Re: platform-independent version of /dev/null?

Ok this is from my head not tested so errors included ;) .

object PrintWriterx {
val NULL_DEVICE = "/dev/null"
object NULL_WRITER extends java.io.Writer {
override def flush(): Unit = { /* ignore */}
override def close(): Unit = {/* ignore */}
override def write(cbuf: Array[Char], off: Int, len: Int): Unit
{/*ignore this call*/}
}

def apply(fileName: String = NULL_DEVICE) = {
if(fileName == NULL_DEVICE) {
new PrintWriterx(NULL_DEVICE) extends java.io.PrintWriter(NULL_WRITER)
else
new PrintWriterx(fileName)
}

}
}
