Classes
class	TArrayBranch
	When using TDataFrame to read data from a ROOT file, users can specify that the type of a branch is TArrayBranch<T> to indicate the branch is a c-style array, an STL array or any other type that can/must be accessed through a TTreeReaderArray<T> (as opposed to a TTreeReaderValue<T>). More...
