method
thread
thread(algorithm, search_keys, charset)
public
As for #search(), but returns message sequence numbers in threaded format, as a Net::IMAP::ThreadMember tree. The supported algorithms are:
ORDEREDSUBJECT: | split into single-level threads according to subject, ordered by date. |
REFERENCES: | split into threads by parent/child relationships determined by which message is a reply to which. |
Unlike #search(), charset is a required argument. US-ASCII and UTF-8 are sample values.
See [SORT-THREAD-EXT] for more details.
