public class AsciiOutputStream

extends java.io.FilterOutputStream

The AsciiOutputStream class acts as a filter to convert outgoing ASCII FTP streams from the system's local ASCII format by filtering and converting line termination strings. Note that the class as currently written will only handle \r\n or single character line termination strings; a more technically correct implementation would be preferable.

AsciiOutputStream

public AsciiOutputStream(java.io.OutputStream out)
                  throws java.lang.Exception

Creates an AsciiOutputStream by passing out to its superclass' constructor and determining the system-specific line termination string.

Parameters:

out - the underlying output stream.

Throws:

java.lang.Exception - if system line separator is longer than 1 char and is not \r\n

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the byte.

Throws:

java.io.IOException - if an I/O error occurs.

write

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

Writes b.length bytes to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the data to be written.

                  int len)
           throws java.io.IOException

Writes len bytes from the specified byte array starting at offset off to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.
