Xu Yang updated FLINK-13668: ---------------------------- Description: _FlatMapper transforms one Row type data into zero_, _one_, _or more Row type result data_, _and Mapper transforms one Row type data into one Row type result data. For most of practical_ *scenarios*, *the outputs are single column. Using these extend classes*, *we can be more focus on the algorithm development.* * *Add SISOFlatMapper for the Single Input column and Single Output column scenario.* * *Add SISOMapper for the Single Input column and Single Output column scenario.* * *Add MISOMapper for the Multi Input column and Single Output column scenario.* * *Add Param definition for SISOFlatMapper* * *Add Param definition for SISOMapper* * *Add Param definition for MISOMapper* was: _FlatMapper transforms one Row type data into zero_, _one_, _or more Row type result data_, _and Mapper transforms one Row type data into one Row type result data.
