41/**
42 * <p>
43 * The contract between the calendar provider and applications. Contains
44 * definitions for the supported URIs and data columns.
45 * </p>
46 * <h3>Overview</h3>
47 * <p>
48 * CalendarContract defines the data model of calendar and event related
49 * information. This data is stored in a number of tables:
50 * </p>
51 * <ul>
52 * <li>The {@link Calendars} table holds the calendar specific information. Each
53 * row in this table contains the details for a single calendar, such as the
54 * name, color, sync info, etc.</li>
55 * <li>The {@link Events} table holds the event specific information. Each row
56 * in this table has the info for a single event. It contains information such
57 * as event title, location, start time, end time, etc. The event can occur
58 * one-time or can recur multiple times. Attendees, reminders, and extended
59 * properties are stored on separate tables and reference the {@link Events#_ID}
60 * to link them with the event.</li>
61 * <li>The {@link Instances} table holds the start and end time for occurrences
62 * of an event. Each row in this table represents a single occurrence. For
63 * one-time events there will be a 1:1 mapping of instances to events. For
64 * recurring events, multiple rows will automatically be generated which
65 * correspond to multiple occurrences of that event.</li>
66 * <li>The {@link Attendees} table holds the event attendee or guest
67 * information. Each row represents a single guest of an event. It specifies the
68 * type of guest they are and their attendance response for the event.</li>
69 * <li>The {@link Reminders} table holds the alert/notification data. Each row
70 * represents a single alert for an event. An event can have multiple reminders.
71 * The number of reminders per event is specified in
72 * {@link Calendars#MAX_REMINDERS} which is set by the Sync Adapter that owns
73 * the given calendar. Reminders are specified in minutes before the event and
74 * have a type.</li>
75 * <li>The {@link ExtendedProperties} table holds opaque data fields used by the
76 * sync adapter. The provider takes no action with items in this table except to
77 * delete them when their related events are deleted.</li>
78 * </ul>
79 * <p>
80 * Other tables include:
81 * </p>
82 * <ul>
83 * <li>
84 * {@link SyncState}, which contains free-form data maintained by the sync
85 * adapters</li>
86 * </ul>

545     * either as an app or as a sync adapter. To perform an operation as a sync
546     * adapter {@link #CALLER_IS_SYNCADAPTER} should be set to true and
547     * {@link #ACCOUNT_NAME} and {@link #ACCOUNT_TYPE} must be set in the Uri
548     * parameters. See
549     * {@link Uri.Builder#appendQueryParameter(java.lang.String, java.lang.String)}
550     * for details on adding parameters. Sync adapters have write access to more
551     * columns but are restricted to a single account at a time. Calendars are
552     * designed to be primarily managed by a sync adapter and inserting new
553     * calendars should be done as a sync adapter. For the most part, apps
554     * should only update calendars (such as changing the color or display
555     * name). If a local calendar is required an app can do so by inserting as a
556     * sync adapter and using an {@link #ACCOUNT_TYPE} of
557     * {@link #ACCOUNT_TYPE_LOCAL} .
558     * <dl>
559     * <dt><b>Insert</b></dt>

569     * </ul>
570     * The following fields are not required when inserting a Calendar but are

572     * <ul>
573     * <li>{@link #SYNC_EVENTS} set to 1</li>
574     * <li>{@link #CALENDAR_TIME_ZONE}</li>

577     * <dt><b>Update</b></dt>
578     * <dd>To perform an update on a calendar the {@link #_ID} of the calendar
579     * should be provided either as an appended id to the Uri (
580     * {@link ContentUris#withAppendedId}) or as the first selection item--the
581     * selection should start with "_id=?" and the first selectionArg should be
582     * the _id of the calendar. Calendars may also be updated using a selection
583     * without the id. In general, the {@link #ACCOUNT_NAME} and
584     * {@link #ACCOUNT_TYPE} should not be changed after a calendar is created
585     * as this can cause issues for sync adapters.
586     * <dt><b>Delete</b></dt>
587     * <dd>Calendars can be deleted either by the {@link #_ID} as an appended id
588     * on the Uri or using any standard selection. Deleting a calendar should
589     * generally be handled by a sync adapter as it will remove the calendar
590     * from the database and all associated data (aka events).</dd>
591     * <dt><b>Query</b></dt>
592     * <dd>Querying the Calendars table will get you all information about a set
593     * of calendars. There will be one row returned for each calendar that

1404     * Constants and helpers for the Events table, which contains details for
1405     * individual events. <h3>Operations</h3> All operations can be done either
1406     * as an app or as a sync adapter. To perform an operation as a sync adapter
1407     * {@link #CALLER_IS_SYNCADAPTER} should be set to true and
1408     * {@link #ACCOUNT_NAME} and {@link #ACCOUNT_TYPE} must be set in the Uri
1409     * parameters. See
1410     * {@link Uri.Builder#appendQueryParameter(java.lang.String, java.lang.String)}
1411     * for details on adding parameters. Sync adapters have write access to more
1412     * columns but are restricted to a single account at a time.
1413     * <dl>
1414     * <dt><b>Insert</b></dt>
1415     * <dd>When inserting a new event the following fields must be included:
1416     * <ul>
1417     * <li>dtstart</li>
1418     * <li>dtend if the event is non-recurring</li>
1419     * <li>duration if the event is recurring</li>
1420     * <li>rrule or rdate if the event is recurring</li>
1421     * <li>a calendar_id</li>
1422     * </ul>
1423     * There are also further requirements when inserting or updating an event.
1424     * See the section on Writing to Events.</dd>
1425     * <dt><b>Update</b></dt>
1426     * <dd>To perform an update of an Event the {@link Events#_ID} of the event
1427     * should be provided either as an appended id to the Uri (
1428     * {@link ContentUris#withAppendedId}) or as the first selection item--the
1429     * selection should start with "_id=?" and the first selectionArg should be
1430     * the _id of the event. Updates may also be done using a selection and no
1431     * id. Updating an event must respect the same rules as inserting and is
1432     * further restricted in the fields that can be written. See the section on
1433     * Writing to Events.</dd>
1434     * <dt><b>Delete</b></dt>
1435     * <dd>Events can be deleted either by the {@link Events#_ID} as an appended
1436     * id on the Uri or using any standard selection. If an appended id is used
1437     * a selection is not allowed. There are two versions of delete: as an app
1438     * and as a sync adapter. An app delete will set the deleted column on an
1439     * event and remove all instances of that event. A sync adapter delete will
1440     * remove the event from the database and all associated data.</dd>
1441     * <dt><b>Query</b></dt>
1442     * <dd>Querying the Events table will get you all information about a set of
1443     * events except their reminders, attendees, and extended properties. There
1444     * will be one row returned for each event that matches the query selection,
1445     * or at most a single row if the {@link Events#_ID} is appended to the Uri.
1446     * Recurring events will only return a single row regardless of the number
1447     * of times that event repeats.</dd>
1448     * </dl>
1449     * <h3>Writing to Events</h3> There are further restrictions on all Updates
1450     * and Inserts in the Events table:
1451     * <ul>
1452     * <li>If allDay is set to 1 eventTimezone must be {@link Time#TIMEZONE_UTC}
1453     * and the time must correspond to a midnight boundary.</li>
1454     * <li>Exceptions are not allowed to recur. If rrule or rdate is not empty,
1455     * original_id and original_sync_id must be empty.</li>
1456     * <li>In general a calendar_id should not be modified after insertion. This
1457     * is not explicitly forbidden but many sync adapters will not behave in an
1458     * expected way if the calendar_id is modified.</li>
