public final class ToNetASCIIOutputStream

extends java.io.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 Detail

ToNetASCIIOutputStream

public ToNetASCIIOutputStream(java.io.OutputStream output)

Creates a ToNetASCIIOutputStream instance that wraps an existing OutputStream.

Parameters:

output - The OutputStream to wrap.

Method Detail

write

public void write(int ch)
           throws java.io.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 java.io.FilterOutputStream

Parameters:

ch - The byte to write.

Throws:

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

write

public void write(byte[] buffer)
           throws java.io.IOException

Writes a byte array to the stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

buffer - The byte array to write.

Throws:

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

write

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

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

Overrides:

write in class java.io.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:

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