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.

 Constructor.

~TBranchProxy()

 Typical Destructor

void Reset()

 Completely reset the object.

void Print()

 Display the content of the object

Bool_t Setup()

 Initialize/cache the necessary information.

TBranchProxy()

TBranchProxy* GetProxy()

{ return this; }

Bool_t IsInitialized()

Bool_t IsaPointer() const

Bool_t Read()

Bool_t ReadEntries()

TClass * GetClass()

void* GetWhere() const

{ return fWhere; }

TVirtualCollectionProxy * GetCollection()

{ return fCollection; }

void * GetStart(UInt_t = 0)

 protected:

void * GetClaStart(UInt_t i = 0)

 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.

void * GetStlStart(UInt_t i = 0)

 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 STL Collection.

Int_t GetOffset()

{ return fOffset; }
