getFields

public void getFields(RowMetaInterface row,
                      String name,
                      RowMetaInterface[] info,

row - The fields that are entering the step. These are changed to reflect the output metadata.

name - The name of the step to be used as origin

info - The input rows metadata that enters the step through the specified channels in the same order as in method getInfoSteps(). The step metadata can then choose what to do with it: ignore it or not. Interesting is also that in case of database lookups, the layout of the target database table is put in info[0]

nextStep - if this is a non-null value, it's the next step in the transformation. The one who's asking, the step where the data is targetted towards.
