/*| nsIMdbTableRowCursor: cursor class for iterating table rows
|
|
**|
|
|
**|| table: the cursor is associated with a specific table, which can be
|
|
**| set to a different table (which resets the position to -1 so the
|
|
**| next row acquired is the first in the table.
|
|
**|
|
|
**|| NextRowId: the rows in the table can be iterated by identity alone,
|
|
**| without actually reading the cells of any row with this method.
|
|
**|
|
|
**|| NextRowCells: read the next row in the table, but only read cells
|
|
**| from the table which are already present in the row (so no new cells
|
|
**| are added to the row, even if they are present in the table). All the
|
|
**| cells will have content specified, even it is the empty string. No
|
|
**| columns will be removed, even if missing from the row (because missing
|
|
**| and empty are semantically equivalent).
|
|
**|
|
|
**|| NextRowAllCells: read the next row in the table, and access all the
|
|
**| cells for this row in the table, adding any missing columns to the row
|
|
**| as needed until all cells are represented. All the
|
|
**| cells will have content specified, even it is the empty string. No
|
|
**| columns will be removed, even if missing from the row (because missing
|
|
**| and empty are semantically equivalent).
