35 * @brief This class is the wrapper class for the @c signed @c short built-in type.
39 * The %Short class represents an integer value ranging from -32768 to 32767. The class is useful when passing
40 * a 16-bit @c signed integral value to a method that accepts only an instance of Object. Furthermore,
41 * this class provides methods for converting a %Short (and @c short) to a String, and a %String to %Short
44 * The following example demonstrates how to use the %Short class.
50 * using namespace Tizen::Base;
52 * // This method checks whether the given string object contains a string
53 * // representation of the pre-defined minimum 16-bit integral value
55 * MyClass::Verify(String& string, bool& out)
57 * static const Short MINIMUM(1230);
59 * result r = E_SUCCESS;
62 * r = Short::Parse(string, s)
68 * out = (MINIMUM.Compare(s) == 0) ? true: false;
76 class _OSP_EXPORT_ Short
81 * Initializes this instance of %Short with the specified @c value.
85 * @param[in] value A @c short value
87 Short(short value = 0);
90 * This is the copy constructor for the %Short class.
94 * @param[in] value An instance of %Short
96 Short(const Short& value);
99 * This is the destructor for this class.
103 virtual ~Short(void);
106 * Assigns the value of the specified instance to the current instance of %Short.
110 * @param[in] rhs An instance of %Short
112 Short& operator =(const Short& rhs);
115 * Compares the specified @c short values.
119 * @return A 32-bit @c signed @c integer value
120 * @param[in] s1 The first @c short value to compare
121 * @param[in] s2 The second @c short value to compare
124 * < 0 if @c s1 is less than @c s2
125 * == 0 if @c s1 is equal to @c s2
126 * > 0 if @c s1 is greater than @c s2
129 static int Compare(short s1, short s2);
132 * Compares the value of the current instance of the %Short class
133 * with the value of the specified instance of the %Short class.
137 * @return A @c signed 32-bit @c integer value
138 * @param[in] value An instance of the %Short class to compare
141 * < 0 if the value of the current instance is less than that of the specified instance
142 * == 0 if the value of the current instance is equal to that of the specified instance
