    map method
    Перевод сравнение объектов методом MAP
    Описание Uses Oracle's ability to compare built-in types. E.g., you have defined an object type called rectangle, with attributes height and width. You can define a map method area that returns a number, namely the product of the rectangle's height and width attributes. Oracle can then compare two rectangles by comparing their areas. See comparison method.
