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.
