Method Detail

setUpOutputFile

public static void setUpOutputFile(File file,
                                   boolean restarted,
                                   boolean overwriteOutputFile)

Set up output file for batch processing. This method implements common logic for handling output files when starting or restarting job/step. When starting output file processing, method creates/overwrites new file. When restarting output file processing, method checks whether file is writable.

Parameters:

file - file to be set up

restarted - TRUE signalizes that we are restarting output file processing

overwriteOutputFile - If set to TRUE, output file will be overwritten (this flag is ignored when processing is restart)

Throws:

IllegalArgumentException - when file is NULL

IllegalStateException - when staring output file processing, file exists and flag "shouldDeleteExisting" is set to FALSE

DataAccessResourceFailureException - when unable to create file or file is not writable
