ROOT::Experimental::RNTupleViewBase< T > Class Template Reference

template<typename T>
class ROOT::Experimental::RNTupleViewBase< T >

An RNTupleView provides read-only access to a single field of the ntuple.

Template Parameters

T	The type of the object that will be read by the view; can be void if unknown at compile time.

The view owns a field and its underlying columns in order to fill an RField::RValue object with data. Data can be accessed by index. For top-level fields, the index refers to the entry number. Fields that are part of nested collections have global index numbers that are derived from their parent indexes.

View can only be created by a reader or by a collection view.
