35 * @brief This class checks for equivalence between 2 instances of the %Float type.
39 * The %FloatComparer class checks for equivalence between 2 instances of the Float type.
41 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/collection_comparison.htm">Collection Comparisons</a>.
43 * The following example demonstrates how to use the %FloatComparer class.
49 * using namespace Tizen::Base;
52 * MyClass::FloatComparerSample(void)
56 * FloatComparer comparer;
58 * // Compares 2 instances of Float
60 * comparer.Compare(f1, f2, cmp);
68 class _OSP_EXPORT_ FloatComparer
70 , public Tizen::Base::Collection::IComparer
74 * This is the default constructor for this class.
81 * This destructor overrides Tizen::Base::Object::~Object().
85 virtual ~FloatComparer(void);
88 * Compares two given instances of type Float.
92 * @return An error code
93 * @param[in] obj1 The first instance of type Float
94 * @param[in] obj2 The second instance of type Float
95 * @param[out] cmp The result of comparison
96 * @exception E_SUCCESS The method is successful.
97 * @exception E_INVALID_ARG The specified object instances are not of the expected type.
98 * @remarks The value of @c cmp can be:
101 * < 0 if the value of @c obj1 is less than the value of @c obj2
102 * == 0 if the value of @c obj1 is equal to the value of @c obj2
103 * > 0 if the value of @c obj1 is greater than the value of @c obj2
