Function documentation

TArchiveFile(const char* archive, const char* member, TFile* file)

 Specify the archive name and member name. The member can be a decimal
 number which allows to access the n-th sub-file. This method is
 normally only called via TFile.

~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 normally only called via TFile::Open().

Bool_t ParseUrl(const char* url, TString& archive, TString& member, TString& type)

 Try to determine if url contains an anchor specifying an archive member.
 Returns kFALSE in case of an error.
