FILE *out = fopen("memfile_dump.root", "wb");

◆ EnableParBranchProcessing()

void ROOT::Internal::EnableParBranchProcessing ( )

Globally enables the parallel branch processing, which is a case of implicit multi-threading (IMT) in ROOT, activating the required locks.

This IMT use case, implemented in TTree::GetEntry, spawns a task for each branch of the tree. Therefore, a task takes care of the reading, decompression and deserialisation of a given branch.

◆ NeedsMetaNameAsAlias()

bool ROOT::Internal::NeedsMetaNameAsAlias	(	const std::string &	metaNormalizedName,

Checks if the meta normalized name is different from the RNTuple normalized name in a way that would cause the RNTuple normalized name to request different streamer info.

This can happen, e.g., if the type name has Long64_t as a template parameter. In this case, RNTuple should use the meta normalized name as a type alias to ensure correct reconstruction of objects from disk. If the function returns true, renormalizedAlias contains the RNTuple normalized name that should be used as type alias.
