public X500Principal(String name)
X500Principal
from a string representation of
an X.500 distinguished name (ex:
"CN=Duke, OU=JavaSoft, O=Sun Microsystems, C=US").
The distinguished name must be specified using the grammar defined in
RFC 1779 or RFC 2253 (either format is acceptable).
This constructor recognizes the attribute type keywords
defined in RFC 1779 and RFC 2253
(and listed in getName(String format)
),
as well as the T, DNQ or DNQUALIFIER, SURNAME, GIVENNAME, INITIALS,
GENERATION, EMAILADDRESS, and SERIALNUMBER keywords whose OIDs are
defined in RFC 2459 and its successor.
Any other attribute type must be specified as an OID.

X500Principal
from a string representation of
an X.500 distinguished name (ex:
"CN=Duke, OU=JavaSoft, O=Sun Microsystems, C=US").
The distinguished name must be specified using the grammar defined in
RFC 1779 or RFC 2253 (either format is acceptable).
This constructor recognizes the attribute type keywords specified
in X500Principal(String)
and also recognizes additional
keywords that have entries in the keywordMap
parameter.
Keyword entries in the keywordMap take precedence over the default
keywords recognized by X500Principal(String)
. Keywords
MUST be specified in all upper-case, otherwise they will be ignored.
Improperly specified keywords are ignored; however if a keyword in the
name maps to an improperly specified OID, an
IllegalArgumentException
is thrown. It is permissible to
have 2 different keywords that map to the same OID.

The read position of the input stream is positioned to the next available byte after the encoded distinguished name.

public String getName()
This method is equivalent to calling
getName(X500Principal.RFC2253)
.
X500Principal
public String getName(String format)
If "RFC1779" is specified as the format, this method emits the attribute type keywords defined in RFC 1779 (CN, L, ST, O, OU, C, STREET). Any other attribute type is emitted as an OID.
If "RFC2253" is specified as the format, this method emits the attribute type keywords defined in RFC 2253 (CN, L, ST, O, OU, C, STREET, DC, UID). Any other attribute type is emitted as an OID. Under a strict reading, RFC 2253 only specifies a UTF-8 string representation. The String returned by this method is the Unicode string achieved by decoding this UTF-8 representation.
If "CANONICAL" is specified as the format, this method returns an RFC 2253 conformant string representation with the following additional canonicalizations:
String.toUpperCase(Locale.US)
String.toLowerCase(Locale.US)
Additional standard formats may be introduced in the future.
format
- the format to use
X500Principal
using the specified format
IllegalArgumentException
- if the specified format is invalid
or nullpublic String getName(String format, Map<String,String> oidMap)
IllegalArgumentException
will be thrown.
This method returns Strings in the format as specified in
getName(String)
and also emits additional attribute type
keywords for OIDs that have entries in the oidMap
parameter. OID entries in the oidMap take precedence over the default
OIDs recognized by getName(String)
.
Improperly specified OIDs are ignored; however if an OID
in the name maps to an improperly specified keyword, an
IllegalArgumentException
is thrown.
Additional standard formats may be introduced in the future.
Warning: additional attribute type keywords may not be recognized by other implementations; therefore do not use this method if you are unsure if these keywords will be recognized by other implementations.
format
- the format to useoidMap

that maps to a corresponding attribute type keyword String.
The map may be empty but never null

method)
of this object and o are equal.
This implementation is compliant with the requirements of RFC 2459.
