46/**
47 * A builder for creating {@link JsonObject} models from scratch. This
48 * interface initializes an empty JSON object model and provides methods to add
49 * name/value pairs to the object model and to return the resulting object.
50 * The methods in this class can be chained to add multiple name/value pairs
51 * to the object.
52 *
53 * <p>The class {@link javax.json.Json} contains methods to create the builder
54 * object. The example code below shows how to build an empty {@code JsonObject}
55 * instance.
56 * <pre>
57 * <code>
58 * JsonObject object = Json.createObjectBuilder().build();
59 * </code>
60 * </pre>
61 *
62 * <p>The class {@link JsonBuilderFactory} also contains methods to create
63 * {@code JsonObjectBuilder} instances. A factory instance can be used to create
64 * multiple builder instances with the same configuration. This the preferred
65 * way to create multiple instances.
66 *
67 * <a id="JsonObjectBuilderExample1"/>
68 * The example code below shows how to build a {@code JsonObject} model that
69 * represents the following JSON object:
70 *
71 * <pre>
72 * <code>
73 * {
74 * "firstName": "John", "lastName": "Smith", "age": 25,
75 * "address" : {
76 * "streetAddress": "21 2nd Street",
77 * "city": "New York",
78 * "state": "NY",
79 * "postalCode": "10021"
80 * },
81 * "phoneNumber": [
82 * { "type": "home", "number": "212 555-1234" },
83 * { "type": "fax", "number": "646 555-4567" }
84 * ]
85 * }
86 * </code>
87 * </pre>
88 *
89 * <p>The code to create the object shown above is the following:
90 *
91 * <pre>
92 * <code>
93 * JsonBuilderFactory factory = Json.createBuilderFactory(config);
94 * JsonObject value = factory.createObjectBuilder()
95 * .add("firstName", "John")
96 * .add("lastName", "Smith")
97 * .add("age", 25)
98 * .add("address", factory.createObjectBuilder()
99 * .add("streetAddress", "21 2nd Street")
100 * .add("city", "New York")
101 * .add("state", "NY")
102 * .add("postalCode", "10021"))
103 * .add("phoneNumber", factory.createArrayBuilder()
104 * .add(factory.createObjectBuilder()
105 * .add("type", "home")
106 * .add("number", "212 555-1234"))
107 * .add(factory.createObjectBuilder()
108 * .add("type", "fax")
109 * .add("number", "646 555-4567")))
110 * .build();
111 * </code>
112 * </pre>
113 *
114 * <p>This class does <em>not</em> allow <tt>null</tt> to be used as a name or
115 * value while building the JSON object
