ConsoleHandler
public ConsoleHandler()
Constructs a StreamHandler that publishes
log records to System.err. The initial
configuration is determined by the LogManager
properties described above.
close
public void close()
Forces any data that may have been buffered to the underlying
output device, but does
not close
System.err.
In case of an I/O failure, the
ErrorManager
of this
ConsoleHandler will be informed, but the caller
of this method will not receive an exception.
- close in interface StreamHandler
publish
public void publish(LogRecord record)
Publishes a
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.
- publish in interface StreamHandler
record - the log event to be published.
