/**
 * A builder for creating {@link JsonArray} models from scratch, and for
 * modifying a existing {@code JsonArray}.
 * <p>A {@code JsonArrayBuilder} can start with an empty or a non-empty
 * JSON array model. This interface provides methods to add, insert, remove
 * and replace values in the JSON array model.</p>
 * <p>Methods in this class can be chained to perform multiple values to
 * the array.</p>
 *
 * <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.
 *
 * 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 <code>null</code> to be used as a
 * value while building the JSON array
 *
