Here is the call graph for this function:

template<typename NamedTuple >

dfe::NamedTupleRootWriter< NamedTuple >::NamedTupleRootWriter ( TDirectory *  dir, const std::string &  tree_name  )

inline

Create a tree in a ROOT directory. Overwrites existing data.

Parameters

dir	Output directory for the tree
tree_name	Name of the output tree relative to the directory

When the writer is created with an existing ROOT directory, the user is responsible for ensuring the underlying file is closed.
