Class FilenameFilter

  • All Implemented Interfaces:
    Closeable, AutoCloseable

    public class FilenameFilter
    extends org.apache.lucene.analysis.TokenFilter
    This filter tokenises filenames using .-_ as delimiters. It is needed because the StandardTokenizer does not work very well with filenames - it does not split on . unless followed by a space and does not split on _ if the next term begins with a number.
