Bool_t TFileInfo::AddMetaData ( TObject * meta )

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.

Bool_t TFileInfo::AddUrl	(	const char *	url,
		Bool_t	infront = `kFALSE`
	)

void TFileInfo::ParseInput ( const char * in )

private

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 occurrences for this object.
idx:<index> Index of this file if sorting with index

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

Definition at line 154 of file TFileInfo.cxx.

void TFileInfo::Print ( Option_t * option = "" ) const

virtual

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.

void TFileInfo::SetUUID ( const char * uuid )

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.
