)Parameters
| Name | Type | Description |
|---|---|---|
| interval | TimeInterval | A TimeInterval object which is the required time interval. |
Optional Parameters
| Name | Type | Default | Description |
|---|---|---|---|
| useCache | Boolean | False | True, to use appointment cache to increase performance. When set to false, enables you to operate with SchedulerStorage in multiple threads, since different requests for appointments will not use the same cache. |
Returns
| Type | Description |
|---|---|
| AppointmentBaseCollection | An AppointmentBaseCollection collection of appointments which belong to the specified time interval. |
Remarks
The GetAppointments method returns appointments of any type (regular appointments, recurring appointments and exceptions) that belong to the specified time interval. If an appointment’s time interval partially overlaps the specified interval, this appointment is also included in the collection returned.
The GetAppointments method gets appointments contained in the storage and passed through filters. Appointment filters are the AppointmentStorageBase.Filter property and the SchedulerStorageBase.FilterAppointment event.
By default, SchedulerControl creates a cache of the recently used appointments to increase performance. If you operate with recurrent appointments, occurrences for a certain pattern are generated only once and then cached to allow accessing them faster.
