Examples of InspectableObject

org.apache.hadoop.hive.serde2.objectinspector.InspectableObject
Simple wrapper of object with ObjectInspector. TODO: we need to redefine the hashCode and equals methods, so that it can be put into a HashMap as a key. This class also serves as a facility for a function that returns both an object and an ObjectInspector.
