readRange (NotesCalendar - JavaScript™)

Gets a summary of calendar entries for a range of times.

Defined in

Syntax

readRange(start:NotesDateTime, end:NotesDateTime)
: string

readRange(start:NotesDateTime, end:NotesDateTime, skipcount:int, maxread:int) : string


Parameter	Description
`start`	The start time of the range.
`end`	The end time of the range. An exception occurs if the end time is not greater than the start time.
`skipcount`	The number of entries to skip from the beginning of the range. This parameter can be used in conjunction with EntriesProcessed to read the entries in a series of calls.
`maxread`	The maximum number of entries to read.


Return value	Description
`string`	A summary in `iCalendar` format of the entries from the start date to the end date, inclusive. An exception occurs if the range contains no entries.

Usage

For recurring entries, each entry in the range appears as a separate VEVENT with a unique recurrence ID.

Each entry contains a UID item whose value can be used to get the corresponding NotesCalendarEntry object.

Inclusion in a date range is determined by the start time of a meeting.

The content of the return value is modified by any values set for ReadRangeMask1 and ReadRangeMask2.

Use the last two parameters in conjunction with EntriesProcessed to process entries in successive operations. See EntriesProcessed for an example using the last two parameters.

Examples

This button event gets calendar and scheduling information for the current user for today and tomorrow.

// Get calendar for current user
var dbdir:NotesDbDirectory = session.getDbDirectory("");
var maildb:NotesDatabase = dbdir.openMailDatabase();
var cal:NotesCalendar = session.getCalendar(maildb);
var dt1:NotesDateTime = session.createDateTime("Today 08");
var dt2:NotesDateTime = session.createDateTime("Tomorrow 17");
// Read range and set to requestScope variable bound to multiline text box
try {
	requestScope.status = cal.readRange(dt1, dt2);
} catch(e) {
	requestScope.status = "Nothing in that range";
}

This is sample output.
