Objekt TKAPMemTable

Tato třída slouží pro manipulaci s paměťovými tabulkami. Jedná se jen o dočasné tabulky, které po uvolnění z paměti přestanou existovat. Je možné vytvožit tabulku, definovat pole tabulky či indexy, otevřít tabulku, procházet záznamy tabulky, filtrovat záznamy, načítat či měnit hodnoty z jednotlivých polí záznamu apod.
