37 * @brief This class checks for equivalence between 2 instances of the Double type.
41 * The %DoubleComparer class checks for equivalence between 2 instances of the Double type.
43 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/collection_comparison.htm">Collection Comparisons</a>.
45 * The following example demonstrates how to use the %DoubleComparer class.
51 * using namespace Tizen::Base;
54 * MyClass::DoubleComparerSample(void)
58 * DoubleComparer comparer;
60 * // Compare 2 instances of Double
62 * comparer.Compare(d1, d2, cmp);
70 class _OSP_EXPORT_ DoubleComparer
72 , public virtual Tizen::Base::Collection::IComparer
76 * This is the default constructor for this class.
83 * This destructor overrides Tizen::Base::Object::~Object().
87 virtual ~DoubleComparer(void);
90 * Compares two given instances of type Double.
94 * @return An error code
95 * @param[in] obj1 The first instance of type %Double
96 * @param[in] obj2 The second instance of type %Double
97 * @param[out] cmp The result of comparison
98 * @exception E_SUCCESS The method is successful.
99 * @exception E_INVALID_ARG The specified object instances are not of the expected type.
100 * @remarks The value of @c cmp can be:
103 * < 0 if the value of @c obj1 is less than the value of @c obj2
104 * == 0 if the value of @c obj1 is equal to the value of @c obj2
105 * > 0 if the value of @c obj1 is greater than the value of @c obj2
108 virtual result Compare(const Tizen::Base::Object& obj1, const Tizen::Base::Object& obj2, int& cmp) const;
113 * The implementation of this copy constructor is intentionally blank and declared as private to prohibit copying of objects.
