dodal.plans.data_session_metadata

Functions

attach_data_session_metadata_decorator(plan)	Attach data session metadata to the runs within a plan and make it correlate with an ophyd-async PathProvider.
attach_data_session_metadata_wrapper(plan[, ...])	Attach data session metadata to the runs within a plan and make it correlate with an ophyd-async PathProvider.

dodal.plans.data_session_metadata.attach_data_session_metadata_wrapper(plan: Generator[Msg, Any, P], provider: UpdatingPathProvider | None = None) → Generator[Msg, Any, P]

Attach data session metadata to the runs within a plan and make it correlate with an ophyd-async PathProvider.

This updates the path provider (which in turn makes a call to to a service to figure out which scan number we are using for such a scan), and ensures the start document contains the correct data session.

Parameters:

• plan (Generator[Msg, Any, TypeVar(P)]) – The plan to preprocess

• provider (UpdatingPathProvider | None, default: None) – The path provider that participating detectors are aware of.

Returns:

A plan

Return type:

MsgGenerator

Yields:

Iterator[Msg] – Plan messages
