All Implemented Interfaces:

org.apache.lucene.analysis.standard.StandardTokenizerConstants

public class FilenameFilter
extends org.apache.lucene.analysis.TokenFilter
implements org.apache.lucene.analysis.standard.StandardTokenizerConstants

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.
