public class RdnParser
extends Object
This class parse the name-component part or the following BNF grammar (as of
RFC2253, par. 3, and RFC1779, fig. 1) :
- <name-component> ::=
<attributeType> <spaces> '=' <spaces>
<attributeValue> <attributeTypeAndValues>
-
<attributeTypeAndValues> ::= <spaces> '+' <spaces>
<attributeType> <spaces> '=' <spaces>
<attributeValue> <attributeTypeAndValues> | e
-
<attributeType> ::= [a-zA-Z] <keychars> | <oidPrefix> [0-9]
<digits> <oids> | [0-9] <digits> <oids>
-
<keychars> ::= [a-zA-Z] <keychars> | [0-9] <keychars> | '-'
<keychars> | e
- <oidPrefix> ::= 'OID.' | 'oid.' | e
-
<oids> ::= '.' [0-9] <digits> <oids> | e
-
<attributeValue> ::= <pairs-or-strings> | '#' <hexstring>
|'"' <quotechar-or-pairs> '"'
- <pairs-or-strings> ::= '\'
<pairchar> <pairs-or-strings> | <stringchar>
<pairs-or-strings> | e
- <quotechar-or-pairs> ::=
<quotechar> <quotechar-or-pairs> | '\' <pairchar>
<quotechar-or-pairs> | e
- <pairchar> ::= ',' | '=' | '+' |
'<' | '>' | '#' | ';' | '\' | '"' | [0-9a-fA-F] [0-9a-fA-F]
-
<hexstring> ::= [0-9a-fA-F] [0-9a-fA-F] <hexpairs>
-
<hexpairs> ::= [0-9a-fA-F] [0-9a-fA-F] <hexpairs> | e
-
<digits> ::= [0-9] <digits> | e
- <stringchar> ::=
[0x00-0xFF] - [,=+<>#;\"\n\r]

<spaces> | e
A RDN is a part of a DN. It can be composed of many types, as in the RDN
following RDN :
ou=value + cn=other value
In this case, we have to store an 'ou' and a 'cn' in the RDN.
The types are case insensitive.
Spaces before and after types and values are not stored.
Spaces before and after '+' are not stored.
Thus, we can consider that the following RDNs are equals :
'ou=test 1'
' ou=test 1'
'ou =test 1'
'ou= test 1'
'ou=test 1 '
' ou = test 1 '
So are the following :
'ou=test 1+cn=test 2'
'ou = test 1 + cn = test 2'
' ou =test 1+ cn =test 2 '
'cn = test 2 +ou = test 1'
but the following are not equal :
'ou=test 1'
'ou=test 1'
because we have more than one spaces inside the value.
