37 * @brief This class checks for equivalence between 2 instances of the Float type.
41 * The %FloatComparer class checks for equivalence between 2 instances of the Float 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 %FloatComparer class.
51 * using namespace Tizen::Base;
54 * MyClass::FloatComparerSample(void)
58 * FloatComparer comparer;
60 * // Compares 2 instances of Float
62 * comparer.Compare(f1, f2, cmp);
70 class _OSP_EXPORT_ FloatComparer
72 , public Tizen::Base::Collection::IComparer
76 * This is the default constructor for this class.
83 * This destructor overrides Tizen::Base::Object::~Object().
87 virtual ~FloatComparer(void);
90 * Compares two given instances of type Float.
94 * @return An error code
95 * @param[in] obj1 The first instance of type Float
96 * @param[in] obj2 The second instance of type Float
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

113 * The implementation of this copy constructor is intentionally blank and declared as private to prohibit copying of objects.
