[jira] [Comment Edited] (LOG4J2-1326) API change: add methods for
logging CharSequences (was: Provide support for CharSequence parameters for
low and zero-GC applications)
[ https://issues.apache.org/jira/browse/LOG4J2-1326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15211947#comment-15211947 ]

What happens to the String version of the methods? Should they be deprecated? How is having debug(CS) going to work when it is time to convert to a byte[]? Just dona toString() I guess.

> Key: LOG4J2-1326
> URL: https://issues.apache.org/jira/browse/LOG4J2-1326
> Project: Log4j 2
> Issue Type: New Feature
> Components: API
> Affects Versions: 2.5
> Reporter: Vlad Shurupov
> Labels: features, performance
>
> Currently, the preferred way of logging character sequences in log4j 2 is by passing in tokens of type {{java.lang.String}}. It would be very beneficial if the API could provide methods that take {{java.lang.CharSequence}} tokens. This would allow high performance zero or low-GC applications to re-use the existing mutable structures implementing {{java.lang.CharSequence}} for continuous logging without new objects being created.
> A high-performance implementation of the logger would be expected to copy out the contents of a single or multiple instances of {{java.lang.CharSequence}} so that they could be re-used in the subsequent logging call.
