public void publish(LogRecord record)
LogRecord
to the console, provided the
record passes all tests for being loggable.
Most applications do not need to call this method directly.
Instead, they will use use a Logger
, which will
create LogRecords and distribute them to registered handlers.
In case of an I/O failure, the ErrorManager
of this SocketHandler
will be informed, but the caller
of this method will not receive an exception.
The GNU implementation of ConsoleHandler.publish
calls flush() for every request to publish a record, so
they appear immediately on the console.
