方法详细资料

generateProjection

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

generateNormalizedKeyComputer

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

Generate a NormalizedKeyComputer.

参数:

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

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

Generate a RecordComparator.

参数:

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.

generateRecordEqualiser

GeneratedClass<RecordEqualiser> generateRecordEqualiser(List<DataType> fieldTypes)

Generate a RecordEqualiser.

参数:

fieldTypes - Both the input row field types and the sort key field types. 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.
