Method Summary

Modifier and Type	Method	Description
protected void	clearAttributeList(int cnt)	Method called by native library to empty the Attribute list, and insert a number of null place-holders
boolean	equals(Object anObject)	Compare this RDN to the specified object, and return true if the argument is a RDN that represents the same value as this object.
protected void	finalize()	Releases any native structures associated with this object.
Attribute	getAttribute(int pos)	Returns an attribute from the RDN.
int	getAttributeCount()	Returns the number of attributes.
int	hashCode()	Overrides Object.hashCode in order to be consistent with the equals(Object) method.
boolean	isSameValue(RDN value)	Test whether this value is equivalent to another.
Iterator<Attribute>	iterator()	Iterate through all the Attributes in this RDN.
protected void	jni_dispose()	Native function used to clean up any C data structures attached to this object when it is destroyed in finalisation.
String	toOIDString()	Generate a String representation of the RDN, including dotted OID values instead of attribute names.
final String	toString()	Returns a String representation of the RDN, containing its attribute name(s) and value(s).
final String	toUIString()	Return a friendly string representation of the RDN (in other words, one that contains no attribute type names).

Constructor Details

RDN

public RDN(String rdnStr)
    throws BadDNException

Constructs an RDN from LDAP formatted string.

Parameters:

rdnStr - String representation of RDN (not null).

Throws:

BadDNException - in case of invalid RDN.

NativeLibraryException - if an unrecoverable error was detected by the native library

RDN

public RDN(Attribute... attrs)
    throws BadDNException

Constructs a new object based on a list of Attributes.

Parameters:

attrs - list of Attributes (not null)

Throws:

BadDNException - in case of invalid RDN, or if attrs is null.

NativeLibraryException - if an unrecoverable error was detected by the native library

RDN

public RDN(AttributeType attrType,
 String value)
    throws BadDNException,
BadSyntaxException,
BadValueException

Constructs an RDN based on a single attribute value. For example:

   AttributeType snType = new AttributeType("sn");
   RDN rdn = new RDN(snType, "Smith");

will create an RDN for "sn=Smith"

Parameters:

attrType - an AttributeType (not null)

value - attribute value string (not null)

Throws:

BadDNException - in case of invalid RDN.

BadSyntaxException - if the syntax of value is not valid for this attribute.

BadValueException - if value is not a valid LDAP string representation of an attrType.

NativeLibraryException - if an unrecoverable error was detected by the native library.

Since:

16.0

Method Details

jni_dispose

protected void jni_dispose()
                    throws NativeLibraryException

Native function used to clean up any C data structures attached to this object when it is destroyed in finalisation.

Throws:

NativeLibraryException - if an unrecoverable error was detected by the native library

finalize

protected void finalize()
                 throws Throwable

Releases any native structures associated with this object.

Overrides:

finalize in class Object

Throws:

Throwable

clearAttributeList

protected void clearAttributeList(int cnt)

Method called by native library to empty the Attribute list, and insert a number of null place-holders

getAttributeCount

public int getAttributeCount()

Returns the number of attributes.

Returns:

the number of Attributes

getAttribute

public Attribute getAttribute(int pos)

Returns an attribute from the RDN.

Parameters:

pos - Position in (unordered) list of RDNs.

Returns:

RDN at given position (not null).

Throws:

ArrayIndexOutOfBoundsException - if pos out of range.

iterator

public Iterator<Attribute> iterator()

Iterate through all the Attributes in this RDN.

Specified by:

iterator in interface Iterable<Attribute>

isSameValue

public boolean isSameValue(RDN value)
                    throws NativeLibraryException,
NullPointerException

Test whether this value is equivalent to another.

Parameters:

value - Value to compare against (not null)

Returns:

true if the given object represents the same value as this one, false otherwise.

Throws:

NativeLibraryException - if an unrecoverable error was detected by the native library

NullPointerException

toUIString

public final String toUIString()

Return a friendly string representation of the RDN (in other words, one that contains no attribute type names).

Thus an RDN of "cn=Mister Magoo" gives "Mister Magoo".

Multiple values are separated by non-delimited plus signs, for example "sales+J. Smith". Unlike the toString() method, no escaping of special characters within the values takes place; so an RDN representing the common name "harry, fred, ginger + marty" will be returned as "harry, fred, ginger + marty".

Returns:

"UI-friendly" string representation of RDN (not null)

See Also:

• toString()

toString

public final String toString()
                      throws NativeLibraryException

Returns a String representation of the RDN, containing its attribute name(s) and value(s). Multiple values are separated by non-delimited plus signs, for example "ou=sales+cn=J. Smith". Any special characters within the attribute values will be escaped with a "\". For example an RDN representing a common name of "harry, fred, ginger + marty" will be returned as "cn=harry\, fred\, ginger \+ marty". The String returned is suitable for using in the RDN(String) constructor.

Overrides:

toString in class Object

Returns:

String representation of RDN (not null)

Throws:

NativeLibraryException - if an unrecoverable error was detected by the native library

See Also:

• RDN(String)
• toUIString()
• toOIDString()

equals

public boolean equals(Object anObject)

Compare this RDN to the specified object, and return true if the argument is a RDN that represents the same value as this object.

Overrides:

equals in class Object

Parameters:

anObject - an object to compare this RDN against (null allowed - will return false)

Returns:

true if the values are equal, false otherwise.

Throws:

NativeLibraryException - if an unrecoverable error was detected by the native library

hashCode

public int hashCode()

Overrides Object.hashCode in order to be consistent with the equals(Object) method.

Overrides:

hashCode in class Object

toOIDString

public String toOIDString()

Generate a String representation of the RDN, including dotted OID values instead of attribute names.

String values returned by this method may be used when constructing new RDNs, in which case they are considered equivalent to their "non OID" forms.

For example

     RDN rdn = new RDN("cn=Mister Magoo");
     String str = rdn.toString();
     String oid = rdn.toOIDString();
     System.out.println(str);
     System.out.println(oid);
     RDN rdn2 = new RDN(oid);
     System.out.println(rdn.equals(rdn2));
 

will display

   cn=Mister Magoo
   2.5.4.3=Mister Magoo
   true
 

Returns:

a String representation with OIDs being used for attribute names

14.6
