36 * @brief This class checks for equivalence between 2 instances of the %Long type.
40 * The %LongComparer class checks for equivalence between 2 instances of the Long type.
42 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/collection_comparison.htm">Collection Comparisons</a>.
44 * The following example demonstrates how to use the %LongComparer class.
50 * using namespace Tizen::Base;
53 * MyClass::LongComparerSample(void)
57 * LongComparer comparer;
60 * comparer.Compare(l1, l2, cmp);
68 class _OSP_EXPORT_ LongComparer
70 , public virtual Tizen::Base::Collection::IComparer
74 * This is the default constructor for this class.
81 * This destructor overrides Tizen::Base::Object::~Object().
85 virtual ~LongComparer(void);
88 * Compares two given instances of type Long.
92 * @return An error code
93 * @param[in] obj1 The first instance of type %Long
94 * @param[in] obj2 The second instance of type %Long
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
106 virtual result Compare(const Tizen::Base::Object& obj1, const Tizen::Base::Object& obj2, int& cmp) const;
111 * The implementation of this copy constructor is intentionally blank and declared as private to prohibit copying of objects.
113 LongComparer(const LongComparer& obj);
116 * The implementation of this copy assignment operator is intentionally blank and declared as private to prohibit copying of objects.
