LogOutputStreampublic class LogOutputStream extends OutputStream | Capture output lines and send them to the system error log. |
| Fields Summary |
|---|
| protected Logger | logger | | protected Level | level | | private int | lastb | | private byte[] | buf | | private int | pos |
| Constructors Summary |

public LogOutputStream(String facility)Log to the specified facility at the default FINE level.
this(facility, Level.FINE);
| public LogOutputStream(String facility, Level level)Log to the specified facility at the specified level.
logger = Logger.getLogger(facility);
this.level = level;

| Methods Summary |
|---|
| private void | expandCapacity(int len)Ensure that the buffer can hold at least len bytes
beyond the current position.
while (pos + len > buf.length) {
byte[] nb = new byte[buf.length * 2];
System.arraycopy(buf, 0, nb, 0, pos);
buf = nb;
}
| | protected void | log(java.lang.String msg)Log the specified message.
Can be overridden by subclass to do different logging.
logger.log(level, msg);
| | private void | logBuf()Convert the buffer to a string and log it.
String msg = new String(buf, 0, pos);
pos = 0;
log(msg);
| | public void | write(int b)
if (!logger.isLoggable(level))
return;
if (b == '\r") {
logBuf();
} else if (b == '\n") {
if (lastb != '\r")
logBuf();
} else {
expandCapacity(1);
buf[pos++] = (byte)b;
}
lastb = b;
| | public void | write(byte[] b)
write(b, 0, b.length);
| | public void | write(byte[] b, int off, int len)
int start = off;
if (!logger.isLoggable(level))
return;
len += off;
for (int i = start; i < len ; i++) {
if (b[i] == '\r") {
expandCapacity(i - start);
System.arraycopy(b, start, buf, pos, i - start);
pos += i - start;
logBuf();
start = i + 1;
} else if (b[i] == '\n") {
if (lastb != '\r") {
expandCapacity(i - start);
System.arraycopy(b, start, buf, pos, i - start);

}
if ((len - start) > 0) {
expandCapacity(len - start);
