+   * | accepted             | STRING   | No       | A regular expression in the set of characters to be accepted by the inputFilter (the default value is empty string) |
+   * | rejected             | STRING   | No       | A regular expression in the set of characters to be rejected by the inputFilter (the default value is empty string) |
+   *
+   * @note Optional.
+   * The character set must follow the regular expression rules.
+   * Behaviour can not be guaranteed for incorrect grammars.
+   * Refer the link below for detailed rules.
+   * The functions in std::regex library use the ECMAScript grammar:
+   * http://cplusplus.com/reference/regex/ECMAScript/
+   *
+   * You can use enums instead of "accepted" and "rejected" strings.
+   * @see Dali::Toolkit::InputFilter::Property::Type
+   *
+   * Example Usage:
+   * @code
+   *   Property::Map filter;
+   *   filter[InputFilter::Property::ACCEPTED] = "[\\d]"; // accept whole digits
+   *   filter[InputFilter::Property::REJECTED] = "[0-5]"; // reject 0, 1, 2, 3, 4, 5
+   *
+   *   editor.SetProperty(DevelTextEditor::Property::INPUT_FILTER, filter); // acceptable inputs are 6, 7, 8, 9
