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

inputFiles_fileRequired

public void inputFiles_fileRequired(String[] fileRequiredin)

Parameters:

fileRequiredin - The fileRequired to set.

inputFiles_includeSubFolders

public String[] inputFiles_includeSubFolders()

inputFiles_includeSubFolders

public void inputFiles_includeSubFolders(String[] includeSubFoldersin)

getRequiredFilesCode

public static String getRequiredFilesCode(String tt)

getFileInputList

public FileInputList getFileInputList(VariableSpace space)

getResourceDependencies

public List<ResourceReference> getResourceDependencies(TransMeta transMeta,
                                                       StepMeta stepInfo)

Description copied from class: BaseStepMeta

Get a list of all the resource dependencies that the step is depending on.

Specified by:

getResourceDependencies in interface StepMetaInterface

Overrides:

getResourceDependencies in class BaseStepMeta

Returns:

a list of all the resource dependencies that the step is depending on

getEncoding

public abstract String getEncoding()

isAcceptingFilenames

getFilePaths

public String[] getFilePaths(boolean showSamples)

Specified by:

getFilePaths in class BaseFileMeta

Parameters:

showSamples - determines whether the paths being returned are dummy samples or the "template" representation. The samples woulc include things like sample step number, partition number etc ( filename_0_1.txt) , while the non-sample path would include a token ( filename_<step>_<partition>.<extension>)

Returns:

An array of file paths
