Class SingleThreadedUASparser

java.lang.Object

cz.mallat.uasparser.UASparser

cz.mallat.uasparser.SingleThreadedUASparser

Direct Known Subclasses:

MultithreadedUASparser

public class SingleThreadedUASparser
extends UASparser

This parser implementation is not thread-safe as it re-uses Matcher objects instead of creating them on each call to parse() for a modest speedup. Recommended for single-threaded scenarios, such as Hadoop map/reduce jobs.
