                             Trans trans)

Description copied from interface: StepMetaInterface

Get the executing step, needed by Trans to launch a step.

Specified by:

getStep in interface StepMetaInterface

Parameters:

tr - The transformation info

trans - The launching transformation

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
