TArchiveFile
This is an abstract class that describes an archive file containing
multiple sub-files, like a ZIP or TAR archive.
~TArchiveFile()
Dtor.
Long64_t GetMemberFilePosition() const
Return position in archive of current member.
Int_t GetNumberOfMembers() const
Returns number of members in archive.
Int_t SetMember(const char *member)
Explicitely make the specified member the current member.
Returns -1 in case of error, 0 otherwise.
Int_t SetMember(Int_t idx)
Explicitely make the member with the specified index the current member.
Returns -1 in case of error, 0 otherwise.
TArchiveFile* Open(const char *url, TFile *file)
Return proper archive file handler depending on passed url.
The handler is loaded via the plugin manager and is triggered by
the extension of the archive file. In case no handler is found 0
is returned. The file argument is used to access the archive.
The archive should be specified as url with the member name as the
anchor, e.g. "root://pcsalo.cern.ch/alice/event_1.zip#tpc.root",
where tpc.root is the file in the archive to be opened.
Alternatively the sub-file can be specified via its index number,
e.g. "root://pcsalo.cern.ch/alice/event_1.zip#3".
This function is normall only called via TFile::Open().
Bool_t ParseUrl(const char *url, TString &archive, TString &member)
Try to determine if url contains an anchor specifying an archive member.
Returns kFALSE in case of an error.
