Description copied from class: BaseStepMeta

The natural way of data flow in a transformation is source-to-target. However, this makes mapping to target tables difficult to do. To help out here, we supply information to the transformation meta-data model about which fields are required for a step. This allows us to automate certain tasks like the mapping to pre-defined tables. The Table Output step in this case will output the fields in the target table using this method. This default implementation returns an empty row meaning that no fields are required for this step to operate.

Specified by:

getRequiredFields in interface StepMetaInterface

Overrides:

getRequiredFields in class BaseStepMeta

Parameters:

space - the variable space to use to do variable substitution.

Returns:

the required fields for this steps meta data.
