instance method Net::IMAP#thread

thread(algorithm, search_keys, charset)

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.
