org.apache.commons.net.io.ToNetASCIIOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public final class ToNetASCIIOutputStream
extends FilterOutputStream

This class wraps an output stream, replacing all singly occurring <LF> (linefeed) characters with <CR><LF> (carriage return followed by linefeed), which is the NETASCII standard for representing a newline. You would use this class to implement ASCII file transfers requiring conversion to NETASCII.

Constructor Details

ToNetASCIIOutputStream

public ToNetASCIIOutputStream(OutputStream output)

Creates a ToNetASCIIOutputStream instance that wraps an existing OutputStream.

Parameters:

output - The OutputStream to wrap.

Method Details

write

public void write(byte[] buffer)
           throws IOException

Writes a byte array to the stream.

Overrides:

write in class FilterOutputStream

Parameters:

buffer - The byte array to write.

Throws:

IOException - If an error occurs while writing to the underlying stream.

write

public void write(byte[] buffer,
 int offset,
 int length)
           throws IOException

Writes a number of bytes from a byte array to the stream starting from a given offset.

Overrides:

write in class FilterOutputStream

Parameters:

buffer - The byte array to write.

offset - The offset into the array at which to start copying data.

length - The number of bytes to write.

Throws:

IOException - If an error occurs while writing to the underlying stream.

write

public void write(int ch)
           throws IOException

Writes a byte to the stream. Note that a call to this method may result in multiple writes to the underlying input stream in order to convert naked newlines to NETASCII line separators. This is transparent to the programmer and is only mentioned for completeness.

Overrides:

write in class FilterOutputStream

Parameters:

ch - The byte to write.

Throws:

IOException - If an error occurs while writing to the underlying stream.
