Mikael Ståldal commented on LOG4J2-1329: ---------------------------------------- That's a good question. I wish that we do not have any such messages, and all messages implementing StringBuilderFormattable also implement the new interface. But otherwise I guess it would have to do as you suggested: * One way to solve this would be by asking the Message to write its contents into a second temporary buffer with formatTo(StringBuilder), and then process the data in that second buffer. > API change: let Message.getFormattedMessage() return CharSequence instead of > String > ----------------------------------------------------------------------------------- > > Key: LOG4J2-1329 > URL: https://issues.apache.org/jira/browse/LOG4J2-1329 > Project: Log4j 2 > Issue Type: Improvement > Components: API > Affects Versions: 2.5 > Reporter: Remko Popma > > I propose that we change {{Message.getFormattedMessage()}} to return a > {{CharSequence}} instead of a String. > I believe this change would be backwards compatible (all Message > implementations that return a String will work as is), and it opens the way > for zero-GC Message implementations to return a cached StringBuilder as > Mikael [suggested on the log4j-dev mailing > list|http://mail-archives.apache.org/mod_mbox/logging-log4j-dev/201603.mbox/%3CCAAFrFhSs4EqjOERwHObKAZP4wjGWeiCET1nyE1FVndYdePk2yw%40mail.gmail.com%3E]. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: log4j-dev-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-dev-h...@logging.apache.org
