Method Detail

convertInsertionDtosToQueryResults

public static QueryResult[] convertInsertionDtosToQueryResults(List<InsertionDto> insertionDtos,
                                                               Map<SqlTableId,Set<SqlColumnId>> columns,
                                                               DbInfoDto schemaDto)

Parameters:

insertionDtos - specifies InsertionDto which indicates data we have been inserted into database or mocked

columns - specifies WHERE clause using a map from table name to involved column names

schemaDto - specifies info about schema that is used to parse printable value specified in InsertionDto to Object value

Returns:

extracted an array of QueryResult.

cartesianProduct

public static <T> List<List<T>> cartesianProduct(List<List<T>> values)

implement Cartesian Product e.g., (a,b) * (c,d) = (a,c), (a,d), (b,c), (b,d)

Type Parameters:

T - type of values

Parameters:

values - specified a list of sets for n-fold Cartesian Product

Returns:

results of Cartesian Product of the given sets

translateInsertionDtos

public static QueryResultSet translateInsertionDtos(List<InsertionDto> insertionDtos,
                                                    Map<SqlTableId,Set<SqlColumnId>> columns,
                                                    DbInfoDto schema)
