This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.
Get the SDO_Model_Property that contains the SDO_DataObject. This method is used to navigate up to the parent's property which contains the data object which has been reflected upon.
Returns the container's SDO_Model_Property which references the SDO_DataObject, or
NULL if it is a root SDO_DataObject.
