Class NIOSeekableLineReaderFactory

java.lang.Object

org.archive.util.binsearch.impl.NIOSeekableLineReaderFactory

All Implemented Interfaces:

SeekableLineReaderFactory

public class NIOSeekableLineReaderFactory
extends Object
implements SeekableLineReaderFactory

A SeekableLineReaderFactory that opens a file ONCE at construction. Should be able to re-use the same FileChannel across threads, and might be more efficient than the RandomAccessFileSeekableLineReaderXXX classes.
