Constructor Detail

LoggerOutputStream

public LoggerOutputStream(Logger logger,
                          Logger.Level level,
                          int size)

Creates a logger output stream.

Parameters:

logger - the logger

level - one of org.tentackle.util.Level#SEVERE, etc...

size - the buffersize

LoggerOutputStream

public LoggerOutputStream(Logger logger,
                          Logger.Level level)

Creates a logger output stream with a default buffersize.

Parameters:

logger - the logger

level - one of org.tentackle.util.Level#SEVERE, etc...

LoggerOutputStream

public LoggerOutputStream(Logger logger)

Creates a logger output stream with a default buffersize and org.tentackle.util.Level#SEVERE.

Parameters:

logger - the logger

Method Detail

flush

public void flush()

Description copied from class: java.io.OutputStream

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

The flush method of OutputStream does nothing.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

close

public void close()

Description copied from class: java.io.ByteArrayOutputStream

Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

Specified by:

close in interface Closeable

Overrides:

close in class ByteArrayOutputStream

logException

public static void logException(Exception e,
                                Logger logger,
                                Logger.Level level,
                                int size)

Logs an exception stacktrace to the logger.

Parameters:

e - the exception

logger - the logger

level - the logging level

size - the buffersize

logException

public static void logException(Exception e,
                                Logger logger)

Logs an exception stacktrace to the logger with a default buffersize and org.tentackle.util.Level#SEVERE.

Parameters:

e - the exception

logger - the logger

logException

public static void logException(Exception e)

Logs an exception stacktrace to the logger with a default buffersize and org.tentackle.util.Level#SEVERE to the default logger of the util package.

Parameters:

e - the exception
