Method Detail

getValues

List<Object> getValues(String attributeName)

Get all of the collected values for the specified attribute.

Get properly formatted attributes for use in the next query. The attribute names included will include Range specifiers as needed and only the attributes that have not been retrieved in full will be included.

Returns:

an array of Strings to be used as input to e.g. LdapTemplate.lookup(javax.naming.Name, String[], org.springframework.ldap.core.AttributesMapper) in the next iteration.

mapFromAttributes

T mapFromAttributes(Attributes attributes)
             throws NamingException

Goes through all of the attributes to record their values and figure out whether a new query iteration is needed to get more values.
