Functions:

register_selection_context(actor_provider, ...)	Registers request identity and write-access checks for selection APIs.
get_actor()	Returns the current actor, or None for local SDK operations.
check_access(dataset, action)	Raises if the registered policy denies a selection write.

fiftyone.core.selection_context.register_selection_context(actor_provider, access_checker)

Registers request identity and write-access checks for selection APIs.

The access checker receives a dataset and either "edit" or "tag". It must raise before a denied operation. The actor provider is evaluated in the caller’s context, including background workers. Without a provider, selection operations use the local SDK’s unrestricted access.

Returns:

a function that restores the previous registration

fiftyone.core.selection_context.get_actor()

Returns the current actor, or None for local SDK operations.

fiftyone.core.selection_context.check_access(dataset, action)

Raises if the registered policy denies a selection write.
