How can I decltype the type of a variable which in the entry of Tree branch?
I want to read a variable from a Tree, but I don’t know the type of the variable. I hope I can use decltype function but not use GetColumnType().
There is no direct implementation of
decl_type in the way you describe.
However you can get the same net effect (use the data without knowing or looking up the type) by using the
RDataFrame (Dataframes - ROOT)
