◆ GetFieldRange()

template<typename T>

ROOT::RNTupleGlobalRange ROOT::RNTupleViewBase< T >::GetFieldRange ( ) const

inlineinherited

Returns the global field range of this view.

This may differ from the RNTuple's entry range in case of subfields and can be used to iterate over all the concatenated elements of the subfield without caring which entry they belong to. Throws an RException if the underlying field of this view is empty, i.e. if it's a class or record field with no associated columns.
