Field Detail

LINE_SEPERATOR

protected static final String LINE_SEPERATOR

hasBeenClosed

protected boolean hasBeenClosed
Used to maintain the contract of close().


buf

protected byte[] buf
The internal buffer where data is stored.


count

protected int count
The number of valid bytes in the buffer. This value is always in the range 0 through buf.length; elements buf[0] through buf[count-1] contain valid byte data.


DEFAULT_BUFFER_LENGTH

public static final int DEFAULT_BUFFER_LENGTH
The default number of bytes in the buffer. =2048

Constructor Detail

LoggingOutputStream

public LoggingOutputStream(org.slf4j.Logger logger,
                           Level level)
Method Detail

close

public void close()
Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

Specified by:
close in interface Closeable
Overrides:
close in class OutputStream

write

public void write(int b)
           throws IOException
Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Specified by:
write in class OutputStream
Parameters:
b - the byte to write
Throws:
IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

flush

public void flush()
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.

Specified by:
flush in interface Flushable
Overrides:
flush in class OutputStream
