                                                                    reactor.util.context.Context context)

Use the given accessor to extract ThreadLocal values and save them in a sub-map in the given Context, so those can be restored later around the execution of data fetchers and exception resolvers. The accessor instance is also saved in the Reactor Context so it can be used to actually restore and reset ThreadLocal values.

Parameters:

accessor - the accessor to use

context - the context to write to if there are ThreadLocal values

Returns:

a new Reactor ContextView or the Context instance that was passed in, if there were no ThreadLocal values to extract.
