Make the provided Context Context.current() for the creation of a listener to a received call and for all events received by that listener.

This utility is expected to be used by ServerInterceptor implementations that need to augment the Context in which the application does work when receiving events from the client.

Parameters:

context - to make Context.current().

method - being requested by the client.

call - used to send responses to client.

headers - received from client.

next - handler used to create the listener to be wrapped.

Returns:

listener that will receive events in the scope of the provided context.
