/**
* A builder for creating {@link 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.
*
* <p>The class {@link javax.json.Json} contains methods to create the builder
* object. The example code below shows how to build an empty {@code JsonObject}
* instance.
* <pre>
* <code>
* JsonObject object = Json.createObjectBuilder().build();
* </code>
* </pre>
*
* <p>The class {@link JsonBuilderFactory} also contains methods to create
* {@code 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.
*
* <a id="JsonObjectBuilderExample1"/>
* The example code below shows how to build a {@code JsonObject} model that
* represents the following JSON object:
*
* <pre>
* <code>
* {
* "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" }
* ]
* }
* </code>
* </pre>
*
* <p>The code to create the object shown above is the following:
*
* <pre>
* <code>
* 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();
* </code>
* </pre>
*
* <p>This class does <em>not</em> allow <tt>null</tt> to be used as a name or
* value while building the JSON object
*
* @see JsonArrayBuilder
