* works the same way, but gets its values from the cache when it can.
* if no ids were passed in, that means they want the complete list.
* hopefully most of the time the calling app will specify which ids they are looking for.
* much more efficient that way.
* if no ids passed in and we get a cache miss, we gotta get all the keys again.
* might as well get the data too. when repopulating the row-wise cache, be careful not to
* clobber data that was populated by add or subtract calls. only populate if missing.
* use cache add approach ... much cleaner ... avoids race condition where
* db updates at the same time some other process loads and accidentally
* clobbers the value from the write.
* if the refresh flag was set for this object, go ahead and overwrite anything in the cache.
* this should only be used when debugging. not useful on production, and a little dangerous.
* this method uses cache callback to do row-wise caching.
* it uses the ids supplied as the keys, or if none supplied, the index that also lives in the cache.
