Interface JsonArrayBuilder

public interface JsonArrayBuilder

A builder for creating JsonArray models from scratch. This interface initializes an empty JSON array model and provides methods to add values to the array model and to return the resulting array. The methods in this class can be chained to add multiple values to the array.

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

 
 JsonArray array = Json.createArrayBuilder().build();
 
 

The class JsonBuilderFactory also contains methods to create JsonArrayBuilder 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 JsonArray object that represents the following JSON array:

 
 [
     { "type": "home", "number": "212 555-1234" },
     { "type": "fax", "number": "646 555-4567" }
 ]
 
 

The following code creates the JSON array above:

 
 JsonBuilderFactory factory = Json.createBuilderFactory(config);
 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();
 
 

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