About

Each PortCard represents a single row of data in a particular format. The standard base formats (which correspond those used by PortRows) are:

• Native (calc), which is used only for internal calculations (no I/O)
• Storage (stor): I/O Row which converts to and from SQL (or, in theory, any other database-storage format)
• Display (disp): I/O Row which converts to and from HTML (or, in theory, any other display markup)

Once loaded with data from a given Row, a PortCard is never re-loaded with data from a different row; it always corresponds to the same row, although individual fields may be modified for output purposes. Loading a new row into a Card requires creating a new Card.

Key Methods

• caPortIORow::TransloadInput() : tell I/O row to convert its data to native format and load to calc row
• caPortIORow::TransloadOutput() : tell I/O row to convert data in calc row to native and load to itself
• data\rows\tDBAccess::GetMySpec() : data\spec\cQuery : fetches a Storage Card's Spec object for access to data operations
• data\spec\cTable::Table(data\rows\cStor $o = NULL) : data\cTabloid : fetches the Table object specified by the Spec
• data\tUpdatable::DoUpdate(array $arChg, string $sqlWhere) : cUpdateStatus : updates the changed fields (specified in $arChg) for rows specified by $sqlWhere in the current table in the database
