Member Function Documentation

virtual string Table::Cursor::as_string (   )  const [virtual]

String representation of this cursor. Reimplemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.

virtual bool Table::Cursor::avail (   )  const [pure virtual]

Return true iff row_data will return data for a valid row. Implemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.

virtual void Table::Cursor::deleteRow (   )  const [pure virtual]

Delete the current row from the database. Valid only if avail(). Implemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.

virtual Cursor& Table::Cursor::operator++ (   )  [pure virtual]

Move forward to the next row. Implemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.

virtual void Table::Cursor::reset (   )  [pure virtual]

Point the cursor at the first valid row. This will need to be called before the cursor is valid after construction. Implemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.

virtual const char* Table::Cursor::rowData (   )  const [pure virtual]

Returns a pointer to the data of the current row. Valid only if avail(). Implemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.

virtual void Table::Cursor::setTuple (  const char *  tuple  )  [pure virtual]

Set the input tuple in this cursors internal context. Must be called before reset, if the cursor is going to use data from the input tuple. Implemented in TableScanCursor, KeyEqualCursor, and IndexKeyEqualCursor.
