  public DNComparator()
Method Details
- preNormalize
  
  public static String preNormalize(String dn)
  
  Returns a form of the original DN which will be properly parsed by JDK X500Principal class by replacing attribute names unknown by the X500Principal with OIDs. What is more all DC and EMAIL values are converted to lower case.
  
  Parameters:
  
  dn - in RFC 2253 form.
  
  Returns:
  
  dn in RFC 2253 form, reformatted.
- getHashCode
  
  public static int getHashCode(String dn)
  
  Parameters:
  
  dn - source dn
  
  Returns:
  
  hashcode useful as a return value of the hshCode() method, when equals is overriden to use X500NameUtils equals method.
- upLowCase
  
  private static String upLowCase(String src)
  
  Uppers the case of the arg, then lowers it, using non-locale specific algorithm.
  
  Parameters:
  
  src - source string.
  
  Returns:
  
  modified string.
- normalizeAVA
  
  private static org.bouncycastle.asn1.x500.AttributeTypeAndValue normalizeAVA(org.bouncycastle.asn1.x500.AttributeTypeAndValue orig)
