class ApplicationContext(application: Application, io_loop: IOLoop | None = None, url: str | None = None, logout_url: str | None = None)[source]#
Server-side holder for bokeh.application.Application plus any associated data. This holds data that’s global to all sessions, while ServerSession holds data specific to an “instance” of the application.
class BokehServerContext(application_context: ApplicationContext)[source]#
property sessions_: list[ServerSession]_#
SessionContext instances belonging to this application.
Subclasses must implement this method.

async with_locked_document(func: Callable[[Document], Awaitable[None]]) → None[source]#
Runs a function with the document lock held, passing the document to the function.
Subclasses must implement this method.
Parameters:
func (callable) – function that takes a single parameter (the Document) and returns None or a Future

If True, the session has been discarded and cannot be used.
A new session with the same ID could be created later but this instance will not come back to life.
