Constructor and Description
NormalizingComparator(String oid, Normalizer normalizer, LdapComparator<String> comparator) A comparator which normalizes a value first before comparing them.

Method Summary

Modifier and Type	Method and Description
int	compare(String o1, String o2) If any normalization attempt fails we compare using the unnormalized object.
void	setOid(String oid) A special method used when renaming an SchemaObject: we may have to change it's OID
void	setOnServer() tells that the normalizingComparator should not normalize values which are already normalized on the server

Constructor Detail

NormalizingComparator

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

A comparator which normalizes a value first before comparing them.

Parameters:

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)

If any normalization attempt fails we compare using the unnormalized object.

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
