Detailed Description

A cursor-like interface that enforces a key range. The method signatures are actually those of SecondaryCursor, but the pKey parameter may be null. It was done this way to avoid doubling the number of methods.

This is not a general implementation of a range cursor and should not be used outside this package; however, it may evolve into a generally useful range cursor some day.
