Method Details

setUpOutputFile

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

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

Parameters:

file - file to be set up

restarted - true signals that we are restarting output file processing

append - true signals input file may already exist (but doesn't have to)

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

createNewFile

public static boolean createNewFile(File file)
                             throws IOException

Create a new file if it doesn't already exist.

Parameters:

file - the file to create on the filesystem

Returns:

true if file was created else false.

Throws:

IOException - is thrown if error occurs during creation and file does not exist.
