Constructor Detail

### RowManagerImpl

    public RowManagerImpl(boolean order)

  Constructor.

  Parameters:
    `order` - whether to keep track of the order in which rows are added

Method Detail

### hasAutoAssignConstraints

    public boolean hasAutoAssignConstraints()

  Whether any primary rows have auto-assign constraints.

### getOrdered

    public List<PrimaryRow> getOrdered()

  Return the ordered primary rows. Only available if ordering requested on construction.

### getInserts

    public Collection<PrimaryRow> getInserts()

  Return all inserted primary rows.

### getUpdates

    public Collection<PrimaryRow> getUpdates()

  Return all updated primary rows.

### getDeletes

    public Collection<PrimaryRow> getDeletes()

  Return all deleted primary rows.

### getSecondaryUpdates

    public Collection<SecondaryRow> getSecondaryUpdates()

  Return all inserted and updated secondary rows.

### getSecondaryDeletes

    public Collection<SecondaryRow> getSecondaryDeletes()

  Return all deleted secondary rows.

### getAllRowUpdates

    public Collection<Row> getAllRowUpdates()

  Return any 'all row' updates.

### getAllRowDeletes

    public Collection<Row> getAllRowDeletes()

  Return any 'all row' deletes.

### getSecondaryRow

    public Row getSecondaryRow(Table table,
                               int action)

  Description copied from interface: `RowManager`
  Return a row for the given secondary table. The action must be one of `Row.ACTION_INSERT`, `Row.ACTION_UPDATE`, `Row.ACTION_DELETE`. Note that secondary rows are not considered when creating the foreign key dependency graph, with can cause constraint violations when using the `UPDATE` action. Only use this action if the secondary row does not have restrict-action foreign keys. Otherwise use both a delete and then an insert to perform the update.

  Specified by:
    `getSecondaryRow` in interface `RowManager`

### flushSecondaryRow

    public void flushSecondaryRow(Row row)
                           throws SQLException
