counters - The counters to reference

Throws:

KettleException - When an unexpected error occurred (database, network, etc)

getFields

public void getFields(RowMetaInterface rowMeta,
                      String origin,
                      RowMetaInterface[] info,

               throws KettleStepException

Description copied from interface: StepMetaInterface

Get the fields that are emitted by this step

Specified by:

getFields in interface StepMetaInterface

Overrides:

getFields in class BaseStepMeta

Parameters:

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

origin - 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.

space - TODO

Throws:

KettleStepException - when an error occurred searching for the fields.
