void ColumnPartialCopyCmd::redo ( )

virtual

Execute the command.

void ColumnPartialCopyCmd::undo ( )

virtual

Undo the command.

Member Data Documentation

Column::Private* ColumnPartialCopyCmd::d_col

private

The private column data to modify.

Referenced by redo(), and undo().

Column::Private* ColumnPartialCopyCmd::d_col_backup

private

A backup of the orig. column.

Referenced by redo(), undo(), and ~ColumnPartialCopyCmd().

Column* ColumnPartialCopyCmd::d_col_backup_owner

private

A dummy owner for the backup column.

This is needed because a Column::Private must have an owner and we must have a Column::Private object as backup. Using a Column object as backup would lead to an inifinite loop.

Referenced by redo(), and ~ColumnPartialCopyCmd().

int ColumnPartialCopyCmd::d_dest_start

private

Start index in destination column.

Referenced by redo(), and undo().

int ColumnPartialCopyCmd::d_num_rows

private

Number of rows to copy.

Referenced by redo(), and undo().

int ColumnPartialCopyCmd::d_old_row_count

private

Previous number of rows in the destination column.

Referenced by redo(), and undo().

IntervalAttribute<bool> ColumnPartialCopyCmd::d_old_validity

private

The old validity information.

Referenced by redo(), and undo().

const AbstractColumn* ColumnPartialCopyCmd::d_src

private

The column to copy.

Referenced by redo().

Column::Private* ColumnPartialCopyCmd::d_src_backup

private

A backup of the source column.

Referenced by redo(), and ~ColumnPartialCopyCmd().

Column* ColumnPartialCopyCmd::d_src_backup_owner

private

A dummy owner for the source backup column.

This is needed because a Column::Private must have an owner and we must have a Column::Private object as backup. Using a Column object as backup would lead to an inifinite loop.
