39 * @brief This class checks for equivalence between 2 instances of the String type.
43 * The %StringComparer class checks for equivalence between 2 instances of the String type.
45 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/collection_comparison.htm">Collection Comparisons</a>.
47 * The following example demonstrates how to use the %StringComparer class.
53 * using namespace Tizen::Base;
56 * MyClass::StringComparerSample(void)
60 * StringComparer strComparer;
63 * strComparer.Compare(s1, s2, cmp);
71 class _OSP_EXPORT_ StringComparer
73 , public virtual Tizen::Base::Collection::IComparer
77 * This is the default constructor for this class.
84 * This destructor overrides Tizen::Base::Object::~Object().
88 virtual ~StringComparer(void);
91 * Compares two given instances of type String.
95 * @return An error code
96 * @param[in] obj1 An object of String to compare
97 * @param[in] obj2 An object of String to compare
98 * @param[out] cmp The result of comparison
99 * @exception E_SUCCESS The method is successful.
100 * @exception E_INVALID_ARG The specified object instances are not of the expected type.
101 * @remarks The value of @c cmp can be:
104 * < 0 if the value of @c obj1 is less than the value of @c obj2
105 * == 0 if the value of @c obj1 is equal to the value of @c obj2
106 * > 0 if the value of @c obj1 is greater than the value of @c obj2
109 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.
115 StringComparer(const StringComparer& obj);
118 * The implementation of this copy assignment operator is intentionally blank and declared as private to prohibit copying of objects.
