public interface AdapterTemplateModel extends TemplateModel
TemplateModel
that can be unwrapped and then it considers a provided desired (hint) class. This is
useful when multiple languages has to communicate with each other through FreeMarker. For example, if we have a
model that wraps a Jython object, then we have to unwrap that differently when we pass it to plain Java method and
when we pass it to a Jython method.
This is rarely implemented by applications. It is typically implemented by the model classes belonging to
ObjectWrapper
-s.

getAdaptedObject(java.lang.Class hint)
Retrieves the underlying object, or some other object semantically
equivalent to its value narrowed by the class hint.

- the desired class of the returned value. An implementation
should make reasonable effort to retrieve an object of the requested
class, but if that is impossible, it must at least return the underlying
object as-is. As a minimal requirement, an implementation must always
return the exact underlying object when
hint.isInstance(underlyingObject) == true holds. When called
with java.lang.Object.class, it should return a generic Java
object (i.e. if the model is wrapping a scripting language object that is
further wrapping a Java object, the deepest underlying Java object should
be returned).
