37 * @brief This class is the @b root class of Tizen.
41 * The %Object class defines a set of behaviors and characteristics shared by all the other classes.
43 * The derived classes can override some of these methods, such as the Equals() method, which tests for object equivalence.
45 class _OSP_EXPORT_ Object
49 * This is the default constructor for this class.
56 * This is the destructor for this class.
60 virtual ~Object(void);
63 * Checks whether the value of the specified instance is equal to the value of the current instance of %Object.
67 * @return @c true if the value of the specified instance of %Object is equal to the value of the current instance of %Object, @n
69 * @param[in] obj An instance of %Object to compare
70 * @remarks The default implementation of this method returns @c true
71 * if the two instances have the same address. @n
72 * The method can be overridden to support value equality. Furthermore, this method must return the same result as the equality operator.
74 virtual bool Equals(const Object& obj) const;
77 * Gets the hash value of the current instance of %Object.
81 * @return An integer value indicating the hash value of the current instance of %Object
82 * @remarks Two equal instances must return the same hash value. For better performance,
83 * the used hash function must generate a random distribution for all inputs. @n
84 * The default implementation of this method returns the address of the current instance.
86 virtual int GetHashCode(void) const;
90 * This is the copy constructor for the %Object class.
92 * @param[in] obj An instance of %Object
94 Object(const Object& obj);
97 * Assigns the value of the specified instance to the current instance of %Object.
99 * @param[in] rhs An instance of %Object
101 Object& operator =(const Object& rhs);
104 // This method is for internal use only. Using this method can cause behavioral, security-related,
