#verify_session(session_id, quiet = false) ⇒ session, ... (protected)

verifies that a given session_id is valid and that the session is interactive. The various return values allow the caller to make better decisions on what action can & should be taken depending on the capabilities of the session and the caller’s objective while making it simple to use in the nominal case where the caller needs session_id to match an interactive session

Parameters:

  • session_id (String) —

    A session id, which is an integer as a string

  • quiet (Boolean) (defaults to: false) —

    True means the method will produce no error messages

Returns:

  • (session) —

    if the given session_id is valid and session is interactive

  • (false) —

    if the given session_id is valid, but not interactive

  • (nil) —

    if the given session_id is not valid at all
