public class IterableResultSet
extends java.lang.Object
implements java.lang.Iterable<java.util.Map<java.lang.String,java.lang.Object>>

A simple wrapper that provides an Iterable implementation back-ended by a result-set. Allows a ResultSet to be used in a JDK 5.0 extended for-loop syntax. No result set can have more than one Iterable wrapper around it at a time. However, it is impossible for this object to know implicitly when it is no longer required (to free the reference). Therefore, when this wrapper is concluded, it should be disposed of via the dispose() method.
