public class ObjectArrayWrapper

extends java.lang.Object

implements java.io.Serializable, java.lang.Comparable

This class is useful in picking up an object from the Hashtable where the key is an Object[]. Thus instead of putting Object[] as key just make ObjectArray class instance for that Object[] and use this as key so that different objects inside the Object[] with the same hashCodes when queried to Hashtable get its value object. This class overrides the equals(), hashCode() methods in java.lang.Object and implements the compareTo method from Comparable interface. Used in javax.management.TabularData class.
