- Section Extraction Protocol implementation.
-
- Stream database is implemented as a linked list of section streams,
- where each stream contains a linked list of children, which may be leaves or
- encapsulations.
-
- Children that are encapsulations generate new stream entries
- when they are created. Streams can also be created by calls to
- SEP->OpenSectionStream().
-
- The database is only created far enough to return the requested data from
- any given stream, or to determine that the requested data is not found.
-
- If a GUIDed encapsulation is encountered, there are three possiblilites.
-
- 1) A support protocol is found, in which the stream is simply processed with
- the support protocol.
-
- 2) A support protocol is not found, but the data is available to be read
- without processing. In this case, the database is built up through the
- recursions to return the data, and a RPN event is set that will enable
- the stream in question to be refreshed if and when the required section
- extraction protocol is published.This insures the AuthenticationStatus
- does not become stale in the cache.
-
- 3) A support protocol is not found, and the data is not available to be read
- without it. This results in EFI_PROTOCOL_ERROR.
