TRemoteObject Class Reference

The TRemoteObject class provides protocol for browsing ROOT objects from a remote ROOT session.

It contains information on the real remote object as:

  • Object Properties (i.e. file stat if the object is a TSystemFile)
  • Object Name
  • Class Name
  • TKey Object Name (if the remote object is a TKey)
  • TKey Class Name (if the remote object is a TKey)
  • Remote object address
