class TFileInfo: public TNamed

 Constructor.

 Copy constructor.

 Destructor.

 Parse the input line to extract init information from 'in'; the input
 string is tokenized on ' '; the tokens can be prefixed by the following
 keys:

   url:<url1>,<url2>,...     URLs for the file; stored in the order given
   sz:<size>                 size of the file in bytes
   md5:<md5_ascii>           MD5 sum of the file in ASCII form
   uuid:<uuid>               UUID of the file

   tree:<name>,<entries>,<first>,<last>
                             meta-information about a tree in the file; the
                             should be in the form <subdir>/tree-name;'entries' is
                             the number of entries in the tree; 'first' and 'last'
                             define the entry range.

   obj:<name>,<class>,<entries>
                             meta-information about a generic object in the file;
                             the should be in the form <subdir>/obj-name; 'class'
                             is the object class; 'entries' is the number of occurences
                             for this object.

   idx:<index>               Index of this file if sorting with index

 Multiple occurences of 'tree:' or 'obj:' can be specified.
 The initializations done via the input string are superseeded by the ones by other
 parameters in the constructor, if any.
 If no key is given, the token is interpreted as URL(s).

 Set the UUID to the value associated to the string 'uuid'. This is
 useful to set the UUID to the one of the ROOT file during verification.
 NB: we do not change the name in here, because this would screw up lists
     of these objects hashed on the name. Those lists need to be rebuild.
     TFileCollection does that in RemoveDuplicates.

 Return the current url.

 Iterator function, start iteration by calling ResetUrl().
 The first call to NextUrl() will return the 1st element,
 the seconde the 2nd element etc. Returns 0 in case no more urls.

 Find an element from a URL. Returns 0 if not found.

 Add a new URL. If 'infront' is TRUE the new url is pushed at the beginning
 of the list; otherwise is pushed back.
 Returns kTRUE if successful, kFALSE otherwise.

 Remove an URL. Returns kTRUE if successful, kFALSE otherwise.

 Remove URL at given position. Returns kTRUE on success, kFALSE on error.

 Set 'url' as current URL, if in the list
 Return kFALSE if not in the list

 Set 'url' as current URL, if in the list
 Return kFALSE if not in the list

 Add's a meta data object to the file info object. The object will be
 adopted by the TFileInfo and should not be deleted by the user.
 Typically objects of class TFileInfoMeta or derivatives should be added,
 but any class is accepted.
 Returns kTRUE if successful, kFALSE otherwise.

 Remove the metadata obeject. If meta is 0 remove all meta data objects.
 Returns kTRUE if successful, kFALSE otherwise.

 Get meta data object with specified name. If meta is 0
 get first meta data object. Returns 0 in case no
 suitable meta data object is found.

 Compare TFileInfo object by their first urls.

 Print information about this object. If option contains 'L' a long listing
 will be printed (on multiple lines). Otherwise one line is printed with the
 following information: current url, default tree name|class|entries, md5;
 the default tree name is passed via the option ("T:<default_tree>") by the
 owning TFileCollection.
