A branch containing and managing a TRefTable for TRef autoloading.

It loads the TBranch containing a referenced object when requested by TRef::GetObject(), so the reference can be resolved. The information which branch to load is stored by TRefTable. Once a TBranch has read the TBranchRef's current entry it will not be told to re-read, in case the use has changed objects read from the branch.

LIMITATION ***

Note that this does NOT allow for autoloading of references spanning different entries. The TBranchRef's current entry has to correspond to the entry of the TBranch containing the referenced object.

The TRef cannot be stored in a top-level branch which is a TBranchObject for the auto-loading to work. E.g. you cannot store the TRefs in TObjArray, and create a top-level branch storing this TObjArray.
