Class BigBinarySearcher

java.lang.Object

org.riversun.finbin.BinarySearcher

org.riversun.finbin.BigBinarySearcher

public class BigBinarySearcher
extends BinarySearcher

Search target big bytes(byte[]) from source bytes(byte[])

This class is going to scan byte[] data in concurrent by using threads, it is effective(means faster speed) in big size(kiloBytes-megaBytes) byte[] data.
