All Implemented Interfaces:

ResultSetVisitor

public class IntResultSetAdapter

extends ResultSetAdapter

This class is a convenience result set adapter for when only one int value will be returned. Since there is no way to represent the equivalent of a null value for a primitive, an unset or error value will be represented by the infrequently used minimum integer value: Integer.MIN_VALUE.
