public final class ToNetASCIIInputStream
extends java.io.FilterInputStream

This class wraps an input 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

### ToNetASCIIInputStream

    public ToNetASCIIInputStream(java.io.InputStream input)

  Creates a ToNetASCIIInputStream instance that wraps an existing InputStream.

Parameters:
  `input` - The InputStream to .

Method Detail

### read

    public int read()
             throws java.io.IOException

  Reads and returns the next byte in the stream. If the end of the message has been reached, returns -1.

  Overrides:
    `read` in class `java.io.FilterInputStream`
  Returns:
    The next character in the stream. Returns -1 if the end of the stream has been reached.
  Throws:
    `java.io.IOException` - If an error occurs while reading the underlying stream.

### read

    public int read(byte[] buffer)
             throws java.io.IOException

  Reads the next number of bytes from the stream into an array and returns the number of bytes read. Returns -1 if the end of the stream has been reached.

  Overrides:
    `read` in class `java.io.FilterInputStream`
  Parameters:
    `buffer` - The byte array in which to store the data.
  Returns:
    The number of bytes read. Returns -1 if the end of the message has been reached.
  Throws:
    `java.io.IOException` - If an error occurs in reading the underlying stream.

### read

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

  Reads the next number of bytes from the stream into an array and returns the number of bytes read. Returns -1 if the end of the message has been reached. The characters are stored in the array starting from the given offset and up to the length specified.

  Overrides:
    `read` in class `java.io.FilterInputStream`
  Parameters:
    `buffer` - The byte array in which to store the data.
    `offset` - The offset into the array at which to start storing data.
    `length` - The number of bytes to read.
  Returns:
    The number of bytes read. Returns -1 if the end of the stream has been reached.
  Throws:
    `java.io.IOException` - If an error occurs while reading the underlying stream.

### markSupported

    public boolean markSupported()

  Returns false. Mark is not supported.

  Overrides:
    `markSupported` in class `java.io.FilterInputStream`

### available

    public int available()
                  throws java.io.IOException

  Overrides:
    `available` in class `java.io.FilterInputStream`
    `java.io.IOException`
