Notes

Things in need of re-examination:

  • interface ifSingleKeyedRow
  • Standard storage-PortalRow class expects the Table to have the table name (via tTableSource, but other constructions are possible.

rearrangement in progress

Core functionality:

  • handle current row - cFieldRow
  • handle multiple rows
    • sequential - tSequentialAccess
      • status (how many rows found)
      • position row cursor
      • access current row
      • end-of-rowset flag
    • indexed

Database sources:

  • manage what's in the source (selected, sequential access)

Currently, Table (Source) objects define:
