Unreadable code example

Sometimes you meet code like this.
I don't understand even a snippet.

public class LinesJournalist extends Journalist {
    private final LinesLiner _liner;

 public LinesJournalist(LinesLiner liner) {
            _liner = liner;
 }

 @Override
 public AbstractMessage createMessageFrom(MessageFactory aMessageFactory, Fields anInput) {
     // THINK: e' sospetto che per association liner non posso passare NullLiner...
     LinesConfigurableLiner associationLiner = new LinesConfigurableLiner("", false, false);
     LinesConfigurableLiner valuesLiner = new LinesConfigurableLiner("", false, false);
            Lines lines = anInput.asLines(new FieldsSimpleLiner(new LinkSimpleLiner(associationLiner, new LinesEmptyLiner(), valuesLiner)));
            Fields fields = Fields.single(AbstractMessage.MESSAGE, lines.asLines(_liner).report());
            return aMessageFactory.make(fields);
 }
}
