getNotes(notes: NotificationArray input;
transients: Boolean;
maxEntries: Integer);
The getNotes method of the System class populates the array specified in the notes parameter with transient instances of the current notification requests by all the processes in the system.
The parameters of the getNotes method are listed in the following table.
| Parameter | Specifies… |
|---|---|
| notes | The notifications array that is to be populated with the notification instances. |
| transients | Whether the notifications to be reported correspond to target transient objects corresponding to this node (true) or to target persistent objects corresponding to all the nodes in the system (false). |
| maxEntries | The maximum number of notification instances to include in the array. |
As this method creates transient instances of the Notification class, it is the responsibility of the method caller to purge the collection used by the method to delete these transient instances. The collection should be purged before the deletion of the notification array passed to the method in the notes parameter.
The following examples show the use of the getNotes method.
vars
note : Notification;
notificationArray : NotificationArray;
begin
create notificationArray transient;
system.getNotes(notificationArray, true, 100);
foreach note in notificationArray do
//access the notification entry properties
write note.target.String;
// now check subscriber class is valid for the user
if app.isValidObject(note.subscriber) then
write note.subscriber.String;
endif;
endforeach;
epilog
notificationArray.purge;
delete notificationArray;
end;
vars
notificationArray : NotificationArray;
begin
create notificationArray transient;
system.getNotes(notificationArray, true, 32000);
write notificationArray.size.String & ' transient notifications';
notificationArray.clear;
system.getNotes(notificationArray, false, 32000);
write notificationArray.size.String & ' persistent notifications';
epilog
notificationArray.purge;
delete notificationArray;
end;
