类 RegexLineTokenizer

  • 所有已实现的接口:
    LineTokenizer
    public class RegexLineTokenizer
extends AbstractLineTokenizer
    Line-tokenizer using a regular expression to filter out data (by using matching and non-matching groups). Consider the following regex which picks only the first and last name (notice the non-matching group in the middle): 
     (.*?)(?: .*)* (.*)
    For the names:
    • "Graham James Edward Miller"
    • "Andrew Gregory Macintyre"
    • "No MiddleName"
    the output will be:
    • "Miller", "Graham"
    • "Macintyre", "Andrew"
    • "MiddleName", "No"
    An empty list is returned, in case of a non-match.
