All Known Implementing Classes:

InsertResultSet
```
public interface TargetResultSet
extends ResultSet
```
The TargetResultSet interface is used to provide additional operations on result sets that are the target of a bulk insert or update. This is useful because bulk insert is upside down - the insert is done via the store.

- Method Detail
  - changedRow
```
void changedRow(ExecRow execRow,
                RowLocation rowLocation)
         throws StandardException
```
    Pass a changed row and the row location for that row to the target result set.
    
    Parameters:
    
    execRow - The changed row.
    
    rowLocation - The row location of the row.
    
    Throws:
    
    StandardException - thrown if cursor finished.
  - offendingRowLocation
```
void offendingRowLocation(RowLocation rl,
                          long constainerId)
                   throws StandardException
```
    Throws:
    
    StandardException
  - preprocessSourceRow
```
ExecRow preprocessSourceRow(ExecRow sourceRow)
                     throws StandardException
```
    Preprocess the source row prior to getting it back from the source. This is useful for bulk insert where the store stands between the target and the source.
    
    Parameters:
    
    sourceRow - The source row.
    
    Returns:
    
    The preprocessed source row.
