Class BufferedLineReader

java.lang.Object

htsjdk.samtools.util.BufferedLineReader

All Implemented Interfaces:

LineReader, java.io.Closeable, java.lang.AutoCloseable

public class BufferedLineReader
extends java.lang.Object
implements LineReader

Implementation of LineReader that is a thin wrapper around BufferedReader. On Linux, this is faster than AsciiLineReaderImpl. If you use AsciiLineReader rather than this class, it will detect the OS and delegate to the preferred implementation. TODO: Replace this with LineNumberReader?
