public interface StringValue extends Serializable
A simple converter to return a String representation of an object. This class is intended to be the "small coin" to configure/format textual cell content of concrete subclasses of ComponentProvider.

F.i. to show a Contributor cell object as "Busywoman, Herta" implement a custom StringValue and use it in a text rendering provider.


 StringValue stringValue = new StringValue() {
 
     public String getString(Object value) {
         if (!(value instanceof Contributor))
             return TO_STRING.getString(value);
         Contributor contributor = (Contributor) value;
         return contributor.lastName + ", " + contributor.firstName;
     }
 
 };
 
 ComponentProvider provider = new LabelProvider(stringValue);
 table.setDefaultRenderer(Contributor.class, 
   new DefaultTableRenderer(provider));
 

PENDING: use a full-fledged Format instead? Would impose a higher burden onto implementors but could be re-used in editors.
