Examples of LineNumberInputStream

java.io.LineNumberInputStream
This class is an input stream filter that provides the added functionality of keeping track of the current line number.
A line is a sequence of bytes ending with a carriage return character ('\r'), a newline character ('\n'), or a carriage return character followed immediately by a linefeed character. In all three cases, the line terminating character(s) are returned as a single newline character.
The line number begins at 0, and is incremented by 1 when a read returns a newline character. @author Arthur van Hoff @version 1.28, 11/17/05 @see java.io.LineNumberReader @since JDK1.0 @deprecated This class incorrectly assumes that bytes adequately representcharacters. As of JDK 1.1, the preferred way to operate on character streams is via the new character-stream classes, which include a class for counting line numbers.

InputStream used by the parser to wrap the original user supplied stream. This stream keeps track of the current line number.
