Constructor & Destructor Documentation

◆ TTreeReaderArrayBase()

ROOT::Internal::TTreeReaderArrayBase::TTreeReaderArrayBase ( TTreeReader reader,
const char *  branchname,
TDictionary dict 
)
inline

Definition at line 33 of file TTreeReaderArray.h.

Member Function Documentation

◆ CreateProxy()

void ROOT::Internal::TTreeReaderArrayBase::CreateProxy ( )
protectedvirtual

Create the proxy object for our branch.

Reimplemented from ROOT::Internal::TTreeReaderValueBase.

Definition at line 331 of file TTreeReaderArray.cxx.

◆ GetBranchAndLeaf()

bool ROOT::Internal::TTreeReaderArrayBase::GetBranchAndLeaf ( TBranch *&  branch,
TLeaf *&  myLeaf,
TDictionary *&  branchActualType 
)
protected

Determine the branch / leaf and its type; reset fProxy / fSetupStatus on error.

Definition at line 461 of file TTreeReaderArray.cxx.

◆ GetBranchContentDataType()

const char * ROOT::Internal::TTreeReaderArrayBase::GetBranchContentDataType ( TBranch branch,
TString contentTypeName,
TDictionary *&  dict 
)
protected

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.
