## Class FromNetASCIIOutputStream

- java.lang.Object
- - java.io.OutputStream
  - - java.io.FilterOutputStream
    - - org.apache.commons.net.io.FromNetASCIIOutputStream

- All Implemented Interfaces:
    Closeable, Flushable, AutoCloseable

      public final class FromNetASCIIOutputStream
      extends FilterOutputStream

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

  Because of the translation process, a call to `flush()` will not flush the last byte written if that byte was a carriage return. A call to `close()` , however, will flush the carriage return.

    - #### FromNetASCIIOutputStream

          public FromNetASCIIOutputStream(OutputStream output)

      Creates a FromNetASCIIOutputStream instance that wraps an existing OutputStream.
      Parameters:
        `output` - The OutputStream to wrap.

  - ### Method Detail

    - #### write

          public void write(int ch)
                     throws IOException

      Writes a byte to the stream. Note that a call to this method might not actually write a byte to the underlying stream until a subsequent character is written, from which it can be determined if a NETASCII line separator was encountered. 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.

    - #### 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.

    - #### close

          public void close()
                     throws IOException

      Closes the stream, writing all pending data.
      Specified by:
        `close` in interface `Closeable`
      Specified by:
        `close` in interface `AutoCloseable`
      Overrides:
        `close` in class `FilterOutputStream`
      Throws:
        `IOException` - If an error occurs while closing the stream.
