ROOT::Experimental::RNTupleImporter::RImportLeafCountCollection Struct Reference

Leaf count arrays require special treatment.

They are translated into RNTuple untyped collections. This class does the bookkeeping of the sub-schema for these collections.

std::vector< size_t >	fImportFieldIndexes
	Points to the correspondings fields in fImportFields.
Int_t	fMaxLength = 0
	Stores count leaf GetMaximum() to create large enough buffers for the array leafs.
std::vector< std::unique_ptr< RImportTransformation > >	fTransformations
	One transformation for every field, to copy the content of the array one by one.
