AbstractContextMapper class and ParameterizedContextMapper interface

[erjablow]

These two items seem to be at cross purposes. AbstractContextMapper has subclasses implement

protected abstract Object doMapFromContext(DirContextOperations ctx)

The mapFromContext method is final, and returns Object.

The ParameterizedContextMapper<T> interface includes

T mapFromContext(Object ctx)

One cannot mix these two; the following declaration does not compile:

public class PersonContextMapper extends AbstractContextMapper
    implements ParameterizedContextMapper<Person>

Would it be possible to combine the ideas of these two items? Could there be a ParameterizedAbstractContextMapper<T>:

public abstract class ParameterizedAbstractContextMapper<T>
    implements ParameterizedContextMapper<T> {
    public final T mapFromContext(Object obj) {
        return doMapFromContext((DirContextOperations) obj);
    }
    protected abstract T doMapFromContext(DirContextOperations ctx);
}

I think you're looiking for AbstractParameterizedContextMapper<T>, right?

I apologize. I really should look harder at the Javadoc. Darn!
