All Implemented Interfaces:

Closeable

public class CharPosInputStream
extends InputStream

An InputStream that registers the position of the next character to read. This position can be a character offset or a combination of a line and column number. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r') , or a carriage return followed immediately by a linefeed ('\r\n').

Note: this class is only guaranteed to work correctly when the stream contains US-ASCII characters.
