All, I'm interested in writing a custom iterator, and I've been looking for documentation on how to do so. Thus far, I've not been able to find anything beyond the java docs in SortedKeyValueIterator and a few other sub-classes. A few of the examples use Iterators, but provide no real info on how to properly implement one. Is there anywhere to find general guidance on the iterator stack?
(If you're interested) Specifically, for those that are curious, I'm trying to implement something similar to the wikisearch example, but with some key differences. In my case, I've got a file with various attributes that being indexed. So for each file there are 5 attributes, and each attribute has a fixed number of possible values. For example (totally made up): personID, gender, hair color, country, race, personRecord Row:binID; ColFam:Attribute_AttributeValue; ColQ:PersonID; Val:blank AND Row:binID; ColFam:"D"; ColQ:personID; value:personRecord A typical query would be: Give me the personRecord for all people with: Gender: male & Hair color: blond or brown & Country: USA or England or china or korea & Race: white or oriental The existing Iterators used in the wikisearch example are unable to handle the "or" clauses in each attribute. The OrIterator doesn't appear to handle the possibility more than one row per tablet Thanks, Tejay Cardon
