All Implemented Interfaces:

Serializable, Comparator<String>, SchemaObject

public class UniqueMemberComparator
extends LdapComparator<String>

A comparator that sorts OIDs based on their numeric id value. Needs a OidRegistry to properly do it's job. Public method to set the oid registry will be used by the server after instantiation in deserialization.

Constructor Detail

UniqueMemberComparator

public UniqueMemberComparator(String oid)

The IntegerComparator constructor. Its OID is the IntegerOrderingMatch matching rule OID.

Parameters:

oid - The Comparator's OID

Method Detail

compare

public int compare(String dnstr1,
                   String dnstr2)

setSchemaManager

public void setSchemaManager(SchemaManager schemaManager)

Store the SchemaManager in this instance. It may be necessary for some comparator which needs to have access to the oidNormalizer Map.

Overrides:

setSchemaManager in class LdapComparator<String>

Parameters:

schemaManager - the schemaManager to store

getDn

public Dn getDn(Object obj)
         throws LdapInvalidDnException

Get the DN from the given object

Parameters:

obj - The object containing a DN (either as an instance of Dn or as a String)

Returns:

A Dn instance

Throws:

LdapInvalidDnException - If the Dn is invalid
