer will return "org.djunits.value.vdouble.scalar.Length#12.5 km".
        Specified by:
        serialize in interface TextSerializer<U extends org.djunits.unit.Unit<U>>
        Parameters:
        value - Object; the scalar to serialize
        Returns:
        String; a string representation of the value that can later be deserialized

      • deserialize

        public S deserialize​(String text)
        Deserialize a String to the correct DoubleScalar value in line with the DoubleScalarSerializer.serialize method. In this case, it assumes a string with the class name of the Scalar, followed by a hash sign, followed by the printed value of the scalar including the unit. So, the String "org.djunits.value.vdouble.scalar.Length#12.5 km" will be deserialized into a Length of 12500 m with LengthUnit.KILOMETER as the display unit. The method caches the valueOf(String) method for repeated use.
        Specified by:
        deserialize in interface TextSerializer<U extends org.djunits.unit.Unit<U>>
        Parameters:
        text - String; the text to deserialize
        Returns:
        S; the reconstructed scalar
