| * Denotes that the annotated element of integer type, represents |

| * multiple constants can be combined. |

| * Example: |
| * <pre><code> |
| * @Retention(SOURCE) |
| * @IntDef({NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS}) |
| * public @interface NavigationMode {} |
| * public static final int NAVIGATION_MODE_STANDARD = 0; |
| * public static final int NAVIGATION_MODE_LIST = 1; |
| * public static final int NAVIGATION_MODE_TABS = 2; |
| * ... |
| * public abstract void setNavigationMode(@NavigationMode int mode); |
| * @NavigationMode |
| * public abstract int getNavigationMode(); |
| * </code></pre> |
| * For a flag, set the flag attribute: |
| * <pre><code> |
| * @IntDef( |
| * flag = true, |
| * value = {NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS}) |
| * </code></pre> |
