This class implements the interface for entities represented by X.500 distinguished names (such as “CN=David,,C=US”). The constructor methods can accept the distinguished name in string form or in binary encoded form. getName( ) returns the name in string form, using the format defined by one of the three consant values. The no-argument version of getName( ) (the one defined by the Principal interface) returns the distinguished name formatted as specified by RFC 2253. Finally, getEncoded( ) returns a binary-encoded form of the name.
