Package org.commonmark.internal.util

Class LineReader

java.lang.Object

org.commonmark.internal.util.LineReader

All Implemented Interfaces:

Closeable, AutoCloseable

public class LineReader
extends Object
implements Closeable

Reads lines from a reader like BufferedReader but also returns the line terminators.

Line terminators can be either a line feed "\n", carriage return "\r", or a carriage return followed by a line feed "\r\n". Call getLineTerminator() after readLine() to obtain the corresponding line terminator. If a stream has a line at the end without a terminator, getLineTerminator() returns null.
