class HDiskCatalog: public TNamed

 compare function for sorting dirs alphabetically by
 owner name

 compare function for sorting dirs by size descending

 compare function for sorting dirs by number of files descending

 compare function for sorting dirs by number of small files descending

 compare function for sorting dirs by number of small files descending

 returns HDiskDir* p from index by name.
 pointer is NULL if not found

 returns HDiskDir* p from index by name.
 pointer is NULL if not found

 prints all dirs (up to maxlevel, default is all)

 fill all dir names of directory to vector.
 uses readdir()

 fill all dir names of directory rekursively to vector.
 uses readdir()

 scans the disk and rescans dirs
 which have been modified since last scan

 set indices of daughter dirs
 does not change nFilesTotal etc.

 use this to produce super catalogs (new empty base,
 than add dirs, last call updateDirIndices())

 get all daughters of dir by index

 get all daughters of dir rekursively by index

 sort daughters of dir by option
 option: name        (name of owner)
         size        (size of directory)
         nfiles      (number of files in directory (rekursively))
         nsmallfiles (number of small files in directory(rekursively))
         filesratio  (number of small files in directory / number of total files)

 sort daughters of dir rekursively by option
 option: name        (name of owner)
         size        (size of directory)
         nfiles      (number of files in directory (rekursively))
         nsmallfiles (number of small files in directory(rekursively))
         filesratio  (number of small files in directory / number of total files)

 prints the catalog of the disk
 maxlevel : number of subdir levels to be shown
 sort option: name        (name of owner)
              size        (size of directory)
              nfiles      (number of files in directory (rekursively))
              nsmallfiles (number of small files in directory(rekursively))
              filesratio  (number of small files / number of total files (rekursively))
 nfill      :  number of character to be inserted in front for each level of subdirs
 filler     :  character to be inserted in front for each level of subdirs

 prints the execution start and stop time and the duration

 filters all dirs fitting the regular expression regexp
 TRegexp is used, read about the limitations
 dirs cand be filtered by last modification range1 to range2
 (format yyyy-mm-dd hh:mm:ss). default is no filter

 the path and regexpfile for the file name

 lookup of user uid in the map of
 known users. if the user can not be
 found the the user name will be unknown_uid

 lookup of group gid in the map of
 known groups. if the group can not be
 found the the group name will be unknown_gid
