Make an exact copy of this step, make sure to explicitly copy Collections etc.

Specified by:

clone in interface StepMetaInterface

Overrides:

clone in class BaseStepMeta

Returns:

an exact copy of this step

getXML

public String getXML()

Description copied from class: BaseStepMeta

Produces the XML string that describes this step's information.

Specified by:

getXML in interface StepMetaInterface

Overrides:

getXML in class BaseStepMeta

Returns:

String containing the XML describing this step.

setDefault

public void setDefault()

Description copied from interface: StepMetaInterface

Set default values

Specified by:

setDefault in interface StepMetaInterface

readRep

public void readRep(Repository rep,
                    ObjectId id_step,
                    List<DatabaseMeta> databases,
                    Map<String,Counter> counters)
             throws KettleException

Description copied from interface: StepMetaInterface

Read the steps information from a Kettle repository

Specified by:

readRep in interface StepMetaInterface

Parameters:

rep - The repository to read from

id_step - The step ID

databases - The databases to reference

counters - The counters to reference

Throws:

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

saveRep

public void saveRep(Repository rep,
                    ObjectId id_transformation,
                    ObjectId id_step)
             throws KettleException

Description copied from interface: StepMetaInterface

Save the steps data into a Kettle repository

Specified by:

saveRep in interface StepMetaInterface

Parameters:

rep - The Kettle repository to save to

id_transformation - The transformation ID

id_step - The step ID

Throws:

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

getFields

public void getFields(RowMetaInterface rowMeta,
                      String origin,
                      RowMetaInterface[] info,
                      StepMeta nextStep,
                      VariableSpace space)
               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.
