LogWriter
public LogWriter(java.io.Writer o,
java.io.Writer log)
- EscapeWriter constructor comment.
- Parameters:
o
- java.io.Writerlog
-
close
public void close()
throws java.io.IOException
- Close the stream, flushing it first. Once a stream has been closed,
further write() or flush() invocations will cause an IOException to be
thrown. Closing a previously-closed stream, however, has no effect.
- Specified by:
close
in interface java.io.Closeable
- Overrides:
close
in class java.io.FilterWriter
- Throws:
java.io.IOException
- If an I/O error occurs
flush
public void flush()
throws java.io.IOException
- Flush the stream. If the stream has saved any characters from the various
write() methods in a buffer, write them immediately to their intended
destination. Then, if that destination is another character or byte
stream, flush it. Thus one flush() invocation will flush all the buffers
in a chain of Writers and OutputStreams.
- Specified by:
flush
in interface java.io.Flushable
- Overrides:
flush
in class java.io.FilterWriter
- Throws:
java.io.IOException
