/** \class AutoPointerDataObjectDecorator
* \brief Decorates any pointer to a simple object with a DataObject API using
* AutoPointer semantics.
*
* AutoPointerDataObjectDecorator decorates a pointer to an object
* with a DataObject API. This allows a pointer to an object to be
* encapsulated in a DataObject and passed through the pipeline. This
* object differs from SimpleDataObjectDecorator in that the decorator
* takes control of deleting the pointer upon destruction.
*
* The decorator provides two methods Set() and Get() to access the
* decorated object (referred internally as the component).
*
* Note that when an instance of SimpleDataObjectDecorator is created,
* the component is initialized with its default constructor (i.e. a
* null pointer).
