Function Documentation

string TClassEdit::CleanType ( const char *  typeDesc,
int  mode = 0,
const char **  tail = 0 
)

Cleanup type description, redundant blanks removed and redundant tail ignored return *tail = pointer to last used character if (mode==0) keep keywords if (mode==1) remove keywords outside the template params if (mode>=2) remove the keywords everywhere.

if (tail!=0) cut before the trailing *

The keywords currently are: "const" , "volatile" removed

CleanType(" A<B, C< D, E> > *,F,G>") returns "A<B,C<D,E> >*"

void TClassEdit::GetNormalizedName ( std::string &  norm_name,
std::string_view  name 
)

Return the normalized name.

See TMetaUtils::GetNormalizedName.

Return the type name normalized for ROOT, keeping only the ROOT opaque typedef (Double32_t, etc.) and removing the STL collections default parameter if any.

Compare to TMetaUtils::GetNormalizedName, this routines does not and can not add default template parameters.

int TClassEdit::GetSplit ( const char *  type,

Stores in output (after emptying it) the splited type.

Stores the location of the tail (nested names) in nestedLoc (0 indicates no tail). Return the number of elements stored.

First in list is the template name or is empty "vector<list<int>,alloc>**" to "vector" "list<int>" "alloc" "**" or "TNamed*" to "" "TNamed" "*"
