The SubscribeSubject operator is essentially a source which accesses a subject with the specified name, at the same scope level or above, and subscribes to it. The behavior of SubscribeSubject is defined by the type of the subject which is accessed, and values from the shared underlying sequence will then be passed to any operators downstream from SubscribeSubject, as if these operators were connected to the subject directly.

Note

If the definition of the underlying subject changes, there is no need to change the SubscribeSubject as long as the name remains the same.
