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
