public interface IDistribution

Interface for distribution of foreign key values when creating new rows of data.

The following constants will be discovered by reflection on class and used for presentation in the Anonymizer model:

• public static final String LABEL - label in the drop-down for Create task's Group and Parents when selecting Distribution type
• public static final String MAIN_LABEL - label for common parameter for the distribution
• public static final String PARENT_LABEL - label for individual parameter for each parent

Method Summary

Modifier and Type	Method and Description
static void	assignRow(CreateParent parent, List<String> columns, String[] row, int nParent)
static void	assignRowCol(CreateParent parent, List<String> columns, List<String[]> rows, int nrow, int nkey) Assigns values from the parent column to the foreign key column (nkey) in given row (nrow).
int	calculateNewRows(CreateParent[] parents, int numrows, List<String[]> existing) Returns the number of new rows necessary.
void	distribute(List<String> columns, CreateParent[] parents, List<String[]> rows) Assigns values to the foreign key columns in the new data rows.

Method Detail

calculateNewRows

int calculateNewRows(CreateParent[] parents,
                     int numrows,
                     List<String[]> existing)
              throws Exception

Returns the number of new rows necessary.
(This method should also do all preparation for later assignments).
by this time the CreateParent has had its occurrences counted.

Parameters:

parents - parents for foreign key assignments

numrows - number of existing data rows

existing - existing data rows

Returns:

number of new rows required

Throws:

Exception - of any type

distribute

void distribute(List<String> columns,
                CreateParent[] parents,
                List<String[]> rows)
         throws Exception

Assigns values to the foreign key columns in the new data rows.

Parameters:

columns - column names as used in the rows

parents - parent tables for foreign key assignements

rows - all rows including existing

Throws:

Exception - of any type

assignRowCol

static void assignRowCol(CreateParent parent,
                         List<String> columns,
                         List<String[]> rows,
                         int nrow,
                         int nkey)

Assigns values from the parent column to the foreign key column (nkey) in given row (nrow).

Parameters:

parent - Parent object

columns - List of column names corresponding to the rows

rows - List of data rows

nrow - which row

nkey - which parent row

assignRow

static void assignRow(CreateParent parent,
                      List<String> columns,
                      String[] row,
                      int nParent)

Parameters:

parent - Parent object
