I3ROOTTableService

class I3ROOTTableService

encapsulates a root file and provides methods of writing data to that ROOT file in the tableio framework.

I3ROOTTableService(const std::string &filename, const std::string &master = "MasterTree", int compress = 1, long long maxSize, const std::string &mode = "RECREATE")

creates a new I3ROOTTableService with the given parameters:

• filename - Name of the ROOT files to be written;

• master - Name of the master tree in the ROOT file. All other trees are friends of this tree.

• compress - Compression parameter. See the documentation of TFile in the ROOT documentation for the meaning of this number. The default should be okay for most people.

• maxSize - Maximum file size. When reaching this size, ROOT will automatically split the files. You should be aware that split files have to be read in a chain. Otherwise they might not be aligned correctly.

• mode - The file mode of the ROOT file. See the documentation of TFile in the ROOT documentation. Only change this if you really know what you are doing!

All other functions are private/protected and do not need to be accessed by the user.
