Subject [jira] [Resolved] (LOG4J2-1326) API change: add methods for logging CharSequences (was: Provide support for CharSequence parameters for low and zero-GC applications)
Date Thu, 07 Apr 2016 15:45:25 GMT

     [ https://issues.apache.org/jira/browse/LOG4J2-1326?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Remko Popma resolved LOG4J2-1326.
---------------------------------
    Resolution: Fixed

Fixed in master.

Adding these methods to the Logger interface:

{code}
debug(Marker, CharSequence)
debug(Marker, CharSequence, Throwable)
debug(CharSequence)
debug(CharSequence, Throwable)

// ... similar for the other log levels
{code}

Please verify and close.

> 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.
