Constructor Detail

DnComparator

public DnComparator(String oid)

Creates a new instance of DnComparator.

Parameters:

oid - The Comparator's OID

Method Detail

compare

public int compare(String dn1,
                   String dn2)

Compare two String DNs

Parameters:

dn1 - The first DN

dn2 - The second DN

Returns:

-1 i the first DN is inferior to the second DN, 1 if the second DN is superior, 0 of they are equal

compare

public int compare(Object obj0,
                   Object obj1)

getDn

private Dn getDn(Object obj)
          throws LdapInvalidDnException

Throws:

LdapInvalidDnException

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<Object>

Parameters:

schemaManager - the schemaManager to store
