JarCasting
Goal
Define converters (static method or not) then be able to use them for single object or collections through ObjectConverter interface.
Example
public static class LenConverter {
// static method
@Converter(in = In.class, out = Out.class)
public static Out convert(final In in) {
return new Out(in.value.length());
}
// or use completely CDI
@Inject
private Helper helper;
@Converter(in = String.class, out = String.class)
public String convert(final String in) {
return helper.foo(in);
}
}
then in another bean:
@Inject
@Converter(in = In.class, out = Out.class)
private ObjectConverter<In, Out> len;
// ...
assertEquals(3, len.to(new In("foo")).len);
