      static java.util.regex.Pattern compile​(java.lang.String regex, java.lang.String flags)  
      static int flagsFromString​(java.lang.String flags)  
      static java.lang.String flagsToString​(int flags)  
      static boolean isMatchAllPattern​(java.lang.String str)  
      static boolean isSimpleMatchPattern​(java.lang.String str)
      Is the str a simple match pattern.
      static boolean simpleMatch​(java.lang.String[] patterns, java.lang.String str)
      Match a String against the given patterns, supporting the following simple pattern styles: "xxx*", "*xxx", "*xxx*" and "xxx*yyy" matches (with an arbitrary number of pattern parts), as well as direct equality.
      static boolean simpleMatch​(java.lang.String[] patterns, java.lang.String[] types)  
      static boolean simpleMatch​(java.lang.String pattern, java.lang.String str)
      Match a String against the given pattern, supporting the following simple pattern styles: "xxx*", "*xxx", "*xxx*" and "xxx*yyy" matches (with an arbitrary number of pattern parts), as well as direct equality.
      static boolean simpleMatch​(java.util.List<java.lang.String> patterns, java.lang.String str)
      Similar to simpleMatch(String[], String), but accepts a list of strings instead of an array of strings for the patterns to match.
      static org.apache.lucene.util.automaton.Automaton simpleMatchToAutomaton​(java.lang.String pattern)
      Return an Automaton that matches the given pattern.
      static org.apache.lucene.util.automaton.Automaton simpleMatchToAutomaton​(java.lang.String... patterns)
