Subject [jira] Commented: (MIME4J-6) Loading bodies on demand instead of using temporary files
Date Wed, 19 Sep 2007 09:12:43 GMT

    [ https://issues.apache.org/jira/browse/MIME4J-6?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12528701

Niklas Therning commented on MIME4J-6:
--------------------------------------

If the mail is read from disk Mime4j could scan it first to find the boundaries of the body
parts. It would then store the start and end file positions of each part. When a body part
is requested it would read that particular portion of the message from the file using the
start and end positions. The header of each part could probably be kept in memory.

One drawback compared to the temporary file solution would be that when using temporary files
the decoded part data can be stored directly. The decoding is only done once. One could also
use a hybrid solution: decoded parts are stored in temp files the first time they are decoded.

Temporary files would also still have to be used I guess if the message isn't read from disk
(no underlying FileChannel/RandomAccessFile).
