 * A general interface for matching a URI against a URI pattern. Guice-servlet provides regex and
 * servlet-style pattern matching out of the box.
 * @author (Dhanji R. Prasanna)
interface UriPatternMatcher {
   * @param uri A "contextual" (i.e. relative) and "normalized" Request URI, *not* a complete one.
   * @return Returns true if the uri matches the pattern.
  boolean matches(String uri);

   * @param pattern The Path that this service pattern can match against.
   * @return Returns a canonical servlet path from this pattern. For instance, if the pattern is
   *         {@code /home/*} then the path extracted will be {@code /home}. Each pattern matcher
   *         implementation must decide and publish what a canonical path represents.
   *         NOTE(dhanji): This method returns null for the regex pattern matcher.
  String extractPath(String pattern);
  /** Returns the type of pattern this is. */
  UriPatternType getPatternType();

  /** Returns the original pattern that was registered. */
