public abstract class SlingAdaptable extends Object implements Adaptable
SlingAdaptable
class is an (abstract) default implementation
of the Adaptable
interface. It just uses the default
AdapterManager
implemented to adapt itself to the requested type.
Extensions of this class may overwrite the adaptTo(Class)
method
using their own knowledge of adapters and should call this base class
implementation to fall back for other types.
