classmethod behavior()[source]#

Behaviors necessary to implement this schema

classmethod uproot_writeable(events)[source]#

Converting BaseSchema events into something that is uproot writeable. BaseSchema leaves every original branch as a top-level field, so this just packs each uproot-compatible field into a dict ready for uproot.WritableDirectory.mktree.

Subclasses that apply non-trivial zipping during construction should override this with a schema-specific inverse.

Parameters:

events (NanoEvents) – The BaseSchema events to be turned into something uproot-writeable

Returns:

out – An uproot-writeable dictionary representing the same information as the input events

Return type:

dict
