+ * @class ImmutableString
+ * @brief This class represents a immutable sequence of Unicode characters.
+ *
+ * @since 3.0
+ *
+ * The %ImmutableString class represents a immutable sequence of Unicode characters.
+ * Mutation operation, such as Append(), Insert() and Remove(), do not change the current instance but return a new instance resulting from applying the operation.
+ *
+ * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/immutablestring.htm">ImmutableString</a>.
+ *
+ * The following example demonstrates how to use the %ImmutableString class.
+ *
+ * @code
+ *
+ * #include <FBase.h>
+ *
+ * using namespace Tizen::Base;
+ *
+ * void
+ * MyClass::ImmutableStringSample(void)
+ * {
+ * ImmutableString str(L"Test"); // str == L"Test"
+ *
+ * ImmutableString str1 = str.Append(L"String"); // str1 == L"TestString"
+ *
+ * ImmutableString str2 = str1.Insert(L"Immutable", 4); // str2 == L"TestImmutableString"
+ *
+ * ImmutableString str3 = str2.Remove(4, 5); // str3 == L"TestableString"
+ *
+ * ImmutableString str4 = str3.SubString(4, 4); // str4 == L"able"
