getTotalRowCount()

ILIAS\AdministrativeNotification\DataRetrieval::getTotalRowCount	(	mixed	$additional_viewcontrol_data,
		mixed	$filter_data,
		mixed	$additional_parameters
	)

Mainly for the purpose of pagination-support, it is important to know about the total number of records available.

Given the nature of a DataTable, which is, opposite to a PresentationTable, rather administrative than explorative, this information will increase user experience quite a bit. However, you may return null, if the call is to costly, but expect the View Control to look a little different in this case.

Make sure that potential filters or user restrictions are being applied to the count.
