Method Detail

doPostCleanupback to summary
public void doPostCleanup(BibEntry entry)

Overrides default org.jabref.logic.importer.ParserFetcher.doPostCleanup.

Doc from org.jabref.logic.importer.ParserFetcher.doPostCleanup.

Performs a cleanup of the fetched entry.

Only systematic errors of the fetcher should be corrected here (i.e. if information is consistently contained in the wrong field or the wrong format) but not cosmetic issues which may depend on the user's taste (for example, LateX code vs HTML in the abstract).

Try to reuse existing Formatter for the cleanup. For example, new FieldFormatterCleanup(StandardField.TITLE, new RemoveBracesFormatter()).cleanup(entry);

By default, no cleanup is done.

Parameters
entry:BibEntry

the entry to be cleaned-up
