TArchiveFile::TArchiveFile | ( | const char * | archive, |
const char * | member, | ||
TFile * | file | ||
) |
Specify the archive name and member name.
[in] | archive | Name of the archive file |
[in] | member | Name of the ROOT file or integer number |
[in] | file | Address of the TFile instance from where the call takes place |
The member can be a decimal number which allows to access the n-th sub-file. This method is normally only called via TFile.

static |
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().
