Catalyst::Log - Catalyst Log Class
$c->log->abort(1) if $c->log->can('abort');
+=head2 autoflush
+
+When enabled (default), messages are written to the log immediately instead
+of queued until the end of the request.
+
+This option, as well as C<abort>, is provided for modules such as
+L<Catalyst::Plugin::Static::Simple> to be able to programmatically
+suppress the output of log messages. By turning off C<autoflush> (application-wide
+setting) and then setting the C<abort> flag within a given request, all log
+messages for the given request will be suppressed. C<abort> can still be set
+independently of turning off C<autoflush>, however. It just means any messages
+sent to the log up until that point in the request will obviously still be emitted,
+since C<autoflush> means they are written in real-time.
+
+If you need to turn off autoflush you should do it like this (in your main app
+class):
+
+ after setup_finalize => sub {
+ my $c = shift;
+ $c->log->autoflush(0) if $c->log->can('autoflush');
+ };
+
=head2 _send_to_log
$log->_send_to_log( @messages );
You may subclass this module and override this method to get finer control
over the log output.

+Set the PSGI environment for this request. This ensures logs will be sent to
+the right place. If the environment has a C<psgix.logger>, it will be used. If
+not, we will send logs to C<psgi.errors> if that exists. As a last fallback, we
+will send to STDERR as before.
