36 * @brief This class is the root class of %Tizen.
40 * The %Object class defines a set of behaviors and characteristics shared by all the other classes.
42 * The derived classes can override some of these methods, such as the Equals() method, which tests for object equivalence.
44 class _OSP_EXPORT_ Object
48 * This is the default constructor for this class.
55 * This is the destructor for this class.
59 virtual ~Object(void);
62 * Checks whether the value of the specified instance is equal to the value of the current instance of %Object.
66 * @return @c true if the value of the specified instance of %Object is equal to the value of the current instance of %Object, @n
68 * @param[in] obj An instance of %Object to compare
69 * @remarks The default implementation of this method returns @c true
70 * if the two instances have the same address. @n
71 * The method can be overridden to support value equality. Furthermore, this method must return the same result as the equality operator.
73 virtual bool Equals(const Object& obj) const;
76 * Gets the hash value of the current instance of %Object.
80 * @return An integer value indicating the hash value of the current instance of %Object
81 * @remarks Two equal instances must return the same hash value. For better performance,
82 * the used hash function must generate a random distribution for all inputs. @n
83 * The default implementation of this method returns the address of the current instance.
85 virtual int GetHashCode(void) const;
89 * This is the copy constructor for the %Object class.
91 * @param[in] obj An instance of %Object
93 Object(const Object& obj);
96 * Assigns the value of the specified instance to the current instance of %Object.
98 * @param[in] rhs An instance of %Object
100 Object& operator =(const Object& rhs);
103 // This method is for internal use only. Using this method can cause behavioral, security-related,
104 // and consistency-related issues in the application.
