inlinefinalvirtual

Override this method to register a callback that is executed before the processing a new data sample starts.

The callback will be invoked in the same conditions as with DefinePerSample().

◆ MakeNew()

ROOT::Internal::RDF::UntypedSnapshotTTreeHelper ROOT::Internal::RDF::UntypedSnapshotTTreeHelper::MakeNew	(	void *	newName,
		std::string_view	= "nominal" )

Create a new UntypedSnapshotTTreeHelper with a different output file name.

Parameters

newName A type-erased string with the output file name

Returns: UntypedSnapshotTTreeHelper

This MakeNew implementation is tied to the cloning feature of actions of the computation graph. In particular, cloning a Snapshot node usually also involves changing the name of the output file, otherwise the cloned Snapshot would overwrite the same file.
