             throws KettleXMLException

Description copied from interface: StepMetaInterface

Load the values for this step from an XML Node

Specified by:

loadXML in interface StepMetaInterface

Parameters:

stepnode - the Node to get the info from

databases - The available list of databases to reference to

counters - Counters to reference.

Throws:

KettleXMLException - When an unexpected XML error occurred. (malformed etc.)

allocate

public void allocate(int nrfields)

clone

public Object clone()

Description copied from interface: StepMetaInterface

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

setDefault

public void setDefault()

Description copied from interface: StepMetaInterface

Set default values

Specified by:

setDefault in interface StepMetaInterface

getFields

public void getFields(RowMetaInterface r,
                      String name,
                      RowMetaInterface[] info,
                      StepMeta nextStep,
                      VariableSpace space)

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:

r - 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.

space - TODO
