35 * @brief This class represents a key-value pair.
39 * The %MapEntry class represents a key-value pair.

43 class _OSP_EXPORT_ MapEntry
48 * This is the default constructor for this class.
52 * @param[in] key The key
53 * @param[in] value The value
55 MapEntry(const Object& key, const Object& value);
58 * This destructor overrides Tizen::Base::Object::~Object().
62 virtual ~MapEntry(void);
65 * Gets the key corresponding to this entry.
69 * @return The key corresponding to this entry
72 virtual const Object* GetKey(void) const;
75 * Gets the value corresponding to this entry.
79 * @return The value corresponding to this entry
82 virtual const Object* GetValue(void) const;
85 * Gets the key corresponding to this entry.
89 * @return The key corresponding to this entry
92 virtual Object* GetKey(void);
95 * Gets the value corresponding to this entry.
99 * @return The value corresponding to this entry
102 virtual Object* GetValue(void);
105 * Compares the value of the given Object to the
106 * value of the calling object.
110 * @return @c true if the values are equal, @n
112 * @param[in] obj The object to compare with the calling object
113 * @remarks Returns @c false if the given object is not a %MapEntry object.
115 virtual bool Equals(const Object& obj) const;
118 * Gets the hash value of the current instance.
122 * @return The hash value of the current instance
123 * @remarks The two Tizen::Base::Object::Equals() instances must return the same hash value. For better performance, @n
124 * the used hash function must generate a random distribution for all inputs.
126 virtual int GetHashCode(void) const;
130 * This is the default constructor for this class.
140 * This is the copy constructor for this class.
142 * @param[in] entry The instance of the MapEntry class to copy from
144 MapEntry(const MapEntry& entry);
147 * Assigns the value of the specified instance to the current instance of %MapEntry.
149 * @param[in] entry An instance of %MapEntry
