Examples of gri.gridp.modules.Flag

gri.gridp.modules.Flag
A flag parameter which indicates a true or false value. A default value for the parameter can be specified as a boolean value. A text value will then be generated for this parameter depending on its value. An example would be a verbose flag which is "-v" when true and absent ("") when false. @author dan.rogers
