Interface JsonObjectBuilder

public interface JsonObjectBuilder
A builder for creating JsonObject models from scratch. This interface initializes an empty JSON object model and provides methods to add name/value pairs to the object model and to return the resulting object. The methods in this class can be chained to add multiple name/value pairs to the object.

The class Json contains methods to create the builder object. The example code below shows how to build an empty JsonObject instance. 

 
 JsonObject object = Json.createObjectBuilder().build();

The class JsonBuilderFactory also contains methods to create JsonObjectBuilder instances. A factory instance can be used to create multiple builder instances with the same configuration. This the preferred way to create multiple instances. The example code below shows how to build a JsonObject model that represents the following JSON object: 

 
 {
     "firstName": "John", "lastName": "Smith", "age": 25,
     "address" : {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": "10021"
     },
     "phoneNumber": [
         { "type": "home", "number": "212 555-1234" },
         { "type": "fax", "number": "646 555-4567" }
     ]
 }

The code to create the object shown above is the following: 

 
 JsonBuilderFactory factory = Json.createBuilderFactory(config);
 JsonObject value = factory.createObjectBuilder()
     .add("firstName", "John")
     .add("lastName", "Smith")
     .add("age", 25)
     .add("address", factory.createObjectBuilder()
         .add("streetAddress", "21 2nd Street")
         .add("city", "New York")
         .add("state", "NY")
         .add("postalCode", "10021"))
     .add("phoneNumber", factory.createArrayBuilder()
         .add(factory.createObjectBuilder()
             .add("type", "home")
             .add("number", "212 555-1234"))
         .add(factory.createObjectBuilder()
             .add("type", "fax")
             .add("number", "646 555-4567")))
     .build();

This class does not allow null to be used as a name or value while building the JSON object
