Table class. enables to define a table, to insert, update or delete records, to iterate trough the table, to search appropriate records by the value in the specified field.Description: This file contains the Table class which enables persistent "table-like" storage of information with sequential access only. ATTENTION:
Methods First, Next, FindFirst, FindNext return NEW INSTANCE of class Record. Therefore every object returned by these should be disposed off. Table takes no responsibility for freeing searchValue (used in FindFirst and FindNext methods) because searching e.g. for an integer is simply done this way: Int searchFor = 100; Record *r = table->FindFirst("Integer field", searchFor);In such a case there would be no sense to free searchFor, even more it would be a mistake.Remember that changing contents of memory pointed to by searchValue means searching for new value (FindFirst doesn't create its own copy of *searchValue - it cannot, because it would have to know how many bytes it should copy. That seemed ugly to me.).
