public class StringConverter

extends java.lang.Object

Converts a String into a given object type (and back again). Supports factories, so if you have a custom type, you can add it, e.g.

        stringconverter.setFactory(Foo.class,
                new StringConverter.Factory() {
                     public Object fromString(String value) {
                         return new Foo(value);
                     }
                     public String toString(Object obj) {
                         return ((Foo)obj).getStringValue();
                     }
                 });
