Constructor Detail

NormalizingComparator

public NormalizingComparator(String oid,
                             Normalizer normalizer,
                             LdapComparator<String> comparator)

A comparator which normalizes a value first before comparing them.

Parameters:

oid - The Comparator's OID

normalizer - the Normalizer to normalize values with before comparing

comparator - the underlying comparator to use for comparisons

Method Detail

compare

public int compare(String o1,
                   String o2)

setOid

public void setOid(String oid)

A special method used when renaming an SchemaObject: we may have to change it's OID This implementation makes sure we update the oid property of the contained normalizer and comparator.

Specified by:

setOid in interface SchemaObject

Overrides:

setOid in class AbstractSchemaObject

Parameters:

oid - The new OID

setOnServer

public void setOnServer()

tells that the normalizingComparator should not normalize values which are already normalized on the server
