Interface JsonBuilderFactory

public interface JsonBuilderFactory
Factory to create JsonObjectBuilder and JsonArrayBuilder instances. If a factory instance is configured with some configuration, that would be used to configure the created builder instances.

JsonObjectBuilder and JsonArrayBuilder can also be created using Json's methods. If multiple builder instances are created, then creating them using a builder factory is preferred.

For example: 

 
 JsonBuilderFactory factory = Json.createBuilderFactory(...);
 JsonArray value = 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();
