public MonitorOutputStream(OutputStream out)

Method Detail

close

public void close()
           throws IOException

Closes this output stream.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class FilterOutputStream

Throws:

IOException - if an error occurs.

write

public void write(int b)
           throws IOException

Overrides:

write in class BufferedOutputStream

Parameters:

b - The character to write.

Throws:

IOException - if an error occurs.

Since:

2.0

write

public void write(byte[] b,
         int off,
         int len)
           throws IOException

Overrides:

write in class BufferedOutputStream

Parameters:

b - The byte array.

off - The offset into the array.

len - The number of bytes to write.

Throws:

IOException - if an error occurs.

Since:

2.0

flush

public void flush()
           throws IOException

Specified by:

flush in interface Flushable

Overrides:

flush in class BufferedOutputStream

Throws:

IOException - if an error occurs.

Since:

2.0

write

public void write(byte[] b)
           throws IOException

Overrides:

write in class FilterOutputStream

Parameters:

b - The byte array.

Throws:

IOException - if an error occurs.

Since:

2.0

assertOpen

protected void assertOpen()
                   throws FileSystemException

check if file is still open.
This is a workaround for an oddity with Java's BufferedOutputStream where you can write to even if the stream has been closed

Throws:

FileSystemException - if an error occurs.

Since:

2.0

onClose

protected void onClose()
                throws IOException

Called after this stream is closed. This implementation does nothing.

Throws:

IOException - if an error occurs.
