Typedef Documentation

attrDataTuple

typedef std::tuple<std::string, std::string, void*> RootAuxDynIO::attrDataTuple

Definition at line 29 of file IRootAuxDynIO.h.

Function Documentation

auxBranchName()

std::string RootAuxDynIO::auxBranchName ( const std::string &  attr_name, const std::string &  baseBranchName  )

inline

Construct branch name for a given dynamic attribute.

Parameters

attr_name	the name of the attribute
baseBranchName	branch name for the main AuxStore object

Definition at line 60 of file RootAuxDynDefs.h.

{
   std::string branch_name = baseBranchName;
   if( !branch_name.empty() and branch_name.back() == '.' )  branch_name.pop_back();
   branch_name += RootAuxDynIO::AUXDYN_POSTFIX + attr_name;
   return branch_name;
}

auxFieldName()

std::string RootAuxDynIO::auxFieldName ( const std::string &  attr_name, const std::string &  baseName  )

inline

Construct field name for a given dynamic attribute.

Parameters

attr_name	the name of the attribute
baseBranchName	branch name for the main AuxStore object

Definition at line 69 of file RootAuxDynDefs.h.

{
   // RNTuple field names cannot contain dot characters '.'
   // Therefore, for now, we're using a colon instead ':'
   // This can be changed in the future
   std::string field_name = baseName;
   if (field_name.ends_with(':')) {
     field_name.pop_back();
   }
   field_name = std::format("{}Dyn:{}", field_name, attr_name);
   return field_name;
}

endsWithAuxPostfix()

bool RootAuxDynIO::endsWithAuxPostfix ( std::string_view  str )

inline

Check if a string ends with AUX_POSTFIX.

Parameters

str	the string to check

Definition at line 21 of file RootAuxDynDefs.h.

                                                      {
      return str.ends_with(AUX_POSTFIX);
   }

getKeyFromBranch()

std::string RootAuxDynIO::getKeyFromBranch

(

TBranch *

branch

)

Exctract the Aux object SG Key from the branch name.

Parameters

branch

TBranch with Key in its name

removeAuxPostfix()

bool RootAuxDynIO::removeAuxPostfix ( std::string &  str )

inline

if a string ends with AUX_POSTFIX then remove it

Parameters

str	the string to modify

Definition at line 49 of file RootAuxDynDefs.h.

{
   if( endsWithAuxPostfix(str) ) {
      str.resize( str.size() - AUX_POSTFIX_LEN );
      return true;
   }
   return false;
}
