The static methods of this class calls the same methods of the 40 * service utility. However, the signatures are different because it is difficult 41 * for JSON to support certain types. 42 * </p> 43 * 44 * <p> 45 * ServiceBuilder follows certain rules in translating the methods. For example, 46 * if the method in the service utility returns a <code>java.util.List</code>, that 47 * is translated to a <code>org.json.JSONArray</code>. If the method in the service 48 * utility returns a <code>com.liferay.portlet.shopping.model.ShoppingItem</code>, 49 * that is translated to a <code>org.json.JSONObject</code>. Methods that JSON cannot 50 * safely use are skipped. The logic for the translation is encapsulated in <code>com.liferay.portlet.shopping.service.http.ShoppingItemJSONSerializer</code>. 51 * </p> 52 * 53 * <p> 54 * This allows you to call the the backend services directly from JavaScript. See 55 * <code>portal-web/docroot/html/portlet/tags_admin/unpacked.js</code> for a reference 56 * of how that portlet uses the generated JavaScript in <code>portal-web/docroot/html/js/service.js</code> 57 * to call the backend services directly from JavaScript. 58 * </p> 59 * 60 * <p> 61 * The JSON utility is only generated for remote services. 62 * </p> 63 * 64 * @author Brian Wing Shun Chan 65 * 66 * @see com.liferay.portlet.shopping.service.ShoppingItemServiceUtil 67 * @see com.liferay.portlet.shopping.service.http.ShoppingItemJSONSerializer 68 * 69 */ 70 public class ShoppingItemServiceJSON { 71 public static void addBookItems(long categoryId, java.lang.String[] isbns) 72 throws com.liferay.portal.SystemException, 73 com.liferay.portal.PortalException, java.rmi.RemoteException { 74 ShoppingItemServiceUtil.addBookItems(categoryId, isbns); 75 } 76 77 public static void deleteItem(long itemId) 78 throws com.liferay.portal.SystemException, 79 com.liferay.portal.PortalException, java.rmi.RemoteException { 80 ShoppingItemServiceUtil.deleteItem(itemId); 81 } 82 83 public static JSONObject getItem(long itemId) 84 throws com.liferay.portal.SystemException, 85 com.liferay.portal.PortalException, java.rmi.RemoteException { 86 com.liferay.portlet.shopping.model.ShoppingItem returnValue = ShoppingItemServiceUtil.getItem(itemId); 87 88 return ShoppingItemJSONSerializer.toJSONObject(returnValue); 89 } 90 }
