What I was looking for (stream of values):
{code:java}
StreamSupport.stream(attribute.spliterator(), false)
{code}
{code:java}
Set<Dn> m = entry.getAttributes().stream()
.filter(x -> group_fields.contains(x.getUpId()) )
.flatMap(y -> StreamSupport.stream(y.spliterator(), false) )
.map(c -> c.getString())
.map(z -> LDAPUtil.getDn(z))
.collect(Collectors.toSet());
{code}
BTW, your example works. The same way as my first example, except I used
{code:java}
attribute.forEach(...)
{code}

> add stream convenient methods to class Attribute
> ------------------------------------------------
>
> Key: DIRAPI-360
> URL: https://issues.apache.org/jira/browse/DIRAPI-360
> Project: Directory Client API
> Issue Type: Improvement
> Affects Versions: 2.0.1
> Reporter: Darth Bolek
> Priority: Trivial
>
> When attribute has multiple values (groupOfUniqueNames -> uniqueMember) there
> is no stream convenient way of processing all of the values.
>
> what to do:
> add methods to class: org.apache.directory.api.ldap.model.entry.Attribute
> Collection<String> getStringValues()
> possibly also other methods with other/generic data types.
>
> example:
> Before (that is right now):
>
> {code:java}
> Set<Dn> m = entry.getAttributes().stream()
> .filter(x -> group_fields.contains(x.getUpId()) )
> .flatMap(y -> {
> Set<String> tmpSet = new HashSet<String>();
> y.forEach(z -> tmpSet.add(z.getString()));
> return tmpSet.stream();
> } )
> .map(z -> LDAPUtil.getDn(z))
> .collect(Collectors.toSet());
> {code}
>
> After:
> {code:java}
> Set<Dn> m = entry.getAttributes().stream()
> .filter(x -> group_fields.contains(x.getUpId()) )
> .flatMap(y -> y.getStringValues().stream() )
> .map(z -> LDAPUtil.getDn(z))
> .collect(Collectors.toSet());
> {code}
