To utilize ThreadDB in your application it is first necessary to identify the type of data which should be stored. In general one has to separate between fixed and variable length data items. For fixed length item data no additional information is required. This follows the general principle of the std:: template containers. Since the size of stored data items is not stored in the database itself, variable length data requires intrusive handling of the item size. This could be achieved by either an unique identifier to distinguish different types of data or by a class member providing the item size directly. In both cases usually two read steps are required. In the first step the length (or type) information of the data item is read and in a 2nd step the data section of the stored item.
