Whether to push the output into the output of a servlet with the executeTrans Carte/DI-Server servlet

Constructor Details

BaseFileMeta

public BaseFileMeta()

Method Details

getFilePaths

public abstract String[] getFilePaths(boolean showSamples)

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

passDataToServletOutput

public boolean passDataToServletOutput()

True if the step passes it's result data straight to the servlet output. See exposing Kettle data over a web service http://wiki.pentaho.com/display/EAI/PDI+data+over+web+services

Specified by:

passDataToServletOutput in interface StepMetaInterface

Returns:

True if the step passes it's result data straight to the servlet output, false otherwise

writesToFile

public boolean writesToFile()

Returns true if the given step writes to a file, and false otherwise.

Returns:

true if the given step writes to a file, and false otherwise
