Poor feature set of xsruntime.db.ResultSet

Hi there,

it seems the xsruntime.db.ResultSet offers very little functionality for navigating thourgh the record set.

There's just a next() method - that's all.

I would expect some standard-features like "next(), last(), previous(), first(), isLast(), isFirst(), getRecordCount()" and so on for the ease of use of the resultset.

Do I miss something, or maybe I'm using a deprecated reference?
