class ROOT::TBranchProxy


TBranchProxy

 Base class for all the proxy object.  It includes the imeplemtation
 of the autoloading of branches as well as all the generic setup
 routine.

 return the address of the start of the object being proxied. Assumes
 that Setup() has been called.  Assumes the object containing this data
 member is held in TClonesArray.
