Examples of org.apache.turbine.util.db.Criteria

org.apache.turbine.util.db.Criteria
This is a utility class that is used for retrieving different types of values from a hashtable based on a simple name string. This class is meant to minimize the amount of casting that needs to be done when working with Hashtables. NOTE: other methods will be added as needed and as time permits. @author Frank Y.
