Class JsonExporter

java.lang.Object

se.itu.systemet.storage.JsonExporter

All Implemented Interfaces:

Product.Exporter

public class JsonExporter
extends Object
implements Product.Exporter

This class is used when we want to export the state of a Product for use in a different context or format.

A JsonExporter object can, produce a String with the Json representing a Product.

Typical usage:

     Product p1 = new Product.Builder()
     .name("Renat")
     .price(209.00)
     .alcohol(37.50)
     .volume(700)
     .nr(101)
     .productGroup("Okryddad sprit")
     .build();

     JsonExporter jsonExp = new JsonExporter();
     p1.export(jsonExp);
     System.out.println(jsonExp.toJsonString());
 

The above will print (on a single line): // note: should we say productGroup or product_group?

{
       "name": "Renat",
       "price": 209.00,
       "alcohol": 37.50,
       "volume": 700,
       "nr": 101,
       "product_group": "Okryddad sprit" 
}
