/**
* A builder for creating {@link 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.
*
* <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 JsonArray}
* instance.
* <pre>
* <code>
* JsonArray array = Json.createArrayBuilder().build();
* </code>
* </pre>
*
* <p>The class {@link JsonBuilderFactory} also contains methods to create
* {@code 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.
*
* <a id="JsonArrayBuilderExample1"/>
* The example code below shows how to build a {@code JsonArray} object
* that represents the following JSON array:
*
* <pre>
* <code>
* [
* { "type": "home", "number": "212 555-1234" },
* { "type": "fax", "number": "646 555-4567" }
* ]
* </code>
* </pre>
*
* <p>The following code creates the JSON array above:
*
* <pre>
* <code>
* 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();
* </code>
* </pre>
*
* <p>This class does <em>not</em> allow <tt>null</tt> to be used as a
* value while building the JSON array
*
