Description

Seems jsefa 1.1.1 is on central, task is to:

• check license is still compatible with apache
• upgrade our version in our extension
• add header support for csv (and maybe more)

if it can help on the last point I used in a project:

public class JSefaWriterWithHead extends JSefaCsvWriter {
    @Inject
    @BatchProperty
    private String header;

    @Inject
    @BatchProperty
    private String headerLineBreak;

    @Override
    public void open(final Serializable checkpoint) throws Exception {
        super.open(checkpoint);
        if (isEmptyFile(checkpoint)) {
            transactionalWriter.write(header + ofNullable(headerLineBreak).orElse(System.getProperty("line.separator")));
        }
    }

    private boolean isEmptyFile(final Serializable checkpoint) {
        return checkpoint == null || Number.class.isInstance(checkpoint) && Number.class.cast(checkpoint).longValue() == 0;
    }
}
