ROOT::Internal::TFileImplBase Class Reference

Base class for storage-specific ROOT file implementations.

A class deriving from TFileImplBase is an object store: it can serialize any object for which ROOT I/O is available (generally: an object which has a dictionary), and it stores the object's data under a key name.

A TFileImplBase stores whatever was added to it as a TDirectory, when the TFileImplBase object is destructed. It can store non-lifetime managed objects by passing them to Save().
