public final class FromNetASCIIInputStream
This class wraps an input 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.

FromNetASCIIInputStream(InputStream input)
Creates a FromNetASCIIInputStream instance that wraps an existing InputStream. |
Method Summary | |
---|---|
int |
available()
Returns the number of bytes that can be read without blocking EXCEPT when newline conversions have to be made somewhere within the available block of bytes. |
static boolean |
isConversionRequired()
Returns true if the NetASCII line separator differs from the system line separator, false if they are the same. |
int |
read()
Reads and returns the next byte in the stream. |
int |
read(byte[] buffer)
Reads the next number of bytes from the stream into an array and returns the number of bytes read. |
int |
read(byte[] buffer,
int offset,
int length)
Reads the next number of bytes from the stream into an array and returns the number of bytes read. |
