    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

  - 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
