Examples of org.apache.empire.commons.Options

org.apache.empire.commons.Options
This class represents a list of possible values that are valid for a particular field.
Additionally the class provides a text string describing the value for display purposes.
The class is implemented as a set of OptionEntry objects where the entry value is used as the key for the set and thus must be unique.

     * @return an Options object containing a set a of values and their corresponding names
