TEntryListFromFile Class Reference

Manages entry lists from different files, when they are not loaded in memory at the same time.

This entry list should only be used when processing a TChain (see TChain::SetEntryList() function). File naming convention:

  • by default, filename_elist.root is used, where filename is the name of the chain element.
  • xxx$xxx.root - $ sign is replaced by the name of the chain element If the list name is not specified (by passing filename_elist.root/listname to the TChain::SetEntryList() function, the first object of class TEntryList in the file is taken. It is assumed that there are as many lists, as there are chain elements, and they are in the same order.

If one of the list files can't be opened, or there is an error reading a list from the file, this list is skipped and the entry loop continues on the next list.
