static ilDiskQuotaChecker::__updateDiskUsageReportOfType (   $a_access_obj,

staticprivate

Updates the disk usage report of the specified object type for all user accounts.

The results are stored in table usr_pref. For each user which owns files the following rows are inserted:

Parameters
$a_access_objObject A access object, such as ilObjFileAccess.
$a_typestring The type of the access object, such as 'file'.

Keyword Value Description 'disk_usage.file.count' integer The number of files owned by the user 'disk_usage.file.usage' integer The disk usage of the files
