Method from

output/java_guava/1.4.16/HostSpecifier.java:112–123

Attempts to return a HostSpecifier for the given string, throwing an exception if parsing fails. Always use this method in preference to #fromValid(String) for a specifier that is not already known to be valid. @throws ParseException if the specifier is not valid.

(String specifier)

  public static HostSpecifier from(String specifier) throws ParseException {
    try {
      return fromValid(specifier);
    } catch (IllegalArgumentException e) {
      // Since the IAE can originate at several different points inside
      // fromValid(), we implement this method in terms of that one rather
      // than the reverse.
      ParseException parseException = new ParseException("Invalid host specifier: " + specifier, 0);
      parseException.initCause(e);
      throw parseException;
    }
  }
