Methods Summary
public final void	close() Writes all remaining throws IOException if there is an error. if (buffer.size() > 0) { processBuffer(); } super.close();
public final void	flush() Flush this log stream throws IOException if there is an error. if (buffer.size() > 0) { processBuffer(); }
protected void	processBuffer() Converts the buffer to a string and sends it to processLine throws IOException if there is an error. try { processLine(buffer.toString()); } finally { buffer.reset(); }
protected abstract void	processLine(java.lang.String line) Processes a line. param line the line to log. throws IOException if there is an error.
public final void	write(int cc) Write the data to the buffer and flush the buffer, if a line separator is detected. param cc data to log (byte). throws IOException if there is an error. final byte c = (byte) cc; if ((c == LF) || (c == CR)) { if (!skip) { processBuffer(); } } else { buffer.write(cc); } skip = (c == CR);
public final void	write(byte[] b, int off, int len) Write a block of characters to the output stream param b the array containing the data param off the offset into the array where data starts param len the length of block throws IOException if the data cannot be written into the stream. // find the line breaks and pass other chars through in blocks int offset = off; int blockStartOffset = offset; int remaining = len; while (remaining > 0) { while (remaining > 0 && b[offset] != LF && b[offset] != CR) { offset++; remaining--; } // either end of buffer or a line separator char int blockLength = offset - blockStartOffset; if (blockLength > 0) { buffer.write(b, blockStartOffset, blockLength); } while (remaining > 0 && (b[offset] == LF || b[offset] == CR)) { write(b[offset]); offset++; remaining--; } blockStartOffset = offset; }
