Function documentation

void CreateProxy()

 Create the proxy object for our branch.

const char* GetBranchContentDataType(TBranch* branch, TString& contentTypeName, TDictionary*& dict) const

 Access a branch's collection content (not the collection itself)
 through a proxy.
 Retrieve the type of data contained in the collection stored by branch;
 put its dictionary into dict, If there is no dictionary, put its type
 name into contentTypeName.
 The contentTypeName is set to NULL if the branch does not
 contain a collection; in that case, the type of the branch is returned.
 In all other cases, NULL is returned.

TTreeReaderArrayBase(TTreeReader* reader, const char* branchname, TDictionary* dict)

{}

size_t GetSize() const

{ return fImpl->GetSize(GetProxy()); }

Bool_t IsEmpty() const

{ return !GetSize(); }

EReadStatus GetReadStatus() const

{ return fImpl ? fImpl->fReadStatus : kReadError; }

void* UntypedAt(size_t idx) const

{ return fImpl->At(GetProxy(), idx); }

TTreeReaderArrayBase(TTreeReader* reader, const char* branchname, TDictionary* dict)

 Create an array reader of branch "branchname" for TTreeReader "tr".
