                          AIInOut output,
                          @Nonnull

                          List<String> inputVersions)

Decides whether the output file needs to be regenerated.

Parameters:

output - the output file

inputs - the input files . Caution: a file with name "-" is a placeholder for stdin - it is not a file.

writingStrategy - the writing strategy used to write the output file.

inputVersions - versions of all inputs

Returns:

true if the output file needs to be regenerated.
