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]

Returns:
The appropriate StepDataInterface class.

exportResources

public String exportResources(VariableSpace space,
                              Map<String,ResourceDefinition> definitions,
                              ResourceNamingInterface resourceNamingInterface,
                              Repository repository)
                       throws KettleException
Since the exported transformation that runs this will reside in a ZIP file, we can't reference files relatively. So what this does is turn the name of files into absolute paths OR it simply includes the resource in the ZIP file. For now, we'll simply turn it into an absolute path and pray that the file is on a shared drive or something like that. TODO: create options to configure this behavior

Specified by:
exportResources in interface StepMetaInterface
Overrides:
exportResources in class BaseStepMeta
Parameters:
space - the variable space to use
repository - The repository to optionally load other resources from (to be converted to XML)
Returns:
the filename of the exported resource
Throws:
KettleException
