cox.jmatt.java.MathTools.demo.PizzaPanel
public class PizzaPanel
This class provides an easy way to specifiy polymorphic configurable parameters to test MathTools (or other class) methods. The parameters in the TextArea can be edited to appropriate values. The program can then call an appropriate 'as__(N) method to retrieve the parameter. The value N is the index of the parameter to fetch. Example: asLong(4) fetches 'par.4=...' as a long.
This class may be used as-is to supply parameters to another class or it may be extended. The processGoButton() is the extension method. The default implementation merely eats the pizza (Properties) in the TextArea. The getNorthPanel() method provides a quick and easy way to provide a simple GUI.
NOTE: The eatPizza() method MUST be called before meaningful values can be extracted from the parameters. The default values for all as__() methods are:
0 for numeric methods, '' for String, null for asNullString()
and false for boolean.
