RdfLiteral.mapper constructor

Creates a reference to a mapper that will be instantiated from the given type.

The generator will create an instance of mapperType to handle literal term mapping for this class. The type must implement LiteralTermMapper<T> where T is the annotated class and it must have a no-argument default constructor.

This approach is useful when the mapper has a default constructor and doesn't require additional configuration parameters.

Example:

@RdfLiteral.mapper(TemperatureMapper)
class Temperature {
  final double celsius;
  Temperature(this.celsius);
  // ...
}

// The mapper implementation must be accessible to the generator:
class TemperatureMapper implements LiteralTermMapper<Temperature> {
  @override
  LiteralTerm toRdfTerm(Temperature temp, SerializationContext context) {
    return LiteralTerm('${temp.celsius}°C');
  }

  @override
  Temperature fromRdfTerm(LiteralTerm term, DeserializationContext context) {
    return Temperature(double.parse(term.value.replaceAll('°C', '')));
  }
}
