public interface StringValue
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.
