http://jdbi.org/: jDBI is designed to provide convenient tabular data access in Java(tm). It uses the Java collections framework for query results, provides a convenient means of externalizing sql statements, and provides named parameter support for any database being used.

Represents a forward-only iterator over a result set, which will lazily iterate
the results. The underlying ResultSet can be closed by calling the close() method. 

The default implementation of ResultIterator will automatically close
the result set after the last element has been retrieved via next() and
hasNext() is called (which will return false). This allows for iteration
over the results with automagic resource cleanup.


The remove() operation is not supported in the default
version, and will raise an UnsupportedOperationException
