Dear experts,
Any suggestions for solving a problem described below?
We have created a root file which contains a couple ntuples and is then saved to a local disk. This root file is then read in via fread and saved into a database as a string of characters. In another application, we could retrieve this file from the same database and used fwrite to save it to disk. This procedure works fine without any problems at all. However, for our other applications, we want to retrieve this file from the database and then access it directly without ever writing it to a local disk. Since what we get back from the database is a string of characters, how could we extract out those ntuples from it or map it to a memory resident TFile?
Thanks,
Xiaochun He
