Method Detail

generateProjection

public GeneratedClass<Projection> generateProjection(RowType inputType,
                                                     int[] inputMapping)

Specified by:

generateProjection in interface CodeGenerator

generateNormalizedKeyComputer

public GeneratedClass<NormalizedKeyComputer> generateNormalizedKeyComputer(List<DataType> inputTypes,
                                                                           int[] sortFields)

Description copied from interface: CodeGenerator

Generate a NormalizedKeyComputer.

Specified by:

generateNormalizedKeyComputer in interface CodeGenerator

Parameters:

inputTypes - input types.

sortFields - the sort key fields. Records are compared by the first field, then the second field, then the third field and so on. All fields are compared in ascending order.

generateRecordComparator

public GeneratedClass<RecordComparator> generateRecordComparator(List<DataType> inputTypes,
                                                                 int[] sortFields,
                                                                 boolean isAscendingOrder)

Description copied from interface: CodeGenerator

Generate a RecordComparator.

Specified by:

generateRecordComparator in interface CodeGenerator

Parameters:

inputTypes - input types.

sortFields - the sort key fields. Records are compared by the first field, then the second field, then the third field and so on. All fields are compared in ascending order.

isAscendingOrder - decide the sort key fields order whether is ascending

generateRecordEqualiser

public GeneratedClass<RecordEqualiser> generateRecordEqualiser(List<DataType> fieldTypes,
                                                               int[] fields)
